- Connect the No. 1 and No. 8 terminals with a jumper wire and check for voltage between the No. 4 terminal of the mirror connector and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch ON (II).
- If there is no voltage or neither warms up, check for:
- an open in the BLK/YEL or ORN wire.
- blown No. 14 (10A) fuse in the under-dash fuse/relay box.
- poor ground (G501, G502).
- If only one fails to warm up, check its defogger.
- If both warm up, check the defogger switch.
Retractable Mirror
- Connect the No. 1 terminal to the No. 5 terminal with a jumper wire. The mirrors should retract/extend when the ignition switch is turned back and forth between ON (II) and OFF.
- Both mirrors do not work, go to step 4.
- If the mirrors neither retract nor extend, perform the input test for the retractable power mirror control unit.
- If one of the mirrors does not retract or extend, check the retractable mirror actuator.
