I have a Winnebago Sightseer 26P Model Year 2007. Last October I experienced a problem with the wipers going the minute I started the RV. I could not control the speed of the wipers or turn them off while the engine was running. After taking it in to a Workhorse Service Center it was determined) that a new wiper module was needed. This wipers worked fine in our travels to winter in Texas (granted we only had to use them a few hours on the way down). The next time we hit rain, less than a month after the initial repair, I started the RV and once again the wipers would not respond to the wiper control. I took the RV into another Workhorse Service Center and they fixed the problem?????? Well the wipers worked fine for the only day it rained. Started the RV the other day and you guessed it the wipers started working all by themselves. I finally just unplugged the pigtail connection so the wipers don't go when I start the RV but I don't have any wipers.
I am wondering if anyone else has experience this problem and what their solution was.
I am told (by technicians at two separate service centers) that this is a problem GM has had for awhile.

James,

On another forum there was a discussion about this problem on the Workhorse chassis. I wouldn't say it was a GM problem but I would say it is a Chevrolet problem. I have a 98 Yukon and an 04 Yukon and haven't had any problems with the wipers.

I did have the same problem with the wipers on my 88 Silverado and on my 06 Allegro Open Road on a Workhorse chassis. After taking them in to the dealer and having the same results you seem to be having I made my own modification.

I pulled the fuse under the dash and replaced it with with 2 wires with plugs plugged into where the fuse normally plugged in. Make sure the wires do not and can not make contact with each other. I then put an inline fuse in one of the wires and hooked them to an on/off switch which I mounted on the dash. This way when the wipers won't turn off I can flip the switch without having to get out and disconnect the plug. I can still use the normal switch to control them and the washer.

Good Luck,
Jon

Check the ground. several years ago we had a problem like this and it seems like the fiberglass front provides no ground, so a seperate ground wire must be run to the wiper motor. If the ground wire loses contact the wipers won't shut off.
