Huge electrical problem, no turn signals, aircon, wipers...

Post by tonza » Mon Jan 28, 2019 3:49 pm

Hi,

I have a huge electrical problem with my 1989 Busso. Engine is working normally, also headlights work but NONE of the following works: Wipers, power windows, aircon (not even blower with econ mode), turn signals. I can't even here relays to click or anything while trying to use turn signals.

Could it be that these get their power from the same circuit or something?

Help needed! Thanks a lot!

I don't know if you have fixed it by now, but I think you have more than thing that has gone wrong, as my guess would be that more things would have stopped working otherwise. Did it all happen at the same time?

I think it would make sense to look at the backside of the fusebox, as maybe some of the plugs going into it have come loose.

If the fan blower is not turning at all, you could try and give it 12V directly to see, if the unit actually works.

Let us know what happens :)

Thanks!

I got it working pretty soon after posting this. I asked some help from a friend and started to look wiring diagrams. With those I narrowed the problem down to ignition key mechanism. That was it. It just didn't give the signal to turn those things on.
