Like he said...
Had the same problem a while back. Simple DIY.

Basically take a few things out of the way, unplug old and plug in the new.

Google it.

thx for the feedback but now a new issue. as my Climate control was on and off a little bit on its own, i proceeded to do a maintenance change of the thermostat and water pump. after everything was put back together, the CLIMATE CONTROL WONT TURN ON AT ALL.

the system throws out a code 74 (ac compressor control). the FSR was replaced on the car at 50 and i was told the FSR has nothing to do with the actual climate control turning on (just the fans).

PLEASE HELP
