Before you guys go off on me, i would like you guys to know that i have already bypassed the heater control valve in the engine compartment, coolant is full but i notice at times even at 84 degrees on the climate control, the heater would just randomly blow cold air like its at 65. I would come to a stop and slowly increase the temp from 65 to 82, i usually hear the door motor inside the dashboard when i increase the temp but when the heat goes out the "door" does not operate in the dashboard, i believe it to be some electrical problem as it happens only sometimes, besides the climate control, what could be controlling that climate "door" so i can have it fully functional? if anyone knows about this please please let me know, thanks!
