Figure 15.59. Location of exterior rearview mirror control components: 1 – electric motors located in the mirror housings; 2 – ECU unit located on the front passenger side; 3 – ignition switch; 4 – switch for adjusting the position of the outside mirrors; 5 – driver's side fuse box
To adjust the position of each exterior rearview mirror, two electric motors are used: one for adjustment in the vertical plane, the second - in the horizontal plane (figure 15.59).
The switch has a selector that supplies voltage to either the right or left mirror.
Check the drive of the outside rearview mirrors as follows.
Turn on the ignition without starting the engine. Lower the front windows and alternately turn the mirrors in the vertical and horizontal planes, listening to the sound of the running engines.
If the motor is running but the mirror does not move, the mirror drive mechanism may be faulty. Remove and disassemble the mirror to determine the cause of the malfunction.
If the mirrors do not move and you cannot hear the motors running, check the integrity of the fuse.
If the fuse is good, remove the switch from the instrument panel and check its condition.
In accordance with the electrical diagrams, check the reliability of the connection of the mirror wires connected to the ground.
If the mirror still does not work, remove it and check the power supply to the mirror.
If there is no voltage even in one switch position, check the electrical circuit between the mirror and the switch.
If voltage is present in all operating positions of the switch, remove the mirror and check the functionality of the electric motors by connecting them with additional wires to the battery. If the motors do not work, replace the mirror.
