mercedes 99 c280-all power windows and mirrors not working
Hey I was wondering if you ever found a solution to the problem..I am having the exact same problem on my car, none of the power windows mirrors or trunk release switch work,BUT when I disconnect the battery for 3 seconds they all work just fine for about 15 minutes...I checked the fuses in front in trunk and the relays out in the front they all are fine....
ANY suggestion would be appreciated..its driving me nuts!
For window problems on a mercedes c220-230-280-1994-2000 year.....p.s. mine was a 99 c280.
For all of you people having problems with windows...not working in the front or back..mirrors and airbag sign doesnt come on at the Window switch assembly by the gear knob...THEN you most like have the problem with the window switch assembly!!!!Before you buy a used one from ebay or local junk yard DO THIS:
around the gear shift there is a square plastic, take it out, take the whole window switch assembly OUT..it should all come out ...there is 2 plugs in the back of it...plug them off...
With the ignition on...put the plugs back on..and try the windows if they work..if they do it is the switch assembly faulty..just get another one
I would assume that you have checked the fuses under the hood...and in the trunk before..
Also another way is to take out the battery for a minute and plug it back on..i used to do that and switches would work fine for 20 minutes or so..than id have to take the battery out again or the plug on the switch assembly.
On the alldata...there was a note from mercedes that there is big problem with water entering through the back doors...so they advised sometimes to check the door modules..to make sure there isnt any corrosion ..and if there is signs of water in it sometimes just pluggin it off might let the other windows work ...
I hope this helps!!good luck!
