I have an interesting problem.

(not sure if this is relevant but I figure too much info is better than too little) I got into a rear end accident last november and have fixed everything (so i thought) but now that it is warming up again, I realized that the defroster and the floor heater are always blowing out HOT HOT air. I can control the hot/cold of the vents with the dial in the center of the dash however the floor and defroster are blowing out hot air continually.

Has anyone seen this before?

Anyone have any idea what could cause something like this?

Can someone tell me what the Air Flap Actuator does?

Is there always hot coolant in the heater core?

Is it possible that the air coming out of the vents is always being pushed through a hot heater core instead of recirculating inside or outside air?

Is there a valve that opens and closes to allow hot coolant to enter the heater core when needed and not when not?

Is it possible that the temperature sensor or the dash unit that shows the temp settings and fan adjustments etc is faulty and all that needs replaced?

Thanks all for any help you can offer.
