E230 electrical problems
Hello everyone! I am new to this forum and looking forward to learn a lot. Im live in cali and just recently moved back to philippines. Anyways, my dad gave me his 1996 w210 e230 elegance. Its in good conditon interior/exterior. But, the following does not work: pwr windows, pwr locks, sunroof, side mirrors, pwr seats (but the passenger side works) rear headrest, horn. All the lights ext/int works btw. I took the car to a shop yesterday and the mechanic told me based on his diagnosis that i need to change the control modules. I believe its the k40 and k5 modules. The price is quite expensive for these modules. Any ideas what else could be the problem?? The fuses are all good. But the mechanic did not check the relays or voltage even.
Ive been gone for over 13 yrs and i do not know any good/reputable shops yet here. Thanks guys.

Hello plutoe. Thanks for the reply. I have not disconnected the battery yet. The switch to lock the locks does not work either. The key fob does not work as well. I will try to disconnect the battery today. Not sure if this would work, but my dad told me that the battery was dischared and the car sat in the garage for almost 2 months.

Don't spend any money on new parts until you isolate the bad ones. These systems are all connected via the CAN bus network, and a failure on one module can cause the others not to work. The central connector is under the door sill at the bottom of the a-pillar. You can disconnect one at a time, disconnect/reset the battery, and then drive around to see if the problem recurs. For me, the right rear window module was the gremlin, and I hear that's pretty common.
