hello
to all
I have a 1992 corvette convertible 29 K miles . the problem I'm having now is. I have no control over the... Heater and AC control head ..the only button that works is the rear defogger .no other button on the control head works ..the heat is blowing but there is no control over it .
I have replaced the Heater and AC control head 2 times now and it dose not solve the problem .
I have the factory service manuals from GM .
I have check all grounds and voltage going to control head all OK I can get a reading on control display if I hold down auto fan buttons at the same time but it has know effect on anything .
Have no read out on control head display -- can not get AC .can not control fan .blowing heat only . I could use some help thank you
