Windshield Washer Control Module: Testing and Inspection
Intermittent Wipe/Washer Module
The following tests are to be performed if a problem with wiper system is only evident in the DELAY mode. These tests involve disconnecting the
intermittent wiper module, which can be found on a bracket located on the left side kick panel.
Condition: Excessive delay (more than 30 seconds) or in- adequate variation in delay.
1. Minimum delay (delay control to extreme counterclockwise position before first detent) 1/2 to 2 seconds.
2. Maximum delay (delay control to extreme clockwise position before off detent) 10 to 30 seconds.
3. If there is excessive delay or no variations in delay, refer to Multi-Function Switch Diagnosis.
Condition: In DELAY mode wipers run continually when washers are operated, but do not provide an extra wipe when the washer control is released.
1. Replace the intermittent wiper module.
CAUTION: When replacing intermittent wiper module, be certain to use the correct replacement module. If an incorrect substitution is used, the
wiper delay will be incorrect.
Condition: Wipers start erratically during DELAY mode.
1. Verify that the ground connection at the instrument panel is making good connection (free from paint) and is tight.
2. Verify that the wiring ground connections are tight and have good contact.
3. Verify that the wiring ground connections for the intermittent wiper module and the wiper switch are tight.
4. If condition is not corrected, replace intermittent wiper module.
CAUTION: When replacing intermittent wiper module, be certain to use the correct replacement module. If an Incorrect substitution is used, the
wiper delay will be incorrect.
