MOONROOF / FUNCTION TEST







1. Remove the dashboard lower cover, and if necessary, remove the knee bolster.







2. Carefully pry the switch out of the left side air vent panel, then disconnect the 4-P connector to remove the switch.
3. Check for continuity between the No. 2 terminal and body ground.

- an open in the BLK wire.
- poor ground (G201, G401).

* If there is continuity, go to step 4.

4. Check for voltage between the No. 4 terminal (+) and No. 2 terminal (-) with the ignition switch ON (II). There should be battery voltage.
* If there is no battery voltage, check for
- blown No. 1 (30 A) or No. 14 (20 A) fuse in the under-dash fuse/relay box.

5. Connect the No. 4 terminal to the No. 3 terminal, and the No. 1 terminal to the No. 2 terminal with jumper wires. The moonroof should open when the ignition switch is turned ON (II).
* If the moonroof opens, check the moonroof switch.
* If it doesn't open, remove the headliner and check the motor.
