Test 97B - Diagnosing Intermittent Wiper Problem
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For appropriate wiring diagram, see WIRING DIAGRAMS section at the end of this article. Perform TEST VER-1B after each repair.
CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.
- Turn ignition off. Gain access to Body Control Module (BCM). BCM is located behind left side knee panel. Disconnect BCM Blue connector. Turn ignition on. Go to next step.
- Using scan tool in voltmeter mode, check voltage on BCM Blue connector terminal No. 17 (Dark Green/Yellow wire). With probe connected, slide wiper switch to each intermittent mode. If voltage is present in each intermittent mode, replace BCM. If voltage is not present in each intermittent mode, go to next step.
- Turn ignition off. Disconnect multifunction switch connector. Using an external ohmmeter, check resistance of Dark Green/Yellow wire between BCM Blue connector terminal No. 17 and multifunction switch connector terminal No. 1. If resistance is less than 5 ohms, replace multifunction switch. If resistance is more than 5 ohms, repair open Dark Green/Yellow wire.
