Can the HVAC controls on a base trans am/firebird (two sliders) be converted to the GTA HVAC controls (all buttons)? What all would need to be replaced besides the unit? Also I think mine has gone out, what is the most common cause of death? I slide mine and hear hissing and noises like it wants to work but nothing is blowing out of the vents on any setting. Thanks.

 

I don't really know how to help you...but I had an HVAC question as well; where is the vacuum hose hooked to in the engine bay? Anyone?

As far as your question; what "GTA" HVAC control are you talking about? The ones in the 88 or so GTAs that came with the digital dash and stuff?

 

good question, great idea

Someone must know and/or have pics/diagrams of the digital HVAC control unit.
How does it hook up
someone.....
