After a year of getting my wipers to work by spinning the switch thru the interval setting to high, they finally quit. They would work for months at a time before acting up. Now I can only hear a click from the wiper control module which switched to the "high" setting. Washer works, no wipers.

My question is, is the problem the multifunction switch or the WCM? Hoping its the switch as WCM are almost impossible to find.

 

i had issue close to the same as yours mine only worked on hi and medium and in a heavy rain they quit working, i bought a new motor and put it in thinking that would help and still nothing, i am thinking of just wiring my motor to a switch with a inline fuse so i dont have to worry about the wcm
