NA Climate Control heat/cool flap problem
A mates NA Fairlane only delivers cold air to the vents, cooling systems is all ok, heater tap works fine etc.
A self test on the CC doesn't return any faults, and when its testing, a electric motor noise can be heard which i'm pretty sure is the hot/cold flap motor recalibrating.
So, I can only think that the motor has become disengaged from the flap in someway, anyone had any experience with this and could shed some light on the problem?
Many thanks for any help
