Windshield Wiper Test 2A - Identifying Windshield Wiper System Problems
WARNING: This page is about a different car, the 1998 Dodge Intrepid and 1998 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform WINDSHIELD WIPER TEST 1A
before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION
. For wiring diagrams, refer to WIRING DIAGRAMS
. Perform, after each repair, VERIFICATION TEST VER-1A - BODY VERIFICATION TEST
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Remove wiper ON/OFF relay from Power Distribution Center (PDC). See Fig 1 . PDC is located in engine compartment. Refer to Fig. Figure in INSTRUMENT CLUSTER TEST 4B. Turn ignition on. Using external voltmeter, measure voltage between ground and terminal "A" (Red wire) on wiper ON/OFF relay socket. If voltage is 10 volts or less, repair open Red wire. If voltage is greater than 10 volts, go to next step.
- Install wiper ON/OFF relay in PDC. Disconnect Body Control Module (BCM) Bone 12-pin connector C3. BCM is mounted to junction block located behind left end cap of instrument panel. See Figure in CHIME TEST 2A. Using external voltmeter, measure voltage bet ween ground and terminal No. 4 (Red/White wire) on Bone harness connector. If voltage is 8 volts or less, go to next step. If voltage is greater than 8 volts, replace BCM.
- Disconnect wiper ON/OFF relay. Connect jumper wire between ground and terminal "C" on wiper ON/OFF relay. Using external ohmmeter, measure resistance between ground and terminal No. 4 (Red/White wire) on BCM Bone 12-pin connector C3. If resistance is less than 5 ohms, replace wiper ON/OFF relay. If resistance is 5 ohms or greater, repair open Red/White wire.
