As the title says, only one is working. Checked the bulb - its good, even swapped with the other side to make sure it wasn't the issue. Nope, works on the other side. I looked at the fuse, but there is only one Fog light fuse...not a L or R ... so not that... Anything else I should look for?
It is most likely a loose or failing plug on the socket. Failing that, it's either an open in the return wire on one socket (they have different ground connections), or there is an open in the +12V coming from junction block J7(A)-J8(B), which is buried somewhere deep under the dash on the driver side. Best is to use a voltmeter and see which is the case.
Thanks, I suspected I'd have to do as such. I picked a craftsman voltmeter up. Just need to learn how to use it...then I'll try to find the problem.
