When activating the windshield wipers, the first 3 cycles, the wipers are on consistent speeds and it activates the washer fluid pump as well. Only the max speed cycle activates the wipers only. The washer fluid button is working properly and all the relays and the fuses are working. What could be the problem?
Thank you in advance!

Hi,

It could be your wiper motor logic module. I have a wiring diagram below for your wiper system. To be sure you will need to for 12v on washer motor circuit while the wipers are on high while it is washer is running, From the switch to the wiper motor, If it doesn't show 12v. Check the wire from the wiper motor to the relay in the junction box. Please let us know if this was helpful and what fixed the vehicle. If you need more information we we will get it for.

Thank you
Joe T.
