Hey guys. I am having trouble with the fog lights on my 2006 Ram 4.7l. I replaced both bulbs yesterday and the lights still wont work. All the wiring and harnesses seem fine and I traced the wiring as far back as I could. I couldn't find a fuse specifically designated for fog lights but I pulled each fuse and did not find anything blown. Any suggestions?

 

If you have a multimeter test the connector. Your owners manual will tell you which fuse powers your fog lights. It might be something as stupid as your switch being bad.

Remember that the factory fogs do not work when high beams are on.
Check the relay that powers the fogs. That could be bad,... should be labelled in the under hood fuse box.
