hey guys i cant control the heat, A/C or anything. i can only control when to turn it on and where to blow the air out, and the temp, it gets really cold and really hot and everyting in between. just cant control the speed of the air, and i cant turn the fan off unless i turn the car off and sometimes it still comes back on automatically after i start it again. i press the off button and it just goes low but doesnt turn off? anyone know why. is it all messed up? can i fix it or should i just leave it? thanks

Jon

Blower Control Module

more than likely it is your blower control module (BCM). Moisture gets into it and corrodes the traces making your a/c and temp control go completely haywire. You can usually pick one up on ebay for around 30-40 bux in fairly good condition.
