1990 Mercedes-Benz 560SEC Q&A

1990 Mercedes-Benz 560SEC Question: 1987 560 SEC, unable to adjust both front seats via switches on the door fuse ok

I checked fuses they are not blown, what should I look for next? Any suggestions? Since both front seats can not be adjusted I am wondering if a wiring issue or module may be out. Where can I go in the car to check? -
Answer 1
Need to verify power and ground to the motors and/or switches. -
Comment 1
These motors and switches are in the door? So door panel needs removing? Just asking before I chat with my mechanic -
Comment 2
Yes, You need access to them. -
