Having an issue with the park circuit not working on my wipers. Also the delay does not function, and when using the "mist" function the wipers will not shut off unless I shut the truck off.

Any ideas?

 

I'm assuming that when you say your delay function is not working you mean that it continuely wipes. All of the problems that you describe are related to the park function. It has been my experience that the park circuit that is built into the wiper motor itself has failed when you have these problems.

 

In that case replacing the motor itself should fix the problem, correct?

 

Yes, replacing the wiper motor will fix the problem. There is a way to check with an ohmmeter to be sure this is your problem. If I had a print handy I could check that for you. I'll see if I can find one within the next few days.
