2007 H3 Heat/AC Temp Adjust Problem
Last month I had a new engine installed (Thank God for the warranty), and my Hummer runs like a new one again. The only problem I have is with the Heat/AC Temperature adjust control. If the AC is ON, and the **** is set to the coldest position (full CCW), it works fine. If you turn it one click or 10 clicks or fully CW, the AC goes from cold to full heat. There is no gradual increase.
If the Heat (or defrost) is ON, there is no temperature adjustment. It is full hot or nothing.
Did the mechanic reinstall something wrong during the engine replacement?
Please don't waste your time writing and tell me to take it back to the dealer. I live 150 miles away and missing a days work isn't possible for me right now.
I'm hoping this is a simple fix. I just need a place to start looking.
Thank you,
Paul

Thanks for the tip drtom. I will research it.
I didn't mean to sound demanding, that's why I said "please". So my apologies. There is always some dumbass out there that thinks it is funny to say "call the dealer".
