Wiper On/Off Relay Control Circuit Shorted High
NOTE:
Perform WINDSHIELD WIPER TEST 1A before proceeding with this test. For connector terminal identification and wiring diagrams, see
BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST: VER-2A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Remove wiper ON/OFF relay from Power Distribution Center (PDC). See Figure. PDC is located in engine compartment. See Figure. Turn ignition on. Place wiper switch in LOW speed position. Using external voltmeter, measure voltage between ground and terminal "C" (Red/White wire) on ON/OFF relay socket. If voltage is one volt or less, replace wiper ON/OFF relay. If voltage is greater than one volt, go to next step.
- Disconnect Body Control Module (BCM) from junction block. BCM is mounted to junction block located behind left end cap of instrument panel. See Figure.
