DESCRIPTION
One mirror control switch adjusts both left (driver side) and right (passenger side) mirrors. Mirror select switch setting determines whether left or right mirror is adjusted.
OPERATION
Each power mirror assembly contains 2 reversible motors: an up/down motor and a left/right motor. Mirror control switch reverses polarity of motor circuit to change direction of mirror movement. Each motor contains a self-resetting circuit breaker, which opens when mirror reaches its mechanical limit of travel.
TESTING
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION Section before disconnecting battery. |
Before performing following tests, ensure circuit ground, circuit harness wiring and circuit fuse are okay. Also, ensure all circuit connections are clean and tight.

- If test light comes on, check for poor connections at Light Green wire terminal and Yellow wire terminal of left outside mirror drive unit connector. If connections are okay, replace left outside mirror drive unit.
RIGHT MIRROR UP/DOWN POSITIONS DO NOT OPERATE (LEFT/RIGHT POSITIONS OPERATE NORMALLY)
- Place mirror select switch in right position. Toggle mirror position switch between up and down positions. With mirror control switch connector still connected, using test light, backprobe between terminal "E" (Yellow wire) and terminal "F" (Light Blue wire) of mirror control switch connector.
- If test light does not light, check for poor connections at Yellow wire terminal and Light Blue wire terminal of mirror control switch connector. If connections are okay, replace mirror control switch.
- If test light comes on, toggle mirror position switch between up and down positions. With right outside mirror drive unit connector still connected, using test light, backprobe between terminal "D" (Yellow wire) and terminal "C" (Light Green wire) of right outside mirror drive unit connector.
- If test light does not light, check for open in Yellow wire or Light Green wire between mirror control switch and right outside mirror drive unit. Repair or replace as necessary.
- If test light comes on, check for poor connections at Yellow wire terminal and Light Green wire terminal of right outside mirror drive unit connector. If connections are okay, replace right outside mirror drive unit.
RIGHT MIRROR LEFT/RIGHT POSITIONS DO NOT OPERATE (UP/DOWN POSITIONS OPERATE NORMALLY)
