Windshield Wiper Test 2G - Wipers Not Working At All
NOTE:
Perform WINDSHIELD WIPER TEST 2F
before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION
. For wiring diagrams, refer to WIRING DIAGRAMS
. Perform, after each repair, TEST VER-1A - VERIFICATION PROCEDURE
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Remove HI/LO relay. Using an external ohmmeter, measure resistance between component terminals "C" and "E" on HI/LO wiper relay. See Figure of WINDSHIELD WIPER TEST 2A. If resistance is 65-90 ohms, go to next step. If resistance is not 65-90 ohms, replace HI/LO wiper relay and replace fuse No. 15.
- Using an external ohmmeter, measure resistance between component terminals "C" and "E" on intermittent wiper relay. See Figure of WINDSHIELD WIPER TEST 2A. If resistance is not 65-90 ohms, replace intermittent wiper relay and replace fuse No. 15. If resistance is 65-90 ohms, go to next step.
- Disconnect right multifunction switch 7-pin connector. See Figure in INSTRUMENT CLUSTER TEST 5G. Using external ohmmeter, measure resistance between ground and terminal No. 1 (Dark Blue wire) on right multifunction switch 7-pin connector. If resistance is 5 ohms or greater, replace multi-function switch and fuse No. 15. If resistance is less than 5 ohms, repair short to ground in Dark Blue wire between fuse No. 15 (10-amp) and terminal No. 1 on right multifunction switch 7-pin connector. Replace fuse No. 15.
