Blower/Heater circuit breaker tripping

Need to update since I forgot about this thread. For whatever reason the cleaned up contacts and NEW OEM breaker didn't solve the tripping issue. I put a jumper in with a DC clamp meter and measured no higher than 16.5A on the circuit with front and rear on max and the AC running. Needles to say, perplexing and more than a little irritating.

So I fashioned a jumper with an in line 30A fuse and installed it. The wire doesn't even get warm to the touch (even after several 3+ hour drives in high heat with everything running last summer), and the fuse hasn't blown yet.

Yeah I never measured anywhere near 30amps when my circuit was blowing. It was definitely a weird issue!
 
Unfortunately no, it's a Toyota specific part. Did you happen to hang on to your old motor? I'm trying to collect junked motors for some experimenting I want to do with restorations and upgrades for more long term service.
FYI toyota Matt sells denso replacement fan motor, same as stock except for the plug, which is on a pigtail now.

He does. It's a Denso (Toyota's OEM) that does work as a viable replacement for the 12V 6x series. AFAIK it's still being actively produced to so at this point it's the best option for a plug n' play replacement. FAR superior to the 4 Seasons/VDO that parts stores carry. Moves more air and considerably quieter, as a factory blower motor should be.

I still intend to experiment with a brushless upgrade that'll use an entirely custom airbox which would accommodate a cabin air filter. Driving my 62 around the wildfires in eastern WA these last few days with an AQI of 300+ made me realize just how much better it is to have a cabin air filter with these conditions. It was literally raining ash at my house just yesterday! Combined with the dense smoke and eerie silence, stepping outside looked like a scene from the Silent Hill movie.

Edit: Forgot to mention that there's also a Siemens unit that's a physical match. Not sure what actual factory it's made in (could be the same as the 4 Seasons/VDO or could be the same as the Denso. Could even be in a factory that's exclusively Siemens; just no clue) but I intend to get one and take it apart to compare the internals between a Denso unit and a VDO unit. Would be nice if it's comparable to a Denso unit.
