Rear Wiper Switch Open
NOTE:
After making any repairs, perform BODY VERIFICATION TEST
under VERIFICATION TESTS.
- Turn ignition on. Using scan tool, select BODY then BODY CONTROL MODULE and monitor R WIPER SWITCH SENSOR voltage. If voltage is greater than 4.5 volts, go to next step. If voltage is 4.5 volts or less, go to step 5 .
- Turn ignition off. Disconnect rear wiper switch connector. Rear wiper switch is part of instrument panel switch bank located in center of instrument panel. Connect a jumper wire between instrument panel switch bank connector terminals No. 9 (Brown/Dark Blue wire) and No. 11 (Violet/White wire). See Figure . Turn ignition on. Monitor R WIPER SWITCH SENSOR voltage on scan tool. If voltage is greater than 0.3 volt, go to next step. If voltage is 0.3 volt or less, replace instrument panel switch bank.
- Locate and disconnect Body Control Module (BCM) connector C5. See COMPONENT LOCATIONS . See Figure . Using DVOM, measure resistance between of Brown/Dark Green wire between BCM connector C5 terminal No. 28 and instrument panel switch bank connector terminal No. 9. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Brown/Dark Green wire.
- Using DVOM, measure resistance between of Violet/White wire between BCM connector C5 terminal No. 16 and instrument panel switch bank connector terminal No. 11. If resistance is 5 ohms or less, replace BCM. See BODY CONTROL MODULE under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair open in Violet/White wire.
- Turn ignition on. Using scan tool, erase Body Control Module (BCM) and Front Control Module (FCM) DTCs. Turn ignition off. Conditions necessary to set this DTC are not present at this time. Check for related Technical Service Bulletins (TSBs). Check for faulty circuits while wiggling connectors and harness. Check for intermittent poor connections or faulty circuits and repair as necessary.
