There we were, headed for the Grand Canyon's North Rim on 15 May, opening day, elevation 8800 feet, and it started snowing
. About 12 miles from the park entrance to the campground, the windshield wipers STOPPED
, right in mid-stroke, leaving lots of snow on the windshield, and me unable to make out much beyond the edge of the road. And, the road is very twisty, winding, and tough to travel on a good day. With a little divine providence and cautiously slow driving, we were able to make it to the campground and find our site. NOT fun. The snow was intense and heavy, causing the wiper's thermal circuit breaker to overheat and stop the wipers from moving.
Once parked, my wife and I were able to hear a faint "clicking" coming from the bottom left of the driver's side foot well. I removed the panel, and looked for the offending culprit. Turns out there is a molex connector for the wipers at the extreme left/bottom of the front of the coach that controls the thermal overload relay and connection to the wiper motor. I could feel it clicking, leading me to be pretty certain that if I unplugged the connector, it would stop, and eventually reset. Turned out to be the correct guess. If you squeeze on both sides, it will release and you can pull it out of the connection panel.
After letting it cool for 10 minutes, I plugged it back in, and the wipers sprang to life, returning to the "set" position. I'm not impressed with this situation. When pushing 30K plus pounds and a toad down the road, it would certainly be nice to be able to see where you're going, even in a snow storm.
Thought I'd mention this, in case others encounter a similar situation.
