06 3500 cummins
the wipers only move real slow when they are on high. Sometimes they even stop. I already replaced the motor assembly and the multi-switch. Im thinking the only thing left is the controller? I can only imagine how much thats gonna cost!
Any other ideas?
thanks

 

Mine did that a while back and it was the motor assembly that needed replacement... Has been fine since...

I'm having the same problem. I'm replacing the motor today. I'll let you know if it works.

 

So I just replaced the motor on my 06 2500 and the same problem happened. On high it was extremely slow then it stopped. Not sure what to do next. We definately need some expertise here.

 

figured it out finally. It is the wiper module that is under the dash. It can only be ordered from a dealer. It is about 300 dollars.

 

Somewhere online you can report these type of issues with our trucks. This helps to creat recalls. Make them pay. When I sent in my report of my turn signals blinking the wrong direction, they asked me if I too had any problems with my WIPERS. I said no, but somewhere on DTR is a thread on where and or what this site is and file a complaint.
