Hi there, bit of a nightmare day here in the UK with my lovely USA Expedition.
The rear passenger side indicator went, which was quickly pointed out to me by drivers behind me, when I seemed not to indicate when crossing the oncoming traffic to turn right!

So I got a new bulb and replaced it. No change! The bulb was fine.

All the other indicator bulbs flash fine but I'm getting that double speed clicking when indicating right, that normally tells you a bulb is gone.

My local garage tested the bulb (fine), fuse (fine), the unit holding the bulb (fine and it flashes when local power is supplied) so it looks like the unit is not getting power.

We are therefore looking for any top tips if there is any known bugs or obvious things we have not already checked, then the local garage are after a wiring diagram to do some testing.

Anyone know where I can find a wiring diagram? The other issue is the car is not recognised on most systems for reasons we've covered before but it's a 2015 Expedition XLT 5.4L V8 (most 3.5L expy things have wroked so far though)
thanks
Mike

See if it's flashing normally at the trailer plug as well. I've attached that exterior lighting wiring diagram just in case. The actual flash control is done at the turn signal switch there on the steering column.

Funny conclusion to this - a specialist US Car firm that has a bunch of rich celeb clients told me they'd need it for ages and charge me a lot to diagnose and fix this.
My local back street garage said they bet they knew what it was, opened the little hatch in the panel in the trunk, pulled out some wiring and a connector, wiggled it and said "told you"! Loose connection. Fixed, no charge! Haha! Excellent!
