Windshield Wiper Test 2C - Wipers Not Working At All
NOTE:
Perform WINDSHIELD WIPER TEST 2A
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 - VERIFICATION PROCEDURE
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Remove front wiper ON relay from Power Distribution Center (PDC). Ensure connector is clean and not damaged. See Figure in EXTERIOR LIGHT TEST 2A. Remove HI/LO wiper relay and ensure connector is clean and not damaged. Using scan tool in ohmmeter mode, measure resistance at terminal "D" on front wiper ON relay socket. If resistance is 5 ohms or greater, go to next step. If resistance is less than 5 ohms, replace PDC.
- Using scan tool in ohmmeter mode, measure resistance at terminal "B" on front wiper ON relay socket. If resistance is more than 5 ohms, go to next step. If resistance is less than 5 ohms, replace PDC.
- Disconnect wiper module connector. See Fig 1 . Using scan tool in ohmmeter mode, measure resistance at terminal "E" on wiper HI/LO relay socket. If resistance is 5 ohms or greater, go to next step. If resistance is less than 5 ohms, repair short to ground in Brown/White wire between terminal No. 1 on wiper module connector and terminal "E" on wiper HI/LO relay. Replace wiper fuse No. 19 (30-amp).
- Using scan tool in ohmmeter mode, check resistance at terminal "D" on wiper HI/LO relay. If resistance is less than 5 ohms, repair short to ground in Red/Yellow wire between terminal "C" on wiper HI/LO relay socket and terminal No. 5 on wiper module connector. Replace wiper fuse No. 19 (30-amp). If resistance is 5 ohms or greater, replace wiper motor and wiper fuse No. 19 (30-amp).
