Your heater motor is probably fine. Pretty sure that circuit breaker self resets.
Here is what I do on all my builds to eliminate that hard cable.
Purchase these parts numbers through summit
VTA-11458-VUS
VTA-11542-VUS
VTA-46103-VUH
You need one of each. The open lug on the heater control switch powers the vacuum valve that opens the heater valve.

Or don't bother w/ remote control for the valve. I didn't get my cable installed right away so just opened the valve manually. I close it some time in April. Fan off ,or on low, or on high, is good enough control for me.

Thanks for posting; I wish I'd seen this before I installed my heater switch. Looks like folks need to wrap that cable stem with electrical tape before installing the switch.
Also, if you're using the Ron Francis harness & fuse box, that 30A breaker will never come into play. You'll blow the 20A fuse in the RF box first. I removed mine.

If you need another breaker I think I still have mine in a box of leftover electrical parts. Didn’t see the point of a fuse and breaker on the same circuit. Your heater motor should be fine but your switch is most likely fried.
Good Luck

I'm with Craig on this one. Having only gone through one winter with the heater (which works great!), I used the fan to control the amount of heat by Lo-Med-Hi selection. I don't have a temp control switch at all on my car. The heater's used a lot when my wife or daughter are in the car (Just used it this morning) and it's comfortable for them. But I do indeed understand your desire to have one.
HTH, Dave

Anybody have good experience with these?
Thanks,

I just installed the heater control valve over the winter, and I love the control it gives over the heat from the heater on the cool nights driving home. Totally recommend it.
It does make the heater line installation a little more complicated depending on your current setup. I mounted the control valve on top on the passenger footbox.

I have a new, never-used heater control if you want it. No wiring, but has the knob, 4 position rheostat, push-pull cable, black covering, exactly like what you show above. I didnt use it because my heater fan is either on or off, and I have a Old Air Products electric on / off / modulator valve.
You can have it if ya want it.
