Sunroof / Moonroof: Testing and Inspection
OPERATION CHECKCAUTION: Be careful not to damage the moonroof switch or the driver's dashboard lower cover when prying the switch out.
NOTE: Check the No.51 (20 A) fuse in the under-hood fuse/relay box and No.24 (7.5 A) fuse in the under-dash fuse/relay box, before testing.
1. Pry the switch out of the driver's dashboard lower cover.
2. Disconnect the 4P connector from the switch.
3. Connect the No.1 (YEL) terminal to body ground with a jumper wire, then turn the ignition switch ON (II). The moonroof should open.
- If the moonroof opens, check the switch.
- If the moonroof does not open, check for:
- an open in the YEL wire.
- faulty moonroof open relay.
- faulty moonroof close relay.
- poor ground (G401, G402).
- faulty open/close switch.
4. Connect the No.3 (YEL/RED) terminal to body ground with a jumper wire, then turn the ignition switch ON (II). The moonroof should close.
- If the moonroof closes, check the switch.
- If the moonroof does not close, check for:
- an open in the YEL/RED or GRN/RED wire.
- faulty moon roof close relay.
- faulty moonroof open relay.
- faulty tilt/close switch.
5. Connect the No.2 (BLU) terminal to body ground with a jumper wire, then turn the ignition switch ON (II). The moonroof should tilt up.
- If the moonroof tilts up, check the switch.
- If the moonroof does not tilt up, check for:
- an open in the BLU wire.
- faulty tilt/close switch.
6. Connect the No.3 (YEL/RED) terminal to body ground with a jumper wire, then turn the ignition switch ON (II). The moon roof should tilt down.
If the moonroof does not tilt down, the open/close relay must be faulty.
7. Check for continuity to body ground on the No.4 (BLK) terminal.
There should be continuity.
- If there is continuity, check the switch.
- If there is no continuity, check for:
- an open in the BLK wire.
- poor ground (G401, G402).
