2007 Itasca Meridian 39K Wipers not working

[Fireflies]

Greetings from across the Pond in the UK

Could anyone please help me get my wiindshield wipers to function. They stopped working on my trip to a camp ground and I'm struggling to isolate the problem

I've examined the fuses in the genny locker below the screen and behind the removable plate that accesses the relays...etc. All appear good but couldn't locate a dedicated fuse for the wipers.

Is it a relay thats blown, if so which one?

I've tested the actual combi wiper dash switch and there's no power to it with ignition on which I find strange

No obvious chafing or loose connections either. Also no power to the motor

I'm sure there's an easy solution to this but our time here on site is to assist our daughter in wedding preparations for her big day in two weeks so struggling to give in depth time to this issue

Everthing else works just fine

I'll try to attach a photo of the fuse bay for reference

Thanks in anticipation

Pete

Pete ; your power to the wiper switch , being an ignition powered circuit . is most likely one of the Freightliner " IGN " fuses so I'd say to have a voltmeter or 12 volt test light and check them all .

Many differences in wiring between any schematic info I have on 99 and 01 chassis , both those have two fuse/relay boxes where you only have the one.

Because Freightliner didn't supply a dedicated wiper fuse ( they don't supply the wiper system or the windshield ) in my case Newmar tapped into the IGN 1 circuit for power on my coach I'd imagine somewhere Winne has done the same .

Thanks for that info. The fuse marked 'Wiper' (opt) is missing so guess you're right to advise its wired in to something else
We checked each fuse visually and tested the long solid style ones and all are OK. All ignition cicuits appear fine and the RV runs fine which is confusing

I read on another thread that there may be a single yellow wire with an inline fuse somewhere that then runs in to a relay. I'm not too hot on electrics but will check for this tomorrow

Pete; in the " Sticky " posts at the top of the Winne forums list , go to " Winnebago , electrical diagrams ; and a link there will get you all Winnebagos wiring diagrams for your coach .

A quick look at 07 Itasca 39K front end 12 volt ,wiper wiring showed the motor/ washer reservoir and wires back to a Freightliner multiple connector , but not exactly where you can download the whole pdf .

I've looked at the PDF too and drew a blank but it definitely looks like a torch and mirror job to find it

Here's the Automotive Wiring Diagram for your coach which has wiper wiring diagrams on the last page. You may also want to refer to the Wiring Identification Guide and Wiring Diagram Help.

The Front End Wiring Installation diagram may also be helpful, as it details the breaker connections, etc.

I'd begin at the ignition switch, locate the wire going to the wiper switch and with ign on-not running, test that wire for power to a known good ground.

A huge thank you to you Guys for helping with this problem
The wiring diagrams were very helpful and I've downloaded them for future reference
After gaining access to the rear of the dash, the underside (a real pain) and testing every relay/fuse I could find I checked in the front panel again
There's an unmarked rogue relay there sitting on its own top left which I pulled, tested and found to be faulty
A simple substitution had my wipers/washer up and running again so now can have a far safer trip home
Pic is below for reference but many thanks to you all for your help

Just fyi, here are the full Wiring Diagrams for your coach (except, of course, for any mods made to adapt to your 240V UK world )

Many thanks

Fireflies, I can't help you with the wiper problem but I'm sure the other posters will be of great help, they usually are.

I am curious tho, what makes your Journey different with "UK spec"?

Hi Barry & Sue

Ours is an Itasca Meridian, a Journey in a different hat

'UK Spec' effectively means the internal electrics are 240v and the sockets are 3 pin UK type with earthing. There's a 110v/240v transformer/transfer box under the bed and some associated wiring

Roadwise the flashing red indicators have been swapped out for amber ones

The genny/convection oven/norcold fridge/AC are still 110v wired so presumably all that side remains US spec, only the domestic power points are changed

I had a nice 3kw Victron solar inverter/charger set up installed when I bought it 3 yrs ago with 900w up top to go long term off grid touring in Europe as we'd been doing the previous 6yrs in a 'conventional EU motorhome '
After 5 months success we suffered a bad motorcycle accident and spent the last 3 yrs in the RV doing extensive rehabilitation and physiotherapy
The RV has been brilliant for that and we intend to keep him as our UK base whilst touring soon again in a 6.36m panel van conversion coming soon

The RV is superb, yes its a little dated but runs beautifully with only 13k miles on the odometer and still delivers a 'second home' experience day after day

Regards
Pete
