Re: Questions: Heater Control Valve, Blower Motor, 1953 Cavalier (also progress update)

Good news: Buchannan Auto Electric (Oakland, CA) said they can repair the heater motor.
I took my valve apart and verified that the little copper expansion disc is not responding to temperature, probably it has a leak. Also I noticed it had what looked like a clip to seal off where the capillary tube was. It may be a project for me to fix over time, from what I understand it wasn't filled with any fluid, just sealed. From what Danchuk says, in 1955-56 Chevy replaced the capillary tube with a clip, maybe this is the same clip.

I also found a valve from Packard Seattle, will see how that one works, and good to compare with whatever I can do to repair mine over time.
