Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition to OFF position and remove key
3. Disconnect negative battery terminal and wait 3 minutes for airbag system capacitors to discharge
4. Ensure sunroof is in fully closed position before beginning work

Procedure

1. 1

   Remove overhead console trim
   Using plastic trim removal tools, carefully pry down the front edge of the overhead console cover near the sunroof switch. Start at one corner and work around the perimeter. There are 4-6 plastic clips holding the trim in place. Pull the assembly down gently once clips are released.
2. 2

   Disconnect dome light connector
   Locate the dome light electrical connector on the back of the overhead console trim. Press the release tab and pull the connector straight out to disconnect. Allow the trim piece to hang down for access.
3. 3

   Remove sunroof switch electrical connector
   Locate the sunroof switch connector on the back side of the switch assembly. Press down on the locking tab while pulling the connector away from the switch. The connector has a positive lock that must be disengaged.
4. 4

   Remove sunroof switch from trim panel
   The switch is held in place by two small tabs on each side. Using a small flathead screwdriver or trim tool, gently press the release tabs inward while pushing the switch out from the front of the trim panel. Work one side at a time to avoid breaking the tabs.
5. 5

   Install new sunroof switch
   Position the new sunroof switch at the opening in the overhead console trim. Align the switch carefully and press firmly until the retention tabs click into place on both sides. Verify the switch is seated flush with the trim surface.
6. 6

   Reconnect electrical connectors
   Connect the sunroof switch electrical connector first, ensuring the locking tab clicks into place. Then reconnect the dome light connector, pressing until you hear the lock engage.
7. 7

   Reinstall overhead console trim
   Align the overhead console trim with the headliner opening. Start at the rear edge and press upward firmly at each clip location until all clips are fully seated. Verify the trim is flush around the entire perimeter.
8. 8

   Reconnect battery and test
   Reconnect the negative battery terminal. Turn the ignition to ON position without starting the engine. Test all sunroof switch functions including tilt up, slide open, slide close, and verify the one-touch auto function works in both directions.

2. Verify dome light operates correctly after reassembly
3. Perform window auto-up/down relearn procedure if equipped: fully lower each window, then fully raise and hold button for 2 seconds

Verification

• Test sunroof tilt function in both directions
• Test sunroof slide function in both open and close directions
• Verify one-touch auto-open and auto-close functions work properly
• Confirm sunroof stops at obstruction detection (auto-reverse safety feature)
• Check that dome light functions normally
• Inspect overhead console trim for proper fit with no gaps or loose clips
