so a couple of months ago my passenger power window was actin up on me, it would work for awhile and then die, if you pound/bang on it, it would work again for a few seconds. so the other night i replaced it with a good know working one, plugged it in and found out it was moving. so i did a hot test by directly powering it by the battery, both of them worked great but slow. then i opened the “good known working motor” (the one with the manget/motor) up and then put it back together after fighting with it to go back in. plugged back up on the harness, works all the time now, but making a loud noise now. just wondering why the motor only gets power now and then only. all fuses and relay seems fine, since its working good now.
