Automatic Inside Dimming Mirror
Description ('02-04 Model USA)
The automatic dimming has a front-facing lux level sensor, a rear-facing lux level sensor, and a control unit. The control
unit receives signals from each sensor. Based on the difference between the two lux levels (the light outside the vehicle
and the light from the headlights of the other vehicle, etc.), the control unit controls the electro-chromic gel to reduce the
glare. This dimming function is canceled when the transmission is in reverse, or when the automatic inside dimming mir-
ror switch is turned OFF.

Test/Replacement ('02-04 Model USA)
NOTE: Before testing, check the No. 13 (7.5 A) fuse. No.
7, 10, 11, 13, 14 and 15 terminals are OnStar switches
microphone power, ground and signal lines.
1. Disconnect the 16P connector from the mirror.
2. Check for voltage between the No. 12 terminal and
body ground with the ignition switch ON (II).
• If there is battery voltage, go to step 3.
• If there is no voltage, check for:
— an open in the wire, or
— poor ground (G401, G402).
3. Check for voltage between the No. 16 terminal and
body ground with the ignition switch ON (II) and
A/T gear position in
• If there is battery voltage, replace the mirror by
removing torx screw.
• If there is no voltage, check for:
— an open in the wire, or
— faulty reverse relay, or
— faulty transmission range switch, or
— faulty diode.
