Most automobile electric rear impression mirrors come equipped with two humble, frank in fashion, reversible motors. A humble “delectation stick” or containment switch is used to function the mechanism that moves the mirror into contrary angles. Propel the rear view mirror control switch and listen for the motors running. If you can hear the motors, there is a problem with the drive mechanism inside the mirror housing. Most mirror assemblies have to be replaced as a unit.
Instructions
1. Turn the ignition switch on nevertheless bring about not launch the engine.

5. Unplug the switch and check it for continuity in its different positions using a multimeter. If there is no continuity, replace the switch.
6. Check the control switch ground connection using a jumper wire. With the control switch off its mounting panel and wires connected, hook one end of the jumper wire to the switch ground connector and the other end to a good ground on the vehicle.
