I own a 2001 Mercedes-Benz C200K. The dome lights, the sunroof and automatic lights have stopped working. They will only work while the car is hot after leaving it in the sun at noon... Once the car cools down, the problem shows up again. I have checked all the fuse boxes and everything looks fine. All the other systems and controls are working fine. Any help would be really appreciated. Thanks.

SOURCE: fuel gauge stop working

Most likely your problem is the fuel sending unit in the fuel tank mounted with the fuel pump assy. The symptoms might let the gauge sit on or work intermittently then is goes to empty. DON'T let the dealer tell you its only replacable by changing the whole fuel assy.(400.00). This is not true. Look up your vehicle on the AC Delco web site at the top of the page click the link for part look up, it will ask you the year, style, eng size, etc. then you look at fuel , the part is actually called TBI Fuel Meter. If your truck is a 5.7 your part is #17113274 (around $100.00). This is a actual GM part number, some are the AC Delco part number that may have 2 letters and 4 digits, the dealer can cross reference it or order the AC Delco part. This kit comes with a new wiring harness, and instructions. Having said this the other symptom you may have is the gauge goes past full, this is because of a bad ground, most likely around fuel tank. I have replaced approx 6 of these sensors in GM vehicles( 2 of the same year and make as yours) in the last year, its cheap design lets it fail easily.

Battery base has a device that clamps the battery on a step/notch on the side. Use a ratchet with an extension to loosen. Once it is loose you can remove the battery.

Check the underside of your hood for a belt diagram. If it's not there, call your dealer with your VIN number to get the correct diagram.

This is the same location as your car
