Little Things Will Get You

I replaced the heater in my '74 last winter with a rebuilt heater and everything was great until this summer when I noticed I couldn't turn the hot air off in the 90 degree weather we were having. It was like 97 outside and inside my car couldn't have been less then 120. I finally finished my list of excuses for not fixing it and figured it would take me a day or two to get everything adjusted right and the heater valve working. Unfortunately it took much longer and about had me tearing what little hair out that I have left. It turned out to be a custom bracket that someone made and screwed into the case to reinforce where the heater valve mounts. The screw they used was too long and interfered with the operation of the heater flap inside the box which kept the heater valve from closing all the way. Cut the screw off a little bit and it went back together and worked like it was always meant to. So after 4 days, and several new parts all I had to do was cut a screw off.

FYI, later 2002s (perhaps all squarelights, but I'm not absolutely sure on this) have a small hole drilled in the heater valve that allows a small amount of circulation regardless of whether the heater is set to cold or hot.  This is to allow a limited flow year-round to keep sediment from forming in the heater core.

It was interesting because the vent flap was hitting the screw, the cable to the heater valve wouldn't throw the correct amount therefore leaving it partially open. When I filed the screw down a little to where it was no longer obstructing the heater flapper to close completely it also allowed the heater value to completely close.  While I was in there I cleaned up the heater value and checked it out. Everything seems to be working fine now.
