Hello,
Thanks for the help. I have a curious situation with my 99 oldsmobile intrigue. In the summer time the Dual Thermostat (DT) blows hot air. In the winter time, it simply blows cold. Even putting the control on 90, it simply engages the AC compressor and blows cold air. It's almost like electrical like the computer is "confusing" outside (external) temperature with cabin desired temp. Any ideas?

Thanks!

because this si automatic temp control a pro will have to scan it to find what is messing up causing your problem. it may be an actuator but must be scanned first.
