Go to Step 2

Go to Outside Mirrors System Check

1. Use a digital multimeter (DMM) in order to backprobe across the following appropriate power mirror switch terminals:

•	Oldsmobile LH: terminal F (WHT) and terminal H (LT BLU)

•	Oldsmobile RH: terminal C (GRY) and terminal B (RED/WHT)

•	Buick LH: terminal B (LT BLU) and terminal D (WHT)

•	Buick RH: terminal B (LT BLU) and terminal G (RED/WHT)

•	Pontiac LH: terminal B (WHT) and terminal C (LT BLU)

•	Pontiac RH: terminal F (GRY) and terminal G (RED/WHT)

2. Place the mirror select switch in the position in order to operate the appropriate mirror.
3. Operate the power mirror switch LEFT.
4. Operate the power mirror switch RIGHT.

Does the voltage measure within the specified range?

10-15 V

Go to Step 3

Go to Step 4

1. Use a DMM in order to backprobe across the following appropriate outside power mirror terminals:

•	Oldsmobile LH: terminal F (WHT) and terminal H (LT BLU)

•	Oldsmobile RH: terminal F (RED/WHT) and terminal H (GRY)

•	Buick LH: terminal F (WHT) and terminal H (LT BLU)

•	Buick RH: terminal F (RED/WHT) and terminal H (LT BLU)

•	Pontiac LH: terminal F (WHT) and terminal H (LT BLU)

•	Pontiac RH: terminal F (RED/WHT) and terminal H (GRY)

2. Place the mirror select switch in the position in order to operate the appropriate mirror.
3. Operate the power mirror switch LEFT.
4. Operate the power mirror switch RIGHT.

Does the voltage measure within the specified range?

10-15 V

Did you perform the Memory Mirror System Check?

--

Go to Step 2

Go to Outside Mirrors System Check

1. Set the ignition switch to the OFF position.
2. Ground the memory seat diagnostic connector.

•	The connector may be taped up into the body harness.

•	The module beeps once in order to acknowledge entrance into the mode 1 diagnostics.

•	Refer to Memory Seat Operation in seats for a detailed explanation of the memory seat/mirror module diagnostic modes.

3. Operate the power mirror switch in all directions. (The module beeps once for each received switch input.)
4. Any time a switch is operated and the module does not beep, the module did not receive an input from that switch.

Is there any switch operations where the memory seat/mirror module beeped?
