I have a Ducato 244 Maxi van.
I had the cab valeted a while ago, and on my return to pick it up, it was like brand new.
Alas, soon the fuses for the brakes and the webasto heater began to blow, or the instruments all failed.
So I took the van van to a garage (I was hundreds of miles from home), and the guy there took a look.
He told me that the whole fuse boxes on both sides where covered in a thick layer of some kind to gunk.
I remember that this odd yellow gunk was found in tiny pools in the odd areas under the seats in the pockets in the door, and at the time guessed it was from the valeting people.
He removed the fuses and washed them in a degreaser, then sprayed a cleaner all over the fuse holding modules. (Battery was disconnected).
On the refit and restart of the ignition, everything was working...hurray.
Then he showed me via a torch, under the dash area...the gunk had run down the air intakes and gaps from the window screen and on its way down evaporated. He said to expect more trouble when the weather warmed up, as there are electrics under the dash near the top.
He suggested I leave the van a day with him but I was loaded up and a delivery was timed for a few hours later, so I paid and thanked him, and went on my way.
That warning now seems to have come true.
The indicator rely and the Window /Locking Module are playing up.
It is a similar effect as a loose connection, they work and then dont, random and sometime for a while or a few days. I checked all the fuses, connections but it did not help.
The right indicator rear stopped working, and to get it working was either run the hazard lights switch and leave on for a while, and then trying again, to find it works or the odd bang with a fist on the center of the upper dash. The windows and central locking are the same, work in hot weather but not in cold and to fix it is the same, a few bangs on the dash. I guess the gunk has got on the relays, thus causing a bad earth or simple oxidizing the metal.
Here is my problem. How do I get at the indicator and where is it plugged in, and the module, so that I can remove / clean / or renew? I removed the radio and the upper plate where the folding note holder is, only to find a metal plate/strut. The power cable loom could be mover a little but they vanished towards the front and out of sight and as always in a space where my paws cant reach. Wobbling the loom made the indicators work and not work. What do I need to remove to gain proper accesses?
I am sure the relay and module are dirty and the connections have been effected by the gunk, because before this cleaning stuff was sprayed all inside the cab, I never had this problem.
Any Advice would be appreciated, with a little detail on how to go about it.
Thanks in advance.
PS: Please save my sanity, this has had an adverse effect on my scalp where I have torn tufts out during a Indicator torment failure induced tantrum. Teddy has stopped talking to me.
