Hi All,

Wondering if anyone else has had this problem and what the fix for it was.

My car blows cold air out the driver side, I can't get heat out of it no matter what I do. The passenger side works fine though.

So, my first thought is that it's the motor (actuator) that opens and closes the flap for the heat.

But, when I start the car in the morning it's cold obviously. Usually the hvac fan will stay off until the car warms up enough and then it will start blowing heat. What's happening now though is that the car starts blowing as soon as I start the car.

I can't quite figure out why this would be happening. If I jack the temp on the driver side way up or way down it starts blowing like crazy so it seems the HVAC computer itself is ok.

I'm thinking maybe it's the thermometer? If the termometer stopped working would it default to some base temperature? The outside temp these days is around 50, I have my hvac set to around 75 degrees. That would mean that the default would have to be below 50 for it to think that the car is too warm and it needs to fire up the fan right away then no?

What I've had to do is leave it on vents only, close the driver side vents, and point the passenger side vents towards me.

Thanks to anyone for help,
Robin.

Had a car once that did something similar. The AC needed reprogramming. The program didn't open the valves for the air correctly.
