The drivers side seat worked perfectly a few weeks ago, and suddenly went dead. I can't adjust the seat at all anymore, nor does the seat heater work now either. The passanger seat still works perfectly though. I checked as best as I could underneath the seat with a flashlight, jingled all the wires I could and saw nothing wrong. Then I checked the manual for possible fuses, but no fuses corispond to both heat and motors on only one seat. I still gave a visual inspection of the only possible fuses (not checking resistance) and they both appeared fine to me. Any ideas, or is an auto shop my best option?
