Gauges and Radio flicker when driving

Really strange things are happening while driving my car. All the sudden the warning lights start flickering and I hear a clicking noise, then the power steering temporarily stalls.
Experienced mechanics share their insights in answering this question :
This could be caused by a faulty power steering cooling fan. The Mini’s have an electrically controlled fan that will de-activate power assist if the fluid temperature exceeds a programmed standard to prevent damage to the power steering system. These fans are problematic and may need to be replaced if the fan activation signals check out fine. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will have the tools and training to diagnose the power steering system and correct any issues once the problem(s) has been isolated.

Gauges flickering and the car won`t start usually indicates a power problem. Usually, a battery problem comes with clicking sounds. To determine the source, call a mobile mechanic and ask for help conducting a battery inspection.
When Your Dashboard Lights Flicker and Your Car Won`t Start. If the car won`t start at all and the dashboard lights are flickering, it`s likely that the battery does not have enough charge to crank over the vehicle. In this scenario, you`ll likely need to replace the failed battery.
Most likely, flickering dash lights are due to problems with the alternator. In addition to recharging the battery, the alternator is in control of running the electrical components in your vehicle. If the alternator is failing, it may not be able to steadily supply enough current to all the components.
Tighten the bulb to ensure it`s securely in the fixture. If it`s a lamp that`s flickering, check the plug to ensure it`s secure in the outlet. If you have a dimmer switch on the light, the cause of the flickering may be that you don`t have a dimmable bulb in the fixture.
2. Failing Alternator. When the alternator starts to give out, your car`s electrical output is affected. This could result in flickering, dimming, or inoperative headlights, as the headlights depend on power from the vehicle`s battery.
Bad bulbs or fuses

If the car battery isn`t the reason for your flickering car lights, it may be a bad light bulb or a bad fuse. Bulbs are an easy and quick fix and present an opportunity to upgrade to new energy-efficient LED bulbs.

Flicker – terminology

In electrical engineering, flicker is defined as short-term voltage fluctuations in the power supply system. This can cause lamps to flicker, as the brightness is proportional to the applied voltage. Other technical devices are also sensitive to voltage fluctuations.

The majority of electronics and appliances in the U.S. can`t handle voltage above 169. But when a power surge occurs, it causes a flow of electricity that spikes above 169 volts, resulting in an arc of electrical current. This arc generates heat that is damaging to electronic components and circuit boards.
While you are driving, if you notice the needle on the speedometer jumps erratically from one number to another, the speedometer cable is most likely damaged or the sensors on the driveshaft are not accurately sending the signal through the cable.
If bulbs are flickering when the light string is moved, this is likely caused by damage to the wiring and the light string will need to be replaced.

the most relevant questions and answers related to your specific issue

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

Brake sensor is to sensitive causing brakes to flicker while driving. 2005 Mercury Montego
ANSWER : Hi there – your brake light switch needs a minor adjustment. It is adjusted too "tight" or close to the brake pedal lever, or possibly has failed. Adjusting/replacing it will eliminate this flickering problem. I recommend a brake light isn’t working inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

my temperature gauge rises slowly when its in drive and idle. once i start driving, it quickly drops. what could be the issue?
ANSWER : Hi there. From the description you have provided, this could be an inoperative radiator cooling fan issue. Turning on the a/c, this should turn the radiator cooling fan(s) on, which would help identify whether the cooling fan(s) are capable of turning on. If, the fan(s) turn on, then it could be a faulty coolant temperature fan switch. If, the radiator cooling fan(s) don’t come on with the a/c on, it could be, a blown radiator cooling fan fuse. It could be, a faulty radiator cooling fan relay. It could be, a faulty radiator cooling fan motor. I recommend having your vehicle’s temperature gauge be diagnosed and repaired by a certified technician, such as one from YourMechanic.

While driving my drive decided not engage when I had to stop
ANSWER : Hello. The traction light is like a check engine light for your steering and suspension system. A technician could use a scan tool to pull any error codes to help pinpoint which component is faulty. I believe the problem your vehicle is having is a faulty shift solenoid. The transmission control module sends a signal to the shift solenoid for the shift solenoid to control the transmission shifting. By you paddle shifting you are basically bypassing the shift solenoid because you are controlling the transmission shifting yourself. If the shift solenoid fails completely you will not even be able to use the paddle shift function. It will be best to have your vehicle inspected by technician as soon as possible.

Gas gauge isn’t working. Sometimes the speedometer and the temperature gauge doesn’t work. Limited lights around gauges and radio.
ANSWER : Hi there. The dashboard lights are burned out in the dash and the dimmer switch could be worn causing the lights to be weak. The gauges that seldom fail to work is most likely a loose wire in the dash panel. The fuel gauge that is not going to E when shutting off the car has a damaged rheostat within the sending unit. The sending unit is in the fuel tank attached to the fuel pump. If you need further assistance with your gauges not working, then seek out a professional, such as one from Your Mechanic, to help you.

Car radio will not pick up radio stations.
ANSWER : There are multiple issues that could cause a radio to not pick up an AM / FM signal. In most cases it’s due to faulty wiring, a loose ground wire or the wiring running to and from the antenna. However, it’s also possible that an internal component inside the radio such as an electrical relay has been damaged. It might be best to purchase a new tuner; as diagnosing and fixing this issue would most likely be more expensive than the cost of buying and installing a new one.

Temperature gauge does not work – 1998 Mercury Grand Marquis
ANSWER : You will need to test the computer to scan for data of the temperature sensor to see if the computer is reading the correct temperature as tested externally on the coolant sensor. If the sensor is not accurate then replace the sender. If the sender is accurate then you will need to have the temperature gauge replaced.

Shifting issues from drive to reverse and back to drive
ANSWER : Mercedes has a dealer service order (#Order No: S-B-27.19/118A
) that addresses diagnosis, and possible dealer repair of the transmission for your model. Check with your dealer to confirm coverage of this.
