Both Mirrors Inoperative
- Fuse Check Check RADIO (15-amp) fuse, located in fuse junction panel. If fuse is good, go to step 4). If fuse is blown, go to next step.
- System Check Replace blown fuse. Turn ignition on. Observe fuse. If fuse does not blow, go to step 4). If fuse blows, go to next step.
- Short To Ground Check Turn ignition off. Unplug 11-pin connector from interior fuse junction panel. Unplug mirror switch connector. Measure resistance between ground and Blue/Black wire. If resistance is less than 10,000 ohms, repair circuit. If resistance is greater than 10 k/ohms, replace shorted mirror switch.
- Power Supply To Mirror Switch Check Ensure ignition is off. Ensure mirror switch is disconnected. Turn ignition on. Measure voltage of Dark Blue/Black wire at mirror switch connector. If voltage is less than 10 volts, repair Dark Blue/Black wire between fuse junction panel and mirror switch connector. If voltage is 10 volts or greater, go to next step.
- Mirror Switch Ground Check Turn ignition off. Measure resistance between Black wire at mirror switch connector and ground. If resistance is less than 5 ohms, replace mirror switch. If resistance is 5 ohms or greater, repair open Black wire.
