Both Mirrors Inoperative
- Check fuse No. 17 (7.5-amp) on Civic GX models, and fuse No. 16 (7.5-amp) on all other models. Replace as required. Remove power mirror switch. Disconnect switch from harness. See POWER MIRROR SWITCH under REMOVAL & INSTALLATION.
- Turn ignition on. Using a voltmeter, check for voltage between terminal No. 2 (Black/Yellow wire) and ground. See Figure or Figure . If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit in Black/Yellow wire between mirror switch and fuse box.
- Using an ohmmeter, check for continuity between terminal No. 4 (Black wire) and ground. If continuity does not exist, repair open circuit in Black wire or poor ground connection. If wiring is okay, substitute a known-good switch and retest.
