66 Cuda HVAC control problems

That switch looks similar but not sure. I will look in my box of parts to see if I kept the old one and compare. Yes the vacuum connector is like that. The pins are brittle and break, resulting in leaks. Mopar kept similar design for many years.

I looked and I think I remember tossing it after taking it apart, it was beyond my repair, I seem to remember erosion in the electrical switch parts, and other wear. Perhaps someone will know if a later switch will work. I seem to remember it is a chore to replace. I have big hands, and needed to pull the glove box liner, radio and lower A/C vent system to work. Those are all easy to do, so not to worry. I m old enough not to be flexible, nor see well under dash. I think the choke type cable on the temperature slider gave me grief.

About the vacuum canister, my car does not have one, and A/C works fine. I have seen 66 B'cuda cars with power brakes, and the vacuum canister mounted on the drivers side near the washer reservoir.

I just spotted a used switch: http://www.ebay.com/itm/1960s-chrys...Parts_Accessories&hash=item2eca5fedbe&vxp=mtr

This one calls out 1966 - 1973: http://www.ebay.com/itm/Mopar-NOS-A...Parts_Accessories&hash=item5654942fdf&vxp=mtr
