Q: How to Troubleshoot and Repair Electric Rearview Mirrors in Buick Enclave,Chevrolet Traverse and GMC Acadia?
A: The electric rearview mirrors in vehicles use two motors to adjust the glass. Some vehicles also have memory mirrors that are connected to the power seat memory unit and the Body Control Module (BCM). To troubleshoot any issues with the mirrors, start by operating the mirror control switch through all functions while listening to the sound of the electric motors running. Additionally, check the ground connections and test the wires at the mirror for voltage. If there is no voltage, check the circuit between the mirror and control switch for any opens or shorts. If there is voltage, remove the mirror and test it off the vehicle with jumper wires, making sure to use the correct leads and if the mirror fails this test, it should be replaced.
Q: How do you remove and install outside and inside mirrors on Chevrolet Traverse,Buick Enclave and GMC Acadia?
A: To remove the outside side view mirrors, start by removing the door trim panel and molding. Then, disconnect the electrical connector and remove the mirror fasteners. For installation, simply reverse the removal process. To remove the inside side view mirror, first remove the mirror cover fastener. If equipped, disconnect the electrical connector from the mirror. Then, remove the setscrew located at the base of the mirror stalk. Slide the mirror upwards to remove it from its mount. If the mounting plate has come off the windshield, you can use adhesive kits to resecure it. Follow the instructions included with the kit, making sure to position the flanged part of the mount away from the glass and the narrower part pointing up.
