My AC & rear defrost will not work. The climate control lights does not come on at all when I press the buttons. My ac is charged the blower comes on but its nlowing out any cold air at all. Could it be because the climate module is not recognizing when I press the Ac button & no light come on. I was to that it may be an electrical problem or either the climate control module needs replacing Help? Any ideas

Try pulling your hvac fuse for 60 seconds with key on then reinstall sometimes it resets everything otherwise have it scanned.

Thanks for the quick responce. I removed the hvac. Now while the key is on it blows some cool air but doesnt get as cold as it should & when I start the car it continues to blow hot air. Yet the climate control lights still does not come on. Its been scanned before I posted this question & I was told there are no blown fuses.

See if the item in pic it's on thepaassenger side is getting power that opens doors to change temp it may not be. Make sure your a/c line going into pass compt is getting cold as well as it could still be aprobem there. The actuator will be tough to see to fix it you need to remove the dash it's above the blower and you might get to it through glove box but probably not.
