'05 Titan with both low beams out. Swapped the relay for fog and for the rear window defrost, which didn't change anything. Both fuses are good, lamps are good, and wires apear good.........Maby unrelated: trailer tow brakes/turn signals out but running lights work. No blown fuses, and relay looks good. No signal for either L or R side at the trucks plug........IPDM bad? PLease help, I have to take it in for recalls on tues. but I dont have money for dealer priced diagnostic right now.
