gbhrps Posted January 14, 2014 Share Posted January 14, 2014 djmark7, Under the seats are the wiring connectors for the seat heater of each seat. If you pull the connectors apart and turn on the switch, a test light placed on the two contacts for the wiring harness side (not the connector that goes up into the seat itself, but the one from under the carpet) should light up. If it does, your problem is in the heating grid and wiring under the seat covering (leather or cloth). If the test light doesn't come on, your problem may be a relay for the seat heaters, a fuse, or the switch itself. If we knew the year and model of your car, someone might even be able to post the FSM diagnosis chart for you. Link to comment Share on other sites More sharing options...

johnceggleston Posted January 14, 2014 Share Posted January 14, 2014 the wires / heating elements in the seats will can break with age. this will cause a no heat situation. is it both seats or just the driver side? Link to comment Share on other sites More sharing options...
