What's up with the lights on my Focus?
None of my parking lights work are working 2006 Ford Focus 1.8 diesel, wondering if anyone else have encountered the same problem.
Our answer:
Hi Ryan,
Not sure if this is related, but that generation of Focus is known to suffer repeated headlight bulb failure because of supply voltage surge. It can be fixed by installing a resistor kit, so probably one best left to a good mechanic or auto electrician.
