I've picked up my B350 campervan almost a week ago.

The first thing I noticed when I went to drive it was that the turn signals don't work. Checking further I found that the brake lights also don't work, further testing by my suspicious self found the horn and reversing lights don't work.

The latter two don't really bother me, but the risk of being pulled up for not having turn signals and brake lights is very real.

Fuses are all okay. I have a test light and can check circuits if I know what colour wires to look for... any help would be greatly appreciated. As I've driven about 1500 miles with it the way it is, my nerves are near breaking point from watching mirrors looking for unmarked cop cars.

 

Does the van have a rear trailer harness?? Those are notorious for going bad.

 

Trailer harnesses aplenty...

Found the horn problem, a wire off under the steering wheel pad.

I have confirmed that there is power up the white lead to the switches when the brakes are applied, will start work on the trailer hookups, I'll be back with results.

 

By disconnecting the wire from the brake light to the trailer brake controller we got brake lights.

But after taking away everything else of the trailer hookup stuff there was no change,

 

Have wiring diagrams for it? If not, check here.

 

Hmmm.... tried several times, it keeps asking me to click the 'continue' button, but when I do it just tells me to do it again...

 

Of interest, possibly important...


Under glovebox. Is one of these the blinker canister? Of note here is the item circled in blue, I had the ignition on while looking in here and this thing was heating up. Then I noticed that it had heated up enough at some time to melt plastic on the fitting attached.

And there's what appears to be a rheostat control there, and circled in yellow is a fitting with three wires to it which doesn't connect to anything.

 

Nice site! Very handy!

 

Why, then, can't I progress with it?

It just continually tells me to click on the 'continue' button, then nothing happens and it tells me to do it again.
