Wipers Do Not Operate In Pulse
- Turn wiper switch to PULSE position. Turn wiper switch to maximum delay position. Disconnect wiper switch connector. Using a DVOM, measure resistance between Brown/White wire and Brown wire terminals of wiper switch connector. See Figure . If resistance is about 500 k/ohms, go to next step. If resistance is less than 30 ohms or more than one megohm, replace wiper switch.
- Measure resistance between Black wire and Light Blue/Black wire terminals of wiper switch connector. If resistance is more than 5 ohms, replace wiper switch. If resistance is less than 5 ohms, replace pulse wiper control module.
