Hi having major problems with my rear lights, when I switch on the fog lights the right one is bright as it should be the left one dim and both reverse lights come on dimly also and it stops the left hand turn signal working. Then when in reverse the fog lamps come dimly and the right hand tail light goes out!!

I've cleaned and re-tightened ground point g24, tried a different rear electrical control module and also fitted a new battery but the fault remains.

Has anyone else managed to cure such a fault? Should I be thinking of replacing the luggage compartment fusebox?

 

It sounds like a blown fuse somewhere. I've had multiple brands of cars do similar things over a blown headlight or tail lamp fuse.

 

I've checked all the fuses in the boot, but I might check fuses elsewhere on the car to be sure

 

I had same issues ... replaced rear fuse panel $110 and all is good.

Thanks, this is what I'm hoping I've ordered a used one from eBay just waiting for it to show up now so fingers crossed!

 

Almost certainly the rear fuse box - I had exactly the same problem and that resolved it.

 

Just an update for the record fitted the replacement fuse box just now and it has cured the faults with my rear lights. There was no visible sign of damage or corrosion to the old one or the connectors so obviously a fault somewhere on the pcb. Overall though very happy as fixed for £30! Thanks for the advice guys.

 

This fault seems to be appearing quite a lot now - when it first appeared on my car I searched around for info and it wasn't common at all - everyone said it must be the earth points or battery. But since I fixed mine, at least 3 people have posted with the identical problem, and the fuse box has fixed it.
