1969 Buick Electra - automatic climate control question

Recommended Posts



I have a 1969 Buick Electra 225 with automatic climate control.


I am wondering if anyone knows of where I might find a thermostatic vacuum regulator for this system. I know that the part is obsolete so I would have to find one either on a donor car or find an old one uninstalled. 

I’m wondering if anyone would happen to have one of these or have any idea where I might be able to get one. 

I think I will attempt to rebuild mine considering it is not working but I just thought I’d ask in the meantime.


Attached is a photo of the Thermostatic vacuum regulator.

Jakob, you might get a better response here https://forums.aaca.org/forum/57-buick-post-war/ .


Lot of people there have parts books and can look up the ATC regulator part number for you.


One thing that kills me about GM cars with automatic temperature control is that no two Divisions did it the same way and there are few to no common parts between Divisions.
