So, I have an 05 Titan and I'm having headlight issues. On low beam, the drivers side doesn't come on. On hi beam, both sides come on. I've checked the fuse in the IPDM and it looks good (for the driver side low beam). I haven't checked voltages on the bulb side because I don't have a multimeter. I was wondering if there was anything else I could check or even a wiring diagram that someone might have to help troubleshoot. Is it possible that the signal for each lamp splits right off the bat at the control on the steering column? If so, it could possibly mean that the switch is bad. Was thinking about doing some continuity checks on that too.


Any help would be greatly appreciated.

have you tryed to put the bulb from the left in to the right and the right in to the left to see if its a wiring problem or a bulb problem?

Yeah, ive swapped bulbs and bulbs are fine.

well my guess is the wire from the socket to the connection that links the 2 lights together whether it be back at the relay or or just a connector part way back in the wiring loom

There should be a detailed breakdown about the voltage path in the factory service manual for your truck... www.nissanservicemanual.com

Possibly a wiring diagram as well, although Nissan has gotten increasingly bad about not putting schematics in their electrical manuals for the last several years.

Good luck!
