System Test "B" Heated Outside Mirrors Do Not Defrost
WARNING: This page is about a different car, the 1997 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
- Inoperative Mirror Check - Remove inner door panel. Disconnect 7-terminal heated mirror connector. Check voltage between terminals No. 2 (Dark Green/Purple wire) and No. 1 (Black wire) at motor connector. Turn ignition and rear window defogger on. If voltage does not exist, go to next step. If voltage exists, reconnect heated mirror connector and retest system.
- Battery Voltage Check (Dark Green/Purple Wire) - Turn ignition and heated mirror switches on. Check voltage at terminal No. 2 (Dark Green/Purple wire). If voltage does not exist, go to next step. If voltage exists, repair open in Black wire between connector and ground.
- Short Circuit Check (Dark Green/Purple Wire) - Turn ignition off. Using an ohmmeter, check resistance between Dark Green/Purple wire at connector and ground. If resistance is greater than 10,000 ohms, go to next step. If resistance is less than 10,000 ohms, repair short to ground in Dark Green/Purple wire. Retest system.
- Open Circuit Check (Dark Green/Purple Wire) - Remove fuse No. 30 (10-amp). Connect a jumper wire Dark Green/Purple wire at connector and ground. Connect an ohmmeter between ground and output side of fuse cavity. If resistance is 5 ohms or less, replace damaged fuse and retest system. If resistance is greater than 5 ohms, repair open in Dark Green/purple wire between fuse panel and power mirror motor connector. Retest system.
