What Does the Power Mirror Adjust Switch Do?
The power mirror adjust switch serves as the driver-side control interface for your vehicle's electric side mirrors. Mounted in the driver's door panel, this switch allows you to:
- Select which mirror to adjust (left or right) via the selector toggle
- Move the mirror glass in four directions (up, down, left, right) using directional controls
- Send electrical signals to the mirror motors that physically reposition the glass
The switch contains internal electrical contacts that close circuits when you press each direction. Over years of use, these contacts oxidize, wear down, or break, resulting in mirrors that won't adjust or only work intermittently. The APDTY 012237 restores this critical visibility and safety function with factory-equivalent operation.
What Are the Symptoms of a Failing Power Mirror Switch?
A worn or faulty power mirror adjust switch typically produces one or more of these symptoms:
- Mirrors don't respond when you press the adjustment controls
- Intermittent operation—mirrors work sometimes but not others, or only in certain directions
- One mirror adjusts but the other doesn't when you toggle the selector
- You must press very hard or wiggle the switch to get any response
- Clicking or loose feel in the switch mechanism with no mirror movement
Before replacing the switch, verify that both mirror motors still function by swapping the left/right selector position. If neither mirror moves in any selector position, the switch is the likely culprit. If one mirror never works regardless of selector position, that mirror motor may have failed instead.

How to Replace the Power Mirror Switch: Installation Overview
Replacing the power mirror adjust switch is a straightforward job most DIYers can complete in 15–30 minutes with basic hand tools. General procedure:
- Disconnect the battery negative terminal and wait 2 minutes to allow any residual electrical charge to dissipate
- Remove the driver door panel—typically held by several Phillips screws around the perimeter and push-pin fasteners; consult a service manual for your specific model
- Locate the mirror switch on the removed door panel (usually near the front upper corner)
- Disconnect the electrical connector from the back of the old switch
- Release the retaining tabs or clips that hold the switch in the door panel bezel—some designs snap out, others may have small tabs you depress
- Install the new APDTY 012237 switch by snapping it into place until it locks securely
- Reconnect the electrical connector—you should hear or feel a click when fully seated
- Reinstall the door panel, ensuring all clips and screws are secure
- Reconnect the battery and test both mirrors in all four directions and both selector positions before final assembly
Safety note: Always disconnect the battery before working on electrical components to prevent shorts or accidental airbag deployment. If you are uncomfortable working with door panels or electrical connectors, consult a professional technician.
Frequently asked questions
Will APDTY 012237 work if my interior is black instead of gray?
No. This switch is molded in gray plastic to match gray interior trim. If your vehicle has black interior, order APDTY-012235, which is the identical switch in black color. The color is cosmetic only, but mismatched trim looks unprofessional once installed.
How do I know if my switch is bad or if the mirror motor itself has failed?
Toggle the switch to the opposite mirror. If neither mirror responds in any direction when you move the switch, the switch is likely faulty. If one specific mirror never works regardless of selector position, that mirror's motor may be the problem instead of the switch.
Does this switch fit the right (passenger) door or only the driver door?
APDTY 012237 is designed for front left (driver door) installation only. It controls both mirrors from the driver's position. There is no passenger-side mirror switch in these GM truck models—all mirror adjustment is done from the driver door.
Do I need any special tools to replace the power mirror switch?
Most installations require only a Phillips screwdriver, a trim panel removal tool (or sturdy flat plastic pry tool), and possibly a socket set for door panel screws. No specialty electrical tools or programming are needed—this is a direct plug-and-play replacement.
The APDTY 012237 power mirror adjust switch delivers a cost-effective, factory-equivalent solution for restoring mirror control in 1998–2005 GM trucks and SUVs with gray interior trim. By replacing worn-out internal contacts and mechanical components, this switch eliminates the frustration of mirrors that won't adjust, improving both safety and convenience. With direct-fit connectors, straightforward installation, and OE-quality construction, the 012237 gets your mirrors working again without the dealership markup.
