Hi guys really after some help, this morning was meant to be going japfest but noticed no rear lights when started car, got misses to double check and when brake and turn lights on nothing is working, still have rear indicators which is one thing, i also have no front side lights, when mocked up side lights they were working fine. But now they also not working.. wondering are the sidelights on same circuit as rear & brakes light?

I have also checked fuses in kick panel but couldn't find damaged fuse, am going to push car out and double check soon, i have also tried 3 rear brake light modules as have spares and still no joy, so guessing its nothing to do with lamp module.

Any ideas would be really apricated as not sure where to look or check next

If it helps i am running facelift headlights and indicators, all other lights work on dash

Just from a logic point of view, but as you've got the rear brakes and turn signals then it might be the stalk/switch, ie turn to lights and no feed to either front or back?

I'm not great with electrics but years ago i did have one with a turn signal problem and so replaced the whole stalks piece, and there is a connector on the column somewhere. if you found the right pins outs on that you could try feeding 12v and see if the lights worked, prove/eliminate the switch being the problem?

Well managed to fix issue, turns out the tail light fuse had blown and also the tailgate relay had gone, good thing i carry lots of spares in garage so didn't have to order and wait for parts, so pleased was able to sort it, just gutted missed japfest today

To revive this thread, this was the relay above the fuses in the kick panel that needed replacing ?

From memory I believe it was the fuse box under kick panel, also had to replace the relay unit behind plastic trim in passenger side of boot, think that failed and caused fuse to blow
