Hey guys. My climate control unit used to work fine. Push a button, it worked. Nowadays nothing happens until it seems to warm up. I already replaced fuses and I don't believe it's the blower motor (replaced last year). The recirculator button's light doesn't light when any of the control unit's buttons are engaged. Once the unit warms up and the blower kicks on does the recirculator light come on. Hence I believe it's the control unit itself that's faulty. The defrost button doesn't even do anything. I've already taken the unit out and resoldered the connections on the main board but that didn't change things. No visible burnt marks anywhere on the main circuit board. BTW, when it does finally kick on if I have hit any buttons before it kicked on the ccu appears to remember what buttons I hit and goes thru them all before stopping at the last button press. (if that doesn't confuse you ) Any help would be really appreciated.
