Have already searched thru previous posts to solve problem with no luck resolving the issue. Am looking for specific help.
I have a 96 Buick Park Ave. with a 3800 engine, and automatic climate control. During some recent work that was done on the car the battery was disconnected without shutting off the ACC. now one side blows out hot the other cold. Seems to work correctly for a very brief period, then temp starts to blink then blend doors position themselves to blow out hot on drivers side and cold on passengers's side, the back vents blow hot and defrost cold. Have tried a couple different procedures with no effect, not sure we are tring the right thing.
Thanks, Mrs. Journeyman
