Hi, I am new to the forum and seeking advice on my Fiat Ducato 2.8 JTD 2005 year. Everything was working fine until last week when in one go I lost the heater fan, reverse lights, windscreen wipers, windscreen washers and the cigarette lighter. All the fuses are fine.
Has any one else had similar problems? I am a mechanic but more on the engine side rather than auto electrical. Wondered if it could be a body controller.
Thanks, Rick.

Greetings:

I came across this thread following a search on Google.

We have a 2002 Hymer motorhome based on 2.8 JTD Ducato.

We have exactly the same problem – no wipers, no washers, no heater fan (not sure about the cigarette lighter or reversing lights as van currently with dealer).

All fuses have checked and are OK.

Don’t know if it’s relevant, but our motorhome was in the dealers having a repair made to the rear bumper – bumper and rear lights removed and refitted. Raining when leaving the dealership – no wipers!

Any help much appreciated.

(I have also posted over on the Ducato Forum in the hope of better exposure and response).

A follow up with a solution – hope that this helps anyone else with the same issue.

I posted my problem on one of the Motorhome Usenet groups (MH-List) and a member there directed me to a post on the motorhometoday.co.uk forum.

Here someone with the same problem has reported that a short circuit in his reversing lights had caused the F31 fuse to blow which in turn took out his wipers/washers/heater fan/cab aircon/cigarette lighter.

Why these should all be on the same circuit is beyond me – the F31 fuse is described as protecting the ‘Ignition commuter’ in my handbook.

This is exactly what has happened to me.

Sorted out the reversing light short (a bit of corrosion in the lamp cluster), replaced the F31 fuse and all is now OK.

Hope that this helps others with the same problem.

I have a 1995 Ducato Hobby and experienced a similar problem. Simply a live feed wire came adrift from under the fuse box.
