Wipers Operate At Lo Speed; Switch In HI Position
- Turn ignition on. Connect a DVOM between Blue/Orange wire at wiper motor connector and ground. Set wiper/washer switch to HI position. Measure voltage. If voltage is less than 10 volts, go to next step. If voltage is greater than 10 volts, replace wiper motor.
- Turn ignition to lock. Unplug combination switch connector C1. See Figure . Using a DVOM, check resistance between combination switch terminals No. 18 (Blue/White wire) and No. 13 (Blue/Orange wire). If resistance is greater than 5.0 ohms, replace combination switch. If resistance is less than 5.0 ohms, check for open in Blue/Orange wire between combination switch and wiper motor. Repair wire as necessary. If wire is okay, replace wiper motor. If resistance is more than 5.0 ohms, replace combination switch.
