weird electrical fault

[Nij]

Took camper for MOT today, when the side lights (dipped or main too) are on, and the left indicator is on or four ways are on, the left hand side stays static on.
This only happened when it went in for the test (was fine this morning), left it ten mins and it went back to normal, nothing altered or adjusted, it fixed itself....any ideas?

not a clue but if you do find it let us no!

could be water ingress in lights or bad earth somewhere or wrong bulb fitted in brake lights

All bulbs are the correct ones, no water ingress anywhere. I suspected a bad earth, but its bloody intermittent so cannot guarantee that what ever I alter had fixed it...

Cheers guys

I had a similar problem with the glow plug fuse shorting out but that wouldn't be the case on a petrol.

on earlier vans the fault is commonly caused by corroded connections at the rear of the fuse box mostly due to water leaking down from the window screen seal. There is a flat 3 pin connector in the indecator circuit that often is right inline with the dampness at the behind top left of the fuse box .

same symptoms also caused by dashlight errors and the dim/bright control on the headlight switch
