Anyone know the part number to the blower motor itself? I’ll be getting the resistor from @ToyotaMatt

Rockauto, ebay, etc ... They're all the same unit, made in Canada. They work fine, I have one in my truck. They come with bare leads; you'll have to swap your connector over, or splice, and swap the blower fan.
 
The circuit breaker is another component that can fail, so if resistor and fan motor are good check the CB.
Well, I just put in a brand new motor, fan and resistor and nothing happened. The A/C fuse is fine. Which circuit breaker are you referring to? This big thing to the right of the fuses?

82650-20011 ? Should I replace both of them at the same time? Both ‘power’ and ‘heater’ the same?

The big silver faced breakers to the right of the fuses on the block. I believe the lower right one. Should be a diagram with labels on the backside of the fuse block access door. Use a thin rod to reset the breaker through the small hole on the face of it.

It's identified on diagram on the fuse panel door. The circuit breaker I replaced was some generic one. When I swapped in a good OEM that fixed the issue.

Well, that's outstanding news. I'm retracing my steps but everything is hooked up correctly. My resistor is literally hanging inside of where it's suppose to screw in...when I tried to screw it back in, the screws didn't catch anything...so I'm not sure what to do there. BUT, I'll go ahead and replace both of my circuit breakers with the ones available HERE. Thanks for your suggestions. Let me know if there's a way to retrofit that new resister back into place.

Did you change screws at all for the mounting? I wonder if they got wallowed out at some point? There is a metal shield in the blower housing that mostly surrounds the resistor. I am not sure if the screws also thread into that. Maybe peak inside and make sure that metal shield is still in there?

Peak inside? I can barely access it to take the old one out and put the new one in. I'd love to peak inside but have zero clue how to get a good look at things. My FSM is useless for things like this...

Hahaha, well I meant maybe try and use the phone or something to snap a pic. :D
I'll see if I can find a good pic somewhere.

This is the most aggravating vehicle I've ever owned...it's also my favorite. Once I finish this project, I get to replace universal joints (due to popping into reverse and drive) and I get to upgrade my suspension. But priority for now is A/C, as north Mississippi weather is not conducive to lack of cool air.

You're mental and emotional health is important to all of us. I'll give you $500 for your Cruiser to relieve you of the stress of ownership.

…such a gracious and kind offer. I'm gonna pass on that for today though. I already have about $18,000 invested in her, between parts, services and labor. My plan is to get her back to tip-top condition and pass her on to my children. There weren't many 1990 FJ62s produced for the U.S. and so the likelihood of me getting rid of this unicorn is slim to none.
 
If slamming the vent slide makes fan come back on, then it's not the CB, ... once the CB trips it will stay tripped until you reset it. (reset by pushing a finishing nail into the hole)

Replacing the resistor, the fan motor etc is not going to solve your problem if you have an intermittent issue. Intermittent problems are caused by a loose electrical connection. Or a partially corroded or burned wiring or electrical connection. Check your wiring and electrical connections/grounds for the fan switch, the fan motor, make sure the resistor is fully seated.

I’ve done the nail in the hole thing several times and it’s never done anything. No settings work on the vent and slamming it left or right does nothing either. I’d love for my resistor to be fully seated…and yet, here it is dangling. The top screw is missing because it fell into the hole. Everything is grounded. The wiring to the blower motor may be backward…I’m about to check those.

Ok, I bet you are missing that inner metal shroud. The resistor shouldnt be able to go all the way into the blower housing. Let me go check mine and take a pic.

That sounds like EXACTLY what I’m missing. I was just going to super glue and duct tape that B back into place. The new circuit breakers will be here on the 22nd. Everything else looks good though. The new motor and fan are hooked up snug and the resistor is connected correctly but there is definitely no shroud.
