Front indicator wiring

[FC_Touring]

A month or so back i hit the front end of my car in the centre of the front, such that the sides of the bumper popped out of their clips and forward by about a foot.

Everything is now back together, but the front indicators don't work. The other indicators still work, there are no fuses blown, and its not the bulbs as I've tried new ones in there.

My guess is that when the sides of the bumper popped forward, they put strain on the wiring where it goes into the connector, so the wiring is no longer located properly in the connector (the bit that plugs into the back of the light unit).

There's no visual damage to the wiring or connector though. Is there a way of finding out at what point in the wiring loom the problem is occurring, without pulling the loom apart?

Any other ideas as to what the problem might be?

Anyone?

Did you put a new bumper on or the orginal?

I fitted a different bumper, but they weren't working on the original one after the crash either

Has a wire been cut in the crash?

My front indicators aren't working either, even though hazard, rear's and sides are.
