ELECTRIC CLIMATE CONTROL

1997 Volvo 850

Air Conditioning problem
1997 Volvo 850 Front Wheel Drive Automatic 179000 miles

My Volvo 850 GLT has a intermittent AC cooling problem. In the AUT selection the AC will cool great and after a few miles will go warm. It has fresh Freon and has no leaks. If I turn it off and let it stay in the off position and recycle both the AUT switch and the AC switch it will begin working again for a while and repeat the same thing. Some time ago I noticed that the air valve doors under the dash would also not open so I suspect this is all tied together to the ECC.
