Heated seats dont work, fuses ok, switches light up, no heat

That is a common problem with that vehicle. It is likely that the seat heating elements are burned out. To find out if this is the case, you must unbolt the seat from the floor so you can tilt the seat back and gain access to the electrical connectos for the seat elements. If you have power and ground at the connector with the switch turned on, then the seat element is at fault.

Other than this, there are several other reasons why the seat heaters possibly will not work. In these cases, you will need a digital meter to test the voltage on the seat circuits as well as a wiring diagram to help you know where to perform the testing in order to locate the cause of the problem.

I would be happy to provide you with the wiring diagrams (and possibly, other instructional diagrams) if needed.
