heater switch

Post by prchrman » Sun Nov 15, 2015 6:55 pm

runs the fan on high est setting only (assume same for air but have not tried yet and cant remember last time I had air on )
anyway, there is a module behind the switch 1st likely cause? second would be the relay/module under the glove compartment?

Probably the resistor pack under the glove box, but I've also heard of the fan switches getting hot and melting. I'd take the switch out. If it looks ok I'd replace the resistor pack.

You can buy the switch at Advance, I've replaced it twice. Or it could be the resistor

It's usually the resistor when only high works.

Building a capable off road Jeep is easy...building a street legal one that you can drive two hours away to wheel and then drive to work the following morning is the challenge.

Agree. Had to replace mine once. IIRC, it's behind the glove box. Unhook the wiring harness, remove two bolts, slide it out and slide the new one in. Ten minute swap.
