It sounds like you have one of two problems, first the switch could be bad causing the trouble or the motor has burned out for that function. The only way to be sure is to use a test light and test for power through the switch.

Here are some guides and diagrams (below) of the switch wiring.

Please let us know what you find. I'm interested to see what it is.

Cheers, Ken

This happens when the switch goes out here is how to replace it. I have also included the wiring diagrams so you can see how the system works.

I think yours falls into the one with a tsb onit. Your harness may be pinched under the seat causing this. Here is apic of where to look. This can cause other problems as well.

The seat controls for the drivers side seat no longer work, the heated seat controls on both drivers and passengers side to not work and the seat adjustment memory no longer works. It this a fuse issue or an electrical control issue?
