I have a 1981 Corvette with fully functioning stock A/C. For reasons to lengthy to discuss, I want to convert (or modify) the Heater A/C Control from vacuum actuated to electric. Is this possible, and if so, is it possible with limited parts replacement and a small brain? I understand I would need a modern electric heater control panel assembly. Thanks in advance for any help, as I may be the forum's village idiot. J.D.
This is not a practical undertaking. The entire system is designed to be electronically controlled, blend doors, etc. There are also sensors to keep the unit from freezing and it is typically tied to the engine computer, too.

An electric vacuum pump could be fitted to run the system instead of vacuum from the engine.
Thx for the replies. If an electric vacuum pump can be used, where would one obtain said pump? And, what kind of control panel would be used? In a nutshell, the motor is 500 HP and there is little to no vacuum available. I am converting the headlight and wiper systems to electric, and would like to do so with the heater controls. Additionally, I am custom fabricating a replacement console and gauge cluster, and trying to relocate the A/C-Heater Control panel and stereo to the glove box compartment. So, that's what I'm up to. Any additional info is greatly appreciated. Again, thx in advance. J.D.
There have been several alternators made with vacuum pumps. Delco & Hitachi put them on the back, Nippondenso runs the vac pump on the front behind the pulley.
Many of the eurotrash diesel cars have vacuum pumps. Probably the most straightforeward solution, just replace the alternator. There should be an alternator that will work. The little Denso hairpin puts out about twice what your OEM alternator puts out, and is smaller.
