Well...I'm here to report I got the wipers fixed. It took me awhile to find the problem(s), as I hate to take any of my vehicles to a shop for two reasons...I feel like I'm getting ripped off, and secondly and most importantly, I like to learn about the problem.
I actually found two problems...
First of all, I have always been convinced that the wipers have never worked since day one and the problem I found supports this. I say this because I had the coach for about 2-years and never drove it in the rain...the first time I did, the wipers wouldn't turn off.
After replacing the multi-function switch that didn't fix the problem, I decided to check the motor and ended taking it apart and discovered all this grease on the contacts. Why someone would put this much grease in the unit boggles my mind.
The other problem I found was that the wiper controller was flakey. I had bought one a while back ago and tried it, but that didn't solve the problem. So, I put the original back in. However, i also had discovered that not all the intermittent wiper settings worked....which again, I wasn't aware of as I never drove it in the rain and when I did, I didn't use the intermittent settings. So, after removing the original and putting in the one I had, the intermittent settings worked.
