I have a 2000 Rodeo LS. It did not have fog lights or even the fog light switch next to the steering column (I purchased the switch from Isuzu and have it installed.) Fortunately, the fog light wiring was already done on my car, which saved me quite a bit of work. The issue that I''m having is that I am getting power to the switch, but the fog lights aren''t working. I have tried both combinations for the wiring set up of thewires from the fog lights to thecontacts.I alsochecked the fuse in engine compartment box and it is not blown. Does anyone have any suggestions? Edited by: nyr27ak

 

are the fog light relays installed in the fuse box in the engine compartment

 

The Frog lights need the relay that is located in the fuse box under the hood and behind the battery. If the vehicle did not come with factory frog lights you must add the relay also to make the factory wiring work.
Good luck,
Dennis
