the wiper does not work with a delay

Unread post by cross398 » Sun Jun 10, 2018 6:32 am

Hello!!!
Dodge Grand Caravan 2000 3.0L
the wiper does not work with a delay.

When turn on in the first position, the windscreen wiper works once. Then it starts working when turn on the fast position.
But it does not work with a pause.
Washer Switch replaced a new one.

before you get into diagnosing the wiper circuits and body control module, check you wiper relays. just switch them with another relay that is the same like the headlight relay. switch the headlight relay with one of the wiper relays and check to see if intermittent works. If it still doesn't work replace that wiper relay and put the headlight relay in place of the other wiper relay. If the intermittent works with a different relay in either position just get a new relay.

if the intermittent wipers don't work with a different relay in either relay position you are going to have to check if you are getting the correct signal to the BCM or if the bcm is sending the correct signal out to the wiper motor.
