Q: what rise could be wrong with the passenger side headlight motor besides needing a new gear?

asked by on

The passenger side headlight stopped working and took out the motor to replace the gear, while out the motor would run longer then it should. We replaced the plastic gear and after reassembling everything the headlight worked but still made a loud grinding type noise worse in the on position and ran at least twice as long as it should. After maybe 10 times trying the headlights it wanted to catch and wore the gear. Is it motor or module. We are also having issues with factory alarm setting off almost everytime we open the door so didn't know if it could be related.

My car has a manual transmission.

The motors have a built in limit switch that will signal when the motor is up or down. If the motor keeps running going up or down, the the limit switch inside the motor circuit is bad and a new motor is needed. If you want to have this checked firsthand, a technician from YourMechanic can come to your car’s location to diagnose the headlight.
