Windshield Wiper Test 8A - Wipers Not Operating In Intermittent Speed Mode
NOTE:
Perform WINDSHIELD WIPER TEST 1A
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 - BODY VERIFICATION TEST
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition on. Move wiper switch through all intermittent wiper positions. If wipers do not function in each position, go to next step. If wipers function in some positions, replace multifunction switch.
- Using scan tool, select SENSORS. Monitor intermittent wiper voltage at each intermittent position. If voltage changes proportionally in each intermittent position, replace Body Control Module (BCM). BCM is mounted to junction block located behind left end cap of instrument panel. See Figure in CHIME TEST 2A. If voltage does not change proportionally in each intermittent position, replace multifunction switch.
