cruise control problem when towing
hi, We've got a 2005 tiffin on a workhorse chassis. The cruise control was disengaging when using signal lights. Thanks to the forum, I found the problem to be corroded sockets in brake, And tail...

TimfmCT,
Thanks for posting your solution. I missed your original post, but I had a problem with my Workhorse Chassis when towing. My magnetic add-on lights weren't working properly (the directionals weren't blinking as bright as they should, and the lights didn't look as bright as they should) and the cruise control on the motorhome didn't work when towing. It thought it was a bad ground/bulb/socket/etc. and checked all of those on the lights. All looked good.
I tracked it down to the Workhorse supplied 4-wire connector on the motorhome near the hitch. One of the wires at the connector had an open in it. Apparently, when the lights were connected, it set up some strange feed-back signal that messed up the cruise control. I'm guessing it thought the brakes were on. You wouldn't think an open would cause that type of problem, but it did. When the lights weren't connected, it worked fine. :h
Changed the connector, no problems since. Hopefully your problem is fixed. But if not, change out that 4-wire connector on the motorhome.
