Windshield Wiper Test 2B - 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, TEST VER-1A - VERIFICATION PROCEDURE  .
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Stop low speed wiper motor actuation. Using scan tool, read intermittent wipe sensor voltage. Observe scan tool and move wiper switch from OFF position to HI position. If scan tool displays INTRMT WIPE: 0V, go to next step. If scan tool displays INTRMT WIPE:, with voltage present, replace BCM.
  2. Disconnect right multifunction switch 7-pin connector. See Figure in INSTRUMENT CLUSTER TEST 5G. Ensure connector is clean and not damaged. Using external voltmeter, measure voltage between ground and terminal No. 1 (Dark Blue wire) on right multifunction switch 7-pin connector. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Dark Blue wire between multifunction switch and fuse No. 15.
  3. Disconnect instrument panel 22-pin connector at Body Control Module (BCM). See Figure in CHIME TEST 3A. Ensure connector is clean and not damaged. Using external ohmmeter, measure resistance between ground and terminal No. 1 (Dark Green/Yellow wire) on instrument panel 22-pin connector. If resistance is 5 ohms or greater, go to next step. If resistance is less than 5 ohms, repair short to ground in Dark Green/Yellow wire.
  4. Using an external ohmmeter, measure resistance between terminal No. 2 (Dark Green/Yellow wire) on right multifunction switch 7-pin connector and terminal No. 1 on instrument panel 22-pin connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open in Dark Green/Yellow wire between multifunction switch and BCM.
  5. Reconnect right multifunction switch 7-pin connector. Turn wiper switch to LO or HI position. Using external voltmeter, measure voltage between ground and terminal No. 1 (Dark Green/Yellow wire) on instrument panel 22-pin connector. If voltage is more than 10 volts, replace BCM. If voltage is 10 volts or less, replace multifunction switch.
