Strange Climate Control Issue
The reason I say climate control is that it affects everything from heater to vent to A/C.
It doesn't matter if I'm in town or on the interstate. When the engine is under load, the air switches to the defrost vents. It doesn't matter what setting I have it on, it still does it until I ease up on the gas pedal and then it blows air normally on whatever setting I have it on.
For example, I will be cruising at 75 MPH on the interstate with the cruise control on. If the road is flat or downhill, the A/C, heater, vent, etc. blows normally on whatever setting I have it on. However, when I start to go up even a slight incline, the gas pedal goes further down to maintain speed and the air immediately switches to the defrost vents and stays that way until the road is flat or downhill again and the cruise control eases up on the gas pedal. It happens with or without cruise, downshift or no downshift.
To make a long story short, if the engine is under increased load, the air blows only through the defrost vents until the engine load is decreased.
Any idea what might be causing this?
