Huh. I got the motor yesterday. What the seller didn't tell was that the connector was melted and someone had did a bad job fixing it. At first i thought there was just the molten connector there with terminals at the other end of the wires, but no. He had removed the PCB and soldered the wires straight to the pins of the female connector and then filled the connector with some sticky black stuff
And of course it was all done by someone who should have never touched a soldering iron...
Since i didn't want to cut my good connector i removed the PCB again and swapped the 10-pin connector from my dead motor. Miraculously it started to work, well at least electrically... Turns out the bearing was bad or something like that, as the motor was shaking while speeding up and then stopped until i restarted the A/C. I oiled it as well as i could without removing the PCB again and managed to get it working somehow. It still stutters and stops sometimes when starting up and especially when i raise the speed manually too fast. I hope running it will lubricate it better but at least it works somehow while the A/C is in auto position...
While there was smoke coming from my air vents when the motor broke down, i guess there was even more of it coming from my ears yesterday while fixing it
Luckily my summer vacation starts TODAY
