XF EDDIE 246 Posted June 1 I'm working on a 07 fairmont for a friend that has no tail or dash lights even though all the fuses are ok and it has no relevant dtc's. I haven't gotten a good chance to look at it and inspect the harnesses but I'm hoping someone here has some pointers as to what it could be. Right now Im suspecting a break in the harness for the tail lights but I really have no clue to whats wrong. Thanks in advance for any help you can offer, I only get at this thing half an hour at a time so any and all help is welcome! Share this post Link to post Share on other sites
Rod Racer 456 Posted June 1 The headlight switch might be the culprit for the dash lights. If can find a good one to try, that might narrow down the issue. If the car has a towbar, check the connections where the trailer plug wiring taps into the factory harness. If they used scotch locks, it may have severed the tail light section due to age or vibration. 1 XF EDDIE reacted to this Share this post Link to post Share on other sites
Rod Racer 456 Posted June 1 Not 100% sure, but check the fuse box carefully, sometimes the dash light fuse isn't the same as the tail light one. Share this post Link to post Share on other sites

I'd suss the binnacle switch, and/or relay Remove the relay and jump the load side relay contacts, using low amp test light (in case of wiring short) Share this post Link to post Share on other sites
