Questions about comfort/convenience system W124
Hi all!
I've got a new-to-me 1992 300D that I'm trying to iron out the wrinkles in. I have a cluster of issues that I think are related, they include:
I don't care about the central locking system working, any "convenience" features, or any sunroof functionality. I just want the windows to operate with the switch, and to hopefully eliminate battery drains. The questions: -how is the convenience system controlled? Can I remove controlling elements like relay etc to disable the gremlins? Where the heck are these components located and what do they look like? Thanks ahead of time for the help folks! Brad |

Convenience relay is located under the rear bench seat on drivers side. Sounds like you could have a faulty window switch. Your model year does have the one touch auto down feature, but from your description, it is acting strange. If I remember correctly, you can’t just remove the module/relay from under the seat or you will lose power to the windows. I suggest pulling the module, inspect it for moisture, make sure it is getting a good connection, plug it back in and see what happens. If still not working, these modules are easy to find at most pull yards and were plentiful on fleabay and reasonably priced. I believe any convenience relay from a 1992-95 will work as well as 94-97 W202, but not positive. Actually, the cab module is different, but you won’t find one of those floating around, if you do people are asking crazy money for them.
