Front Wipers Not Working In High Speed Mode
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2000 Plymouth Voyager, 2000 Plymouth Grand Voyager, 2000 Dodge Grand Caravan, 2000 Dodge Caravan, and 2000 Chrysler Voyager. However, it is still accessible from the selected car via links, so may be relevant.
- Remove wiper high/low relay from Power Distribution Center (PDC). PDC is located in engine compartment, next to battery. See Figure . Turn ignition on. Turn wipers to LOW speed setting. Measure voltage between ground and terminal No. 85 at wiper high/low relay socket in PDC. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair or replace PDC.
- Connect a jumper wire between terminals No. 30 and 87 at wiper high/low relay socket in PDC. If wiper motor does not operate, go to next step. If wiper motor operates, go to step 6 .
- Disconnect jumper wire. Turn ignition off. Measure resistance between ground and terminal No. 85 at wiper high/low relay socket in PDC. Move wiper switch to HI position. If resistance is less than 5 ohms, replace wiper high/low relay. If resistance is 5 ohms or more, go to next step.
- Remove lower steering column cover. Disconnect multifunction switch. See Figure . Connect a jumper wire between ground and terminal No. 5 (White wire) at multifunction switch connector. See Figure . Measure resistance between ground and terminal No. 85 at wiper high/low relay socket in PDC. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in White wire between PDC and multifunction switch.
- Remove jumper wire. Measure resistance between ground and terminal No. 8 (Black wire) at multifunction switch connector. If resistance is 5 ohms or more, repair open in Black wire between ground and multifunction switch. Ground location is located behind left side of instrument panel. If resistance is less than 5 ohms, replace multifunction switch.
- Disconnect wiper module connector. See Figure . Inspect connector for damaged pins, corrosion and loose terminals. Repair connector as necessary. If connector is okay, connect a jumper wire between wiper terminals No. 30 and 87 at high/low relay socket in PDC. Measure voltage between ground and terminal No. 3 (Red/Yellow wire) at wiper module connector. If voltage is more than 10 volts, replace wiper motor. If voltage is 10 volts or less, repair open in Red/Yellow wire between high/low wiper relay and wiper motor module.
