Blower motor not working

bought a new motor and regulator to replace the old ones but that seems to not be the problem! I’ve checked the wiring diagrams and tested them, even did a bridge which turned on the blower! Even put direct power to the motor which turned on as well! What seems to be my problem? Please help!

Sometimes it is easier to pay the dealer for diagnostics and save yourself a lot of time and trouble.

ok I fixed the problem! It’s potentially the white wire that is connected to the control, the control is the problem, whenever I reduce the speed of the fan it turns off, that’s what my problem seems to be, if anyone has a control they’re not using let me know!
