Galant 2000 heating problem

Hey. I have a problem with my Galant that I had now for few weeks. The heating is working just fine for some time after starting the car but after a while (during longer trips) it starts to blow successively colder air so I have to turn the temperature knob on higher and higher temperature until I reach the maximum of 32 degrees Celsius. At this point it starts to heat at maximum rate which is too hot. So I turn the knob back to 31,5 degrees then it get too cold (I have mesured the temperature, and its about the same temp that is outside - so 7-10 degrees). The temperature in car at this point is usually so around 22 degrees but the incoming cold air makes it very unpleasant. Could it be that the internal temperature sensor wich is installed beside the temperature regulating knob is fooled by the heat that is coming from the head unit of my stereo system? After a while the centner console is beeng heated up by the head unit and the air-conditioner starts to cool. Thats the only logical explanation that I came up to. Is it so and what can I do against it?

Thanx

I think you are on the right track ,The sensor to the automatic climate unit is located just above the adjustment knob on the right of the middle console.This is an intergral part of the climate control unit ,BUT behind the sensor there is a tube which constantly bleeds the interior air to the heater thus measuring the temperature .If this tube has been displaced then the air temp will be static .The heat from the radio/cd player will cause the ecu to think its warm in the coupe ,thus putting on the air con cooling. Solution; Take the radio out and make sure the hose is in place , Its VERY easy to knock it off when fitting a stereo.

You were right! The tube did droop just around blowing air nowhere. After some acrobatic exercises I got it on its right place and I hope that does the job.

Thank you Mate! I will buy you a drink when you visit Estonia! :D
