Blower motor suddenly stopped working upon replacement

Hey everyone, I need some help and it's actually urgent (Not dangerous). I replaced my chirping motor with an O'Reilly 65 dollar one. Worked but not pleasantly due to noise and vibration. So I greased my original, took off the cover and those spring-loaded copper connectors, and blew it all out with an air compressor. I did not disassemble the fan and motor and I did not clean it with anything wet, like many here have done per the repair threads here on TW. The grease stopped the squeaking by a hand test so I was excited to try it out the next day.

I tried to install the greased original today after work and it did nothing, blew only on high for a split second, then stopped and the connector was really hot. Assuming I got something wet in the original, I put the cheapo back in and it also did not work.

This leads me to believe i did something to the connector in the time I swapped the motors. Someone please shed some light on this as I work in a refinery as well as commute in 90+ degrees and 75+ humidity (aka sweat city)

Any ideas?? I leave for a work trip Wednesday and only have tomorrow evening to fix it. Thanks all.

Note: the connector getting hot and the fan working for an instant leads me to believe the harness IS getting power. Please help!

Update : 2 hours after the incident I read some solutions online and hitting the blower did nothing, the fuse is not blown, BUT when I switch the A/C to a different setting (any of them) and used any of the speeds, it would make an electric actuation noise and "buzz" or "whirr" for a little bit then quit but the fan itself did not move. It restarted consistently with each chang of setting. This gives me a little hope that the wiring is alright. Both motors can't be broken, especially since the O'Reilly motor has been working fine and was only unplugged for a few minutes.

 

Bump, anyone?

I didn't realize TSBs offered repair instructions for those not covered under warranty. That's good to know. But if mine no longer operates on high, either, doesn't that mean there is another problem?
