Re: Photo of original heater control valve install?
BTW, anyone care to venture a guess as to why my 1970 had a 2-port head when I got it? I thought they were all 3-port 1970 and later.
The water control valve was gone from the truck, so maybe someone swapped a 2-port in and it wasn't compatible with the 1970 water valve, so they had to remove it?

I have a 3 port vacuum switch on my AC controls, I purchased a new "4 Seasons" heater valve which is "closed with vacuum applied". This appears to be incorrect with the 3 port switch as I need a "open with vacuum applied" Anybody have a correct part number? Thanks! |
