Well, the auto/marine electric shop is looking into my heater motor. Hoping they can fix it.
I cleaned up my heater valve by soaking it all day in Evapo-Rust, and it cleaned up pretty nice. I could move everything by hand. But I put it in a pan of hot water and tried the lever in the position with least spring pressure applied, and the valve didn't move. Seems like the brass temperature-expansion disc is toast. So now trying to figure out what to do next. Also noted that the rubber seal was in bad shape and it would probably be leaking any day now if I put it back in.
The other thing I did (bad) was trying to free up the heater control cables, two of them broke, up at the control lever attachment point. Has anyone ever been able to replace those without taking out the dash? I saw this source for them on an earlier post, but I have to figure out what the lengths are first, I guess.
Bowden Heater Control Cables from NAPA Finally, the one wire that I know I have to replace in the dash is the wire to the backup lights. Wow that is way up there, maybe I will be able to reach that without taking out the dash.
