Default Blower motor slowly stopped last night. its 7 mos old

hey all,

2004 WRX Wagon
obviously manual (three dial) HVAC control panel under the radio

So back in July 2018, my '04 WRX Wagon's HVAC blower motor just stopped. Was running errands all day, A/c cold and blowing, no issues. Got home, went inside. 4 hours later go out to run to Wally World for the Mrs. and fire up the car and get 1/2 block and realize the blower motor isn't working... Went old school on it and gave the blower motor hanging below the glove box a couple "love taps" with a screw driver handle. It started working for about 20 min. then stopped completely.

Pulled the cabin filter cover and vacuumed out a metric crap-ton of stuff out. blower survived about a week longer. Then finally seized. Rockauto, $165 later.. ouch. blower motor+partial case and resisitor on the door step. All in the car in under 30 minutes. All good to go..... Until last night.

I was driving home from Omaha, NE to Dallas and I noticed that the fan was slowly, like over 4-5 hours, dying off. By the last hour from Oklahoma border to home, no fan at all.

Today I had a little time, unplugged the blower fan and hit it with 12v from a drill battery. WOW! the resisitor pack really throttles the fan back in these cars. But motor is fine. I checked the case, no debris. Filter was a tad grimy so I swapped it . I had another resisitor, swapped that, nothing.

DVOM on the resisitor:nothing. No 12v.
DVOM on Blower motor wiring: no 12v

pulled console and radio, and pulled up the (2) plugs off the manual HVAC/climate control panel.

white plug with 12ga wires looks hot and scorched. But 12v present going in.

So looks like the HVAC manual control panel. How in the living do you get the cables off the control panel under the radio? or do you have to undo them at the heater bocx connection and swap the panel cables and all?

I've searched google, youtube, here, 2.5rs, iwsti, etc etc etc. But of course I have missed that one post that shows me step-by-glorious step..

Please direct me or talk me through it.

finally Autozone is good for something... to remove the manual 02-07 hvac control panel the cables are disconnected at the HVAC box.

control unit and cable come out as a unit through the radio opening.

Im working in San Antonio tomorrow and there are no less than 15 yards on my way home with controlers from '06-'07s which should have fewer miles for under $40. I'll stop and grab a complete controler and cables that way I can take it out myself the first time and see what's up.
