I have an 89 Riviera with a heater problem. One day I couldn't control the heat , couldn't turn it off. The following day the heat was gone. Air cond. works. I checked under the hood and all vacuum lines seem to be intact.I really don't want to dig into the dash without some info on it.
I hope that someone can give me some info on this system or point me to a place with information on it.
Thank you
Glenn
