Ford Focus 2005 Intermittent Indicators

[Rigsbyg]

Greetings one and all,

After the dashboard started to flash much quicker than usual, I expected one of the indicator bulbs needed replacing (I looked, and the front passenger failed), but after ignoring it for a few days it returned normal.

Now, though, the same situation is happening on the driver’s side at the rear.

So, it’s obviously not a fuse and I can only guess it’s a short somewhere in the wiring. I did, though, read on another website that someone had an issue with the Body Control Module which was costing them £150 back in 2013.

I’d just like a few variables before I take it in to my local car electrical shop.

Thanks :-)

Use a 21 Watt test lamp to check the circuit when it fails, start by connecting the test lamp to the indicator wire at the rear lamps plug

Not a short. An open circuit will cause those symptoms, which is essentially what you get when a bulb fails. You probably have a poor contact somewhere, and the bulb holder itself would be my prime suspect. If you can get the problem to reproduce while you're stopped, just look round the car and see which lamp isn't flashing - that's the one that needs attention.
