Hi all.

I have a 2005 mk2 Focus 1.6 (115hp) Sport.

Every now and then the rear nearside indicator stops working and when this happens, it causes the side and front indicator to flash a lot faster than the norm!
After a while it goes back to normal!

Any ideas anyone?

Many thanks

Clarkie

p.s. The offside headlight bulb blew just before Christmas and now the nearside headlight bulb has blown! - Coincidence? Or part of the indicator problem?

 

head light bulbs can just blow any time they don't last for ever as for the indicator bulb
you may have a lose bulb holder which every now and then the bulb will come lose and that's what your problem is easy to fix just take out the bulb holder remove bulb and use a long nose pliers and gently pinch the bulb holder together the refit everything back job done

 

Nice one. Thanks minder

 

Same problem for me with a 2007 Focus LX - rear left indicator bulb not working on indicating or when centrally locking the car, front left blinking twice as fast. Checked fuse (7.5 amps, fuse number 53 according to this diagram: http://www.autogenius.info/ford-focu...e-box-diagram/), fuse fine. By swapping the bulb with the rear right, I proved it wasn't the bulb at fault (i.e. I got the same problem on the rear left with the bulbs swapped, the rear right worked fine). By swapping the bulb holder with the rear-right I proved it WAS the bulb holder at fault (i.e. now the rear-right didn't work and the front right blinked twice as fast). Took the bulb out of the bulb-holder, released the bulb holder from the rest of the assembly by pressing the black release clip and pulling, prised off the inner orange plastic holder inside the bulb holder by using a small-bladed flat head screwdriver to push the three holding clips in at the bottom, then made sure with the small-bladed flat head screwdriver that the contacts were a) pushed down into the holder; b) separated to avoid short circuits; c) springy enough to make contact with the bulb. Then carefully replaced the orange plastic holder, being sure to tuck the vertical electrical connection inside the prescribed place on the side of the orange plastic holder. Tested before re-fitting and it worked. Then re-fitted and re-tested and again it worked. So all I can conclude is there was a loose connection in the bulb holder or the mental connectors were touching in the bulb-holder. Anyway, saved myself a potentially expensive and time-consuming trip to the garage, so thanks for all the advice here that guided me to the solution.

 

We have 2 focus's in the family a mk1.5 and mk2. They have both suffered the same problem with brake lights failing to work properly and each time it was discovered to be the bulb holder.

Some moisture got in and corroded the terminals which is seen by a white residue powdery substance. It's easy to remove them for a quick check, hope this helps .

edit: good advise above from Tommy to swap the known good side bulb holder over to test. Should be an easy way to check.
