Need a new driver’s side headlight.

ANSWER : Hello. Ironically, I happen to have a 2000 CLK 430 as well and I experienced an almost identical scenario as you did. I had a fog light out on my vehicle, thinking it was a bulb I went ahead and replaced the light bulb but once I replaced it it still did not fix the issue. Upon further inspection of my vehicle I found that the some of the insulation around the wiring leading to the fog light was brittle and causing wires to be exposed. I taped the wires with some electrical tape because Mercedes-Benz has a very sensitive electrical system and if a wire is exposed it will cause resistance. If the electrical system senses too much resistance it will cut power off to that component to help protect other electrical parts. I suggest to have a technician such as one from YourMechanic inspect the wiring of your fog light that is out, check the fog light fuse in the side fuse compartment, and also check the clearance light bulb. The clearance light bulb is a small bulb located under the fog light and is integrated into the fog light circuit. If the clearance light is out it will interrupt the fog lights power. On my vehicle it was a clearance light being out and the damaged wiring to the fog light causing my fog light to be inoperative.

ANSWER : Hello, and thank you for writing in. There are several reasons why your vehicle may pull to one side or the other while braking. The first thing to consider is a warped rotor or faulty brake pads. When you replace the pads and rotors on the vehicle you need to replace two or four of them at a time. Replacing just the one on passenger side will not be adequate. With that being said, you are more concerned about the rotors then you are the calibers. The calibers hold the brake pads to the rotors when needed. It is a warped rotor or a bad brake pad that will cause the vehicle to pull. You should start with the full service brake job including machining the rotors to flatten them out if needed, and all new brake pads. If the problem continues after that, get an alignment done on the vehicle. For more help contact our service department to schedule an appointment.

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.

ANSWER : Your vehicle has a recall on the headlight wiring connectors and bulbs. If the connectors do not have a made in Mexico tag on them, then they will need to be replaced with new bulbs and connectors as per recall E04 dated March 2005. The recall has to be performed by a qualified dealer and should be free of charge. However, if this doesn’t solve your problem, have a certified technician check your headlight’s out. They will be able to diagnose the issue and make any necessary fixes.

ANSWER : Request that a professional alignment shop use a tram to carefully and completely measure the unibody and compare all such measurements against the data set out in detail in your vehicle’s Factory Service Manual. Using that strategy it will be easy to conclusively and authoritatively determine if the unibody is damaged. If the unibody was damaged in the collision it will have to be repaired, if cost effective, or obviously the insurance company will have to make you whole on your claim for damage. If you have any further concerns, do not hesitate to contact YourMechanic as we are always here to help you.

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.

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.

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.
