Have an electrical issue under driver side 2000 Jeep Cherokee Laredo

There is a hole in my fender on driver side and it is spraying water and salt on two wire connectors. They are white blocks with bunch of wires going through them with a bolt in the middle. They are next to fuse box. All I need is the name of the part and if possible how to replace. Thanks.

My car has 200000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello – the block connectors you describe are no doubt part of the vehicle wiring harness, and are likely not available as separate components. In addition to repairing the fender (or fender liner) hole you mention that is causing water and salt exposure, I would at least unbolt the 2 connector halves at this point to inspect the connections to determine if they can be repaired. Clean all the connections first with electrical contact cleaner, coat with dielectric paste, and re-assemble the connectors. Wrap with duct tape and shield with plastic or whatever else is most appropriate. If the connectors are not salvageable, check with Jeep or wiring aftermarket suppliers for possible wiring harness repair products.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

Electrical system, engine, and powertrain issues are among the top complaints received by the NHTSA from vehicle owners. The 2020 Jeep Cherokee continues to push for excitement with enthusiasts.
The throttle position sensor(TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.
With an average of 200,000 miles, you can expect the Grand Cherokee to last you around 20 plus years which is more than enough time if you`re looking to get the most on your investment.
Cherokees from 2014 and 2015 are the vehicle`s worst years. These have many recalls and complaints, most regarding critical powertrain components. The best years for the Jeep Cherokee include those from 2018 and 2020. These have fewer problems and have the highest owner ratings.
* 258ci cranks from the 1972 to 1980 model years are often considered the best to use in 4.0L stroker motors because they are stronger and smoother.
When looking at the worst-performing models of the Jeep Wrangler, 2012 took the win. Among the issues it had, there have been 9 recalls, making it the worst for Jeep. The 2007 and 2008 Jeep Wranglers are not too far from that, as they have 10 and 9 recalls, respectively.
In particular, 2021 Model Jeep Wrangler have been the subject of numerous complaints about electrical problems. These issues range from simple annoyances, such as faulty interior lighting, to more serious problems like complete loss of power while driving.
Regardless of model, it`s a good general rule to avoid model years with many customer complaints, mechanical difficulties, and expensive upkeep, just like any other product you buy. Grand Cherokee model years 2011, 2014, and 2015 are the most likely to have mechanical flaws and, therefore, some of the worst to buy.
A malfunctioning TPS will cause your engine to run poorly. Generally the engine will idle fine but will have difficulty accelerating. This is because the computer isn`t telling the engine to inject as much fuel as is required, while at the same time airflow is increasing.
Compared to other used SUVs near you, the average lifespan of a Jeep is much higher. If well-maintained, most Jeeps can exceed 200,000 miles, and some people have even been able to maintain their Jeeps for up to 20 years.
They explain that the longevity of your Jeep depends on proper care and maintenance, as well as the model year. Some earlier Grand Cherokee models last beyond 200,000 miles, while others meet their makers around 150,000 miles.
Transmission Problems

Another potentially expensive repair are the 8-speed transmissions found in 2014-2017 Grand Cherokees with the 3.6L V6. Owners report the transmission shuddering and “bumping” when coming to a stop and general hard shifting.

The Laredo X has power four-way lumbar support and a power eight-way driver`s seat that the Limited offers and adds memory settings to. Only the Limited has available ventilated front seats and heated second row seats. A power sunroof is available with the Laredo X and standard on the Limited.
All things considered, a conservative estimate for the maximum lifespan of a typical fifth-generation Jeep Cherokee falls somewhere in the 175,000 to 200,000-mile range, though outliers, as with any car, exist for the Cherokee as well.

Driver side door lock button not working, and passenger side sliding door makes a buzzing noise
ANSWER : Hi there. These door issues are common on this vehicle. Most of the time the main issue is the master door lock switch on the driver door. It sounds like you already replaced that. As for the sliding door problem, most of the time, this is a failure within the door module or it can be a connection issue.

I typically take the door apart and check the connections on the module and inside of the door just to make sure that there is nothing apparent in there. If the connections and the wiring are fine, then I use a scan tool to check the module to see what the inputs and outputs are doing. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your door problem and recommend a repair.

Driver Side Inner & Outer Tie Rods and driver side strut being bent.
ANSWER : From what you’ve described, the damage was most likely caused from hitting a pot hole. If the damage was from a pot hole on the right side, in some cases it’s possible for the force to transfer over and damage the left side as well. If you’d like a second opinion on this, consider YourMechanic, as a certified technician can come to your home to diagnose your car’s suspension system and confirm these suspicions.

Lowbeams on drivers side will not shut off
ANSWER : Hey there. To be completely honest my friend, you might need to go back to the basics and purchase a detailed wiring schematic for this vehicle to determine where the electrical fault exists. Quite often when an electrical fault like this exists, the best solution is to trace every connection to see where the fault is triggered. Most of the time, it’s an exposed wire or ground issue that causes the circuit from the switch to the lights to fail. If you need help here, one of our professional mechanics can come to your location and complete an electrical problems inspection.

Power mirror on passenger side will not retain it’s setting driver side works perfect.
ANSWER : A technician with an advanced scan tool can verify the issue. The mirror system is complex and involves many modules. The Body Control Module is a possible cause, but it’s doubtful; replacement requires reprogramming, which requires special equipment. I would check the driver’s and passenger’s door modules; toggle or move the switch on the driver’s side to see if it causes the problem, and ensure that the mirror glass itself is not loose on the passenger’s side mirror assembly.

Without diagnosing the problem with advanced equipment, the issue is hard to diagnose. A qualified YourMechanic technician can show up to the location of your vehicle with a scan tool to inspect and diagnose your power mirror issue.

Have a 2000 Jeep grand Cherokee Laredo 4.0. The voltage gauge is not working and it spits and sputters while alternator is hooked up.
ANSWER : Hi there. If the alternator is causing the volt gauge on the dash to stop working, then the polarity on the wires is backwards. Check the power wire to the alternator and make sure that its hooking up to the positive side of the battery. If its hooked up properly, check the voltage coming out of the alternator and make sure that its a positive charge. If the charge is normal, then check for AC charge on the alternator. The alternator should have no more than 35 AC voltage. If the alternator has more than 35 AC voltage, then the alternator needs replaced. The voltage regulator in the alternator is not working. If you need further assistance with the volt gauge not working with the alternator hooked up, then seek out a professional, such as one from Your Mechanic, to help you.

Front driver side tire moves side to side when jacked up
ANSWER : If you can move the tire in and out when on a jack then you may have a few different possible problems. The inner or outer tie rod ends may be worn. Your steering gear may also have worn bushings. I would recommend moving tire back and forth while holding onto the tie rod ends to see if looseness is felt and replace any loose components. An alignment will need to be done after repairs.

I am having issues with the defroster blowing cold air on the driver side
ANSWER : Hi there. There is a blend door issue on your ducting to your heating and air conditioning system. Check all of the blend doors and make sure that they are working. The blend door that is not working properly can have a bad motor or a vacuum line leak. Look for any vacuum lines that may be disconnected and also any blend door motor wires that may be exposed causing a short. If you need further assistance with your driver side having reverse effects of blowing air over the rest of the vehicle, then seek out a professional, such as one from Your Mechanic, to help you.
