Why does my Chrysler minivan Wiper not work?
The wipers should now run at the “low” speed. Grounding the red/white wire trips the wiper ON relay located in the power distribution center (PDC). If they don’t operate at low speed, it’s time to check the fuses and wiring.
What causes the intermittent wiper to stop working?
If you make a change in the settings and the wipers don’t react, it’s most likely due to a malfunction in the intermittent wiper relay. This can lead to a potentially unsafe driving situation as sometimes we encounter weather conditions that require the use of the intermittent switch.
When do I Know my wiper relay is bad?
One of the quickest indicators that a problem exists with the intermittent wiper relay is when the wipers are not intermittent and only work at one speed. The relay switch sends an electrical signal to the module that controls the operation of the wiper motor and gears inside.
What should I do if my windshield wipers are not working?
An efficient ice scraper is also a good idea when your windshield is frozen. Be sure to clear your wipers of any accumulated snow or ice so that they can flex properly and make full contact with your windshield.
What should I do if my rear wiper is not working?

If there is no voltage, check the voltage supply to the dash switch and check the rear wiper fuse. Remove the wiper switch from the instrument panel.
How do you test a rear wiper relay?
Test for voltage to the switch. Move the switch through its functions and make sure there is voltage present at each plug location. Follow the manufacturer’s guidelines for switch removal and test procedure for each specific wire location and function. Test the rear wiper relay.
How are rear windshield wipers the same as front wipers?
