IIRC someone has used Dorman window lift motors before. Just picked one up for the front left door but the screw holes are not threaded and the connector does not fit into the factory harness even though they included three different wired connectors. I can tap the holes and use the connector from the original motor, but then if it turns out not to be the problem I can't return the motor once it's been cut up. So, did I get a bad part or do they all come this way??
