I have heated seats in my 04 ST the driver side heated seat don't work but the passenger side does.Is there an easy fix to this or do I have to take it in.Any help would be Awesome thanks.
Does the LED on the switch come on when you press the button? If not, it's probably the switch. I'm experiencing the same problem right now, and I think it's the switch.
Had a similiar problem with mine, but the switch did light up. Somehow, I lost the ground to the heating element. I was able to pull the seat and cut the ground wire coming from the element near were it plugs in under the seat and re-ground it. Works again! Check to see if you have a ground to the element if your switch lights.
