1165A1, Heater Thermotion Switch/ control

[aconway]

Has anyone had to replace their heater hose / thermo switch? I can't find anything on it. id like to know how you test it. Mine is a 24v switch , shows on the sticker. But, it doesn't seem to move however, if I take it loose from the arm it attaches to I can move the lever and get heat.
Anyone have some helpful info id appreciate it.

I just replaced one recently with a small brass ball valve and brass barb adapters from home deeps. The originals seem to all be deteriorated or problematic in some fashion.

Thanks, and I have thought about just going to a manual valve, but was curious first if I can find the issue on why the factory valve/swith isn't working.
just not sure how to see if mine doesn't work.
I will do something like you did though if needed .

When you take yours out and look inside you will see a crumbly mess and gain understanding. Had a guy with 60+ humvees to his credit show me a recently removed valve and it enlightened me. I went and replaced the one in the unit I was futzing with and sure enough with that ball valve shut I had cold A/C out of the front unit instead of luke warm

I just replaced mine a few weeks ago as well with a ball valve. To me the cost of a OEM replacement wasn’t an option. Also the ball valve Is less restrictive than the oem setup in my opinion. I just used the ends off the old solenoid connectors and made plugs to cap off the electrical connectors.

You could also use the earlier cable controlled valve, then if you wanted to you could install a cable to control it, VERY handy in S TX where it can be in the low 50s in the am and high 80s in the afternoon.
