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

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?

Need to verify power and ground to the motors and/or switches.

These motors and switches are in the door? So door panel needs removing? Just asking before I chat with my mechanic
