How hard is it to replace the arm?
I was driving through a rain storm when all of a sudden my wiper arm went 90 degrees to the left. The arm was protruding past the drivers side mirror. Once at the campground I tried tightening the nut on the wiper arm, that didn’t work. I took of the arm partially,it was still attached to the rv by a black wire, to see that there was a sleeve or collar that attaches to the pin of the arm. What is the wire? Does the wire just unplug to attach a new arm?
Any help would be appreciated.

That "wire" is the hose for the spray, might just pull off but they really get tough to remove if they've been on a while.

The "wire" is actually the windshield washer supply tube. It just unplugs.

The center hub of the wiper arm is made of a soft metal that the wiper motor splines cut into when a new arm is properly installed. Once that soft-metal center strips out, you need to replace the arm with a new one. Tightening the old arm is, at best, a very temporary fix. In a pinch, placing a few strips of aluminum foil over the wiper motor splines and re-installing the wiper arm MIGHT buy you a short respite to get where you can replace the damaged wiper arm.

Contact the Newmar Parts Department to order a new wiper arm.

Has your coach (whatever it is) ever had windshield work done? The wipers are designed to be pressed on "once". If they removed and reinstalled them, you are seeing the result. It's a well known issue - do a search. Replacement wipers are in the $150 range. I met a guy that kept getting a nuisance leak attended to and each time they removed his wiper arm - cha ching. Unfortunately I am currently getting my windshields replaced - oh boy...

No I never had any windshield work done. I’ll try the foil for a temporary fix and order a new wiper arm. Thanks for the help.

I know you own a Newmar, but my assumption is that the wipers are the same as my Entegra. I’ve uploaded the procedure used for attaching the wiper arm on an Entegra with the same soft metal that forms on the spindle. I had the same issue with my passenger wiper last year. We don’t drive in a lot of rain storms.

On my Anthem, the upper level part number for the wiper setup is on the wiper motor. May be the same on your Newmar. This has allowed me to identify and order parts from Diesel Equipment. If anything, this may help with your problem.

Take a look at the documents and I hope they help.....

Good Luck
