- Turn ignition on. Move wiper switch through all 6 intermittent positions. If wipers were inoperative in all positions, go to next step. If wipers were only inoperative in some switch positions, replace multifunction switch.
- Using scan tool, select SENSORS and monitor intermittent wiper voltage at each position of wiper switch. If voltage changes each time a different position is chosen, replace Body Control Module (BCM). BCM is located with junction block under driver's side instrument panel. See Figure . If voltage does not change each time a different position is chosen, replace multifunction switch.
