My 1999 CLK430 drivers side seat switches either don't work at all, or work in the opposite direction than they should. Some work some don't. The one that bothers me the most is the seat tilt not working. I want the front to tilt down but it won't. Feels like I'm sitting in a bucket. I've tried doing the headrest synchro procedure in the operating manual but it does not fix the problem. Ideas? I've searched for this issue on the forum with no luck.

Thanks in advance.
