Windshield Wiper Test 5A - Intermittent Wipers Inoperative
NOTE:
Perform POWER WINDOW TEST 1A
before proceeding. For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAM and WIPER/WASHER SYSTEM
article. Perform TEST VER-1A
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting any module connector. Ensure all connectors are clean and tight.
- If wipers do not operate continuously in intermittent mode, go to WINDSHIELD WIPER TEST 5B . Using scan tool, access WIPER MONITOR screen. Monitor I/WIPE enable voltage level. Turn stalk switch from low to high intermittent position. If voltage is about 12 volts, replace Body Control Module (BCM). If voltage is not about 12 volts, go to next step.
- Disconnect 24-pin multifunction switch connector. Using an ohmmeter, measure resistance between terminal No. 1 (White wire) on BCM Black 24-pin connector and terminal No. 2 (White wire) on multifunction switch 24-pin connector. If resistance is less than 5 ohms, replace multifunction switch. If resistance is 5 ohms or more, repair open in White wire.
