The intermittent features do not work and it acts like it has only two speeds. I have been through 3 of the modules from Pull-A-Part, and recently read on here where you can disconnect the harness and just plug the two ends together and test that way. I did that and it acts exactly the same so that eliminates the module being the problem. The questions is how do I test if its the switch or the motor?

Additional symptom is that it stops wherever the wiper blades are when you turn the switch off with or without the module/s in.

Thanks for any additional info, I've searched through the forum but didn't locate information on testing the switch vs motor (could have missed it though).

 

I took the motor apart and cleaned everything, and replaced the linkage joints while I as in there. Still doesn't work..
