if you find the main fuse box look down about 8 inches and you'll see a little black box take off the top and its the blue fuse

did you check fuse in relay?

The fuel pump relay is behind the battery. remove it and bridge pin #30 (should be under power) and #87 (that goes to the fuel pump). If the fuel pump kicks in you know the relay is bad

A. Check your transmission fluid. It's a hydraulic action. Low fluid will affect your transmission drastically. B. Your reverse clutches could be going out on an automatic transmission. C. Check your linkage, on a front wheel drive, it's usually attached towards the top of the transmission/ on a rear wheeldrive column shift, it can be attached on the side of the transmission. Play from a wornout bushing on that linkage can prevent the linkage from actually pushing the lever far enough to engage reverse. Hope this helps.

Sometimes, those motors for your wipers are a gear tooth. The inside of the actual housing for your wiper is the female side. After wear and tear/time, the teeth are worn down and A. the wiper will fail to turn completely or with any resistance slow down, or B. easily come off the motor. they are sometimes just pressed on. Check the teeth on the male gear to see if they're damaged or the inside of the wiper arm to see if they're damaged. If the teeth on the motor side are fine, you can get away with just buying a new wiper arm versus buying a new motor. Hope this helped.

OVP will not cause it to stall once engine is running. Check the distributor cap and rotor as they often burn out. Coil can fail too.

could be worn clutch bad slave cylinder or cable

can not start good

Relay should be behind fuses under a screwed down cover. My question to you is why would you think the relay is bad? Check voltage at the pump as someone turns the car to on. At this age it's most likely a dead or dying pump. Other things to consider are OVP relay (behind the battery) , coil dead, general tune up ie plugs, wires, cap and rotor.

there are 2 fuel pump relays on the mercedes so it is unlikly that they have both gone on it....check your over voltage relaytell me what happens

its probable the viscos fan not working properly does it over heat only when its standing still but is ok when its moving if this is the case its the rad cooling fan

It was OK. before? Maybe there is a delay switch

Have you tried to clean and replace the ground wire/cable? That will usually solve the problem. If that doesn't work look at the pigtail where the bulb is plugged into. Hope it helps.

It works together with throttle position sensor .
