Possible wiring issue
The driver's side headlight is out and has been replaced twice in the last year. I think there is a bigger cause after reading similar stories online. Could it be the wiring or something else causing the bulbs to burn out?
Experienced mechanics share their insights in answering this question :
The bulb wiring would need to be checked for any overheating problems. The bulbs should not be touched with fingers when installing them or premature failure will result. The light housing needs to be checked for excessive water in the housing that can get on the bulb and crack them when they are hot. It’s important to replace the bulbs only with other approved bulbs. If you need help with this, a certified mechanic, such as one from YourMechanic, can come to your home or office to properly inspect your headlights and replace the bulbs if necessary.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Push the point of the tester through the wire insulation behind the socket to make contact with the wire. The tester should light for two of the three wires (the ground wire won`t light). If it lights for two wires, the wiring is good. Simply replace the socket.
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner`s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
What Common Problems Does the 2009 Chevrolet Malibu Have? Common issues with the 2009 Malibu include power door lock failures, damaged headlight wiring, and clunking noises while turning. Power door lock failures are the most widespread problem, happening at around 60,000 miles.
There is a good chance that your ballast is the cause of your lighting problems if your headlights are dim, changing colors, buzzing, or flicker. When inspecting it for potential issues, any burn marks, leaking oils, or swollen casing are indicators of failure.
Used in “flip-up” lights, which fold out of the body of the vehicle, headlight closure relays are essential for headlight operation. This relay is located in your main fuse box or panel.
All the electrical systems in your car, including the headlights, are protected with fuses. These are designed to `blow` and break the circuit if too much power comes through them. This protects all the components on the circuit. If a headlight fuse blows, it could cause the headlights to stop working.
However, one of the most reported 2018 Chevy Malibu problems is its electrical system. The National Highway Traffic Safety Administration (NHTSA) lists numerous customer complaints about the 2018 Chevy Malibu`s failure to recognize when the vehicle is in “Park,” which means that they cannot turn the car off.
We recommend staying away from the 1999, 2000, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2013, and 2016 models. Engine problems are the most common issues that appear when there`s something wrong with the Chevy Malibu. This trouble can cause expensive repairs most drivers can`t afford regularly.
Error code P0700 signifies that a malfunction has been detected in your vehicle`s transmission controls. Most modern automobiles feature a specific control module as it relates to the vehicle`s automatic transmission. This module is known as the Transmission Control Module (TCM).
In most vehicles, there is typically a single fuse for both headlights rather than a separate fuse for each headlight. The headlight fuse is usually located in the fuse box, which is typically located in the engine compartment or under the dashboard on the driver`s side of the vehicle.
Among obvious signs that your headlamps aren`t properly aimed are oncoming drivers flashing their lights at you because your lights are blinding them even without your high beams turned on, or the road ahead is brightly illuminated for only 20 feet or so, meaning the headlights are aimed too low.
No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or “plug-and-play” LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs. Incandescent and halogen lamps do not require a ballast.
A HID Ballast is a device required by a xenon headlight (also for fluorescent lamps) to regulate voltage and current supplied to the lamp during the start. It also provides enough voltage and current throughout the drive.
The Light Control Module (LCM) is an important component of a vehicle because it controls all of the car`s lights, as well as the horn function.
The purpose of a relay, whether a headlight relay or any other type, is to allow a small current to control a larger current. Headlights require a much larger current than the switch on your dashboard (or steering wheel stalk) can handle.
Overloaded Circuit
The most common cause of a blown fuse we see as experienced Electricians in Sheffield is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once.
Connect the black (negative lead) of the multimeter to a good ground on the frame or to the negative battery terminal. Set the multimeter on the voltage scale for 20 volts. Turn on the headlights and select low beam with the dimmer switch. The reading should be around 12.4 volts or so.
Under certain conditions, an error in the vehicles` engine control module (ECM) software. can cause data used by the ECM to become corrupted. When this occurs, the ECM may. send a signal disabling the engine`s fuel injectors.
The most common car electrical system problems are problems with your car battery, an alternator that isn`t working properly, loose or failed spark plugs, a fatigued solenoid or starter, bad battery cables, electrical fuses that are blown, loose wires, or problems with your ignition switch.
The 2023 Chevrolet Malibu has a predicted reliability score of 85 out of 100. A J.D. Power predicted reliability score of 91-100 is considered the Best, 81-90 is Great, 70-80 is Average, and 0-69 is Fair and considered below average.
The most common complaints about the 2010 Chevrolet Malibu are about the steering, electrical system, electronic stability control, and exterior lighting. Of these, issues with the electric steering have been the biggest concern for drivers.
What the P0107 code means. P0107 is the general code for a problem with the MAP circuit sensor having too low voltage input to the Engine Control Unit (ECU). This means the voltage input to the ECU is . 5 volt or less which means that it is not in the correct lower range for proper engine operation.
The colors of the wires are red, black, and white. Red becomes the first positive with black the second positive. The white light becomes ground. The 3 wire light can best be installed as a blinker and brake.
This circuit uses four relays, and the left and right headlamps (both the low-beam and high-beam bulbs) are individually fused. In the event of an overcurrent situation on either headlamp, both the high-beam and low-beam bulbs will go out if the fuse blows, but the other headlamp will not be affected.

Possible electrical issue
ANSWER : Hello. Most of the time this is not a harness problem. It is typically caused by an issue with the combination switch. This switch typically shorts internally and causes this. I have also had fuse box issues that have caused this but that is not as likely. The only way to know for sure would to test the circuit with a voltage meter to see where the voltage is lost, which is typically at the switch. If you need help with fixing this taillight issue, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose why the lights are not working.

Will disconnected wires from the o2 sensor cause the car to die it was a blue wire and a black wire
ANSWER : There is not a blue wire going to the O2 sensor but a blue wire going to the camshaft sensor. Any bare wire that goes to the computer may cause the computer to get shorted and stall the engine. I would have the wires repaired along with the exhaust falling off and then check all the fuses to see if some of the fuses were shorted from the bare wires. Once all fuses are replaced that were bad then see if it will start. Have a mechanic diagnose the problem for you if you need help.

I have a 2016 kia forte. A rodent ruined my wiring harnesses causing safety and operational issues. Kia says the harnesses have to
ANSWER : Hi there. The automotive manufacturer is 100% correct in their estimation about splicing a wiring harness. Today’s vehicles are 100% controlled and monitored by electrical and computer operated systems. These systems require a clear and unaltered wiring system that sends electrical signals from sensors and components to the ECU and back. Splicing or altering the wiring in any way is very unsafe and can disable several safety systems including air bags, anti-lock brakes and other systems.

Car will crank but no start… Fuel pump not coming on. New pump, relay, etc. Will start when hot wire runs from pump wires to bat
ANSWER : There are a couple of approaches to take here – either start from the battery and work "towards" the fuel pump, fuse box, ignition switch, fuel pump relay, and wiring connections in between. Or, as you have done, start at the pump with 12v, and move backwards towards the battery. This will require a GM service manual, or wiring diagram at least, with connection locations as well.
I would recommend having a certified technician from YourMechanic diagnose this starting issue, get an accurate assessment of damage and cost estimate for repairs. YourMechanic.com can dispatch a mobile, professional mechanic to your location for this repair.

Blinking Check Engine Light, issues with rpm, possible spark plug issue?
ANSWER : Hey there. The gas smell you experience is most likely due to the unburned fuel due to the engine misfiring. Since you smell unburned fuel, the cause is most likely spark-related. If any spark plug is not firing correctly, the spark plugs themselves can be at fault or they can be the effect.
If an ignition coil is not firing the spark plug, then the bad coil is the cause and the misfiring plug is the effect. Also, the ignition coil may not be firing properly due to the coil itself being shorted or possible receiving a poor signal from the engine control unit.
You should have a certified technician look into the Check Engine Light as soon as possible. Continued driving with the light flashing can cause internal engine damage if not corrected.

I need to know which body wiring harness goes to my truck- VIN lookup
ANSWER : My best recommendation would be to contact your local dealership. If you give them your year, make, model, vin, and a description of the wiring harness that you need, they should be able to give you some information in regards to the part number. Unfortunately, the dealership is about the only possible chance of tracking down this harness other than getting one from a junk yard.

Good evening , I want to see if it’s possible to swap the engine to a small block Chevrolet. What are the main issues?
ANSWER : Hi there. You can swap the engine in your vehicle, but you will need to swap the electrical system for the engine to run properly. If you plan on using a newer model with the computer system for OBD2, then the computer and all of the electronics including the fuel system needs to be swapped over. The exhaust system will need to be swapped over as well. Plus, either you can get an adapter plate and a spacer for the clutch and adapt the Toyota transmission to the Chevrolet engine, or you will have to install the engine with a GM transmission. If you need to change the transmission, you will need to modify the driveshaft to fit the transmission, have the right length to the differential, and fit the differential. You also will need to modify the engine mounts to fit the engine and transmission. If you need further assistance with your engine swap, then seek out a professional, such as one from Your Mechanic, to help you.

How can I find the correct chassis wiring harness for my truck?
ANSWER : The harnesses are referred to in GM parts catalogs as "body wiring" and "rear lamp wiring". However, the correct wiring harness for your vehicle can only be found via a VIN number search in the catalog. It can’t be searched simply by "model" due to the large number of vehicle variants, for example RPO codes. There is no way to look up a harness part number without your VIN number so please send it. Unfortunately, many of the wiring harnesses, including many within the two "categories" you are inquiring about are discontinued by GM. Inasmuch as some are available it is still worth looking up and confirming whether you can get it or not, but you may be in a situation where you have to fabricate your own replacement harness which is not a big deal particularly if you have the old one available to use as a template. The biggest issue are the cable terminations but many of those may be standard and thus pigtails will be available. You could actually make a better (higher quality) harness than that originally used on the vehicle. Please let us know how we can assist you further.
