2015 Thor Vegas Wiper motor & washer fuse???

Hi all. The windshield wipers & windsheild washer stopped working. Where is/are the fuses? 😞

This is my first post. I would like to say thanks to everyone who does and this saved me a bundle.

I had the washer pump fall out of the tank. So yesterday when I had my 2015 Axis in for an oil change at a Ford dealer, I asked them if they could look at it. Won't go into the fiasco of the oil change but went to pick up the coach and now the windshield wipers do not work. It is 5:30 closing time and they are just finishing it up with no offer to do anything with the wipers. Its now my problem.
I drove it home since I am pretty good at working on the coach and figured I would work on it myself.
I looked for information here and RV.net forum. I had no power at the switch or motor. I located the resettable 20 amp fuse marked P6-1 F02 Wipers in the fuse panel described above. Placed a circuit breaker in place of the fuse and still no power. Put power to the the motor and it worked. Put power to the switch and it worked.
I finally found this on RV.net: "Fuse #45 on inside Fire wall fuse box at left of pedal. Wipers work fine until I try to use Window WASHER. That blows the 5 Amp. fuse. Apparently there is a problem with the washer motor".

Low and behold there is another fuse box inside the cabin to the left of the pedal. Now talk about easy access!!! Not!

Sure enough the #45 fuse is blown. Replaced it and the wipers work. Used the washer pump and it blew the fuse. Took the pump out and hot wired it and it is set up. Found a replacement pump at NAPA and everything is back to normal. I spent about 8 hours troubleshooting and getting this fixed. I am just glad I wasn't spend $87.50 and hour at the dealer. It should have been an hour if I had known there was another fuse box!

The odd thing here is at the moment is that there is no fuse in P6-1 F02 Wipers and they still work. Other diagrams I saw say this is a spare.

Anyway, I hope this helps other if they run into the same problem.

Often a fuse serves two components, especially one like a wiper pump that is rarely used and doesn't necessarily draw a lot of power. On my Monaco, they were pretty good about labeling everything in the main fuse bay, but over time I learned that there were a few fuses that did double duty. Your fuse can also be providing the trigger for a relay that is then powering your wipers, a large power draw item. Since the relay doesn't require a lot of amps, they can get away with a couple of items on the same fuse.

On my Diplomat, the power front visors (two of them) would blow the fuse if they were both used at the same time. It was a 5 amp that I eventually replaced with a 7.5 amp and solved the problem.

I'm sure there will be some naysayers, but I would bump that fuse to a 7.5 amp and see if you still have an issue. If you do, you might have a bad wiper motor or sprayer pump.

Still wonderin?

Just makes me WONDER WHY the washer & the wiper are on the SAME 5AMP fuse?

FOUND IT! Fuse #45 on inside Fire wall fuse box at left of pedal. Wipers work fine until I try to use Window WASHER. That blows the 5 Amp. fuse. Apparently there is a problem with the washer motor. I'll call Thor tomorrow. Thanks for all U'r help. LOL

I've checked the fuse #49 under the hood the book says for wiper motor, its ok. I've checked any fuse that could possibly be associated in the electric box in the outside compartment, Driver side. No luck. Checked fuses on inside fire wall, left of pedal, no help. I've disconnected the washer motor in case it is the prob. and loading a sensitive relay, no help.???
