The electric side-view mirrors can be adjusted up-and-down and left-to-right using a driver's side switch on the left door trim panel. Models with factory-installed dual power mirrors feature a heater grid behind the mirror glass to clear fog, ice, or snow, and if a heater grid fails, the entire mirror must be replaced. The heater grid switches and heated mirror system indicator light are part of the heater/air conditioning control panel on the dash, and if any of these components fail, the entire assembly should be replaced. The heated mirror relay is found in one of the fuse and relay boxes. The power mirror control switch includes a LEFT-RIGHT selector switch to direct voltage to the desired side-view mirror. With the ignition in the ACC position, roll down the windows and operate the mirror control switch for both mirrors while listening for the sound of the electric motors. If the motors are audible but the mirror glass does not move, the drive mechanism inside the mirror is likely defective, requiring a mirror replacement. If there is no sound from the mirrors, check the fuse in the fuse and relay boxes. If the fuse is intact, access the back of the mirror control switch by removing the door panel without disconnecting the wires, then check for voltage at the switch with the ignition ON. If voltage is present, disconnect the switch and test for continuity in all operating positions; if continuity is absent, replace the switch. Reconnect the switch and check the wire going from the switch to ground; if the mirror operates normally with a jumper wire connected to ground, repair the faulty ground connection. If the mirror still does not work, remove it and check for voltage at the mirror wires with the ignition ON and the selector switch in the appropriate position, ensuring voltage is present in each switch position except the neutral position. If voltage is absent in any position, inspect the wiring between the mirror and control switch for issues. If voltage is present, test the mirror off the vehicle with jumper wires and replace it if it fails the test.
