The driver's seat in my 1989 Mercedes 300 SE is changing positions on its' own. What can I do to stop it?

The best source would be www.beckerusa.com

Go onto scribd.com and register (for free) and type in mercedes 300 e and look at the 2nd one in line. Yours is a 124 body and the owner's manual is labeled 200, 230, 260, 300. On page 86 it has a list of fuses and their location. I hope this helps. I've worked on Mercedes for years and I know how hard it can be to retrieve info on these cars. Let me know if you need anything else.

If the buttons stick yes. Call a junkyard and get a replacement.

It is over by the battery, go to benzworld.org or peachparts.com on how to make a code reader and how to read the codes you find.

Sorry for the long delay. Due to the bad economy, Questions have risen 50% in the last 4-months.

maybe the coils or sparks need to be changed

happened to me the same thing taday on a 1988 190E, just noticed that brake lamps and reverse lamps didn´t work either, fuse was OK but I replaced it anyway and now everything is working fine

Motor on the seat may have gone out, contacts in switch got dirty or worn, or assembly reached limit and stuck. Try sitting in it pushing back hard and adjust. If not youll need to replace switch,b take seat apart to fix or replace.

Ok that changes thing, is the low pressure line from the compressor getting frosty cold?

fuse in relay behind battery may be the porblem
