check the ignition timing
After being stumped for some time about why only LEFT headlight not be working on 2001 Nissan Pathfinder (already checked bulb, fuses & relay), I took the car to my mechanic for repair. The problem turned out to be a "dirty" Daytime Light Control Module (DLCM) which is required in Canada. Oddly in the Pathfinder, the left/Driver-side headlight only gets to Ground through the DLCM and when that is defective, the left haedlight ceases to work. The right/passenger-side headlight does not go through the DLCM and wasn't affected by the problem (this has to do with different parallel vs serial circuit design). It seems the DLCMs in some cars require some resoldering, though in my case, a simple "cleaning" and reseating solved the problem, so my excellent Japanese mechanic (Kunio in Ottawa) saved me $280 by not having to replace the DLCM. Hopefully this explanation will be of help to others who may experience a similar problem ... Joe.
I had the same problem on my '95. First check the fuses under the hood. Second, check the switch on the steering column (google "how to check pathfinder headlight switch). Third. Ensure the Black wire from the headlight bulb connector is a solid ground (mine wasn't...) and I had to cut the wire and make a new ground connection. Apparently the ground goes to the chassis, and in my case, that chassis point was rusty... good luck..
could be headlight fuse or headlight switch.
could be the the headlight switch, dimmer switch, headlight relay, or a problem with the wiring
Check the back of the headlight switch. They had a problem with the electrical plug to the switch melting down due to high resistance (poor connections).
There is a problem with the SRS. Take it to a dealer and have this checked into, ASAP.
HI, I have the same problem with my pathfinder 2002 LE since today!!!!!!! The fan always stay ON. Did you find the origin of your problem?
Run a ground wire to that headlight. If it gets brighter, there is a problem with the ground in the wiring harness.
You need to get your control arms/bushings replaced. It sways at speeds on or above 60mph. I just had it done to my 97 pathfinder. It is a problem that they have. boo :(
i have the same problem
Most headlight circuit breakers are located in the headlight switches. Headlights are on a circuit breaker automatic reset so headlights don't go out if there is a problem and will blink on and off to get you off the road safely until you can fix the problem. Look for a short in the wiring between the headlight switch and the headlights themselves.
that 4wd is engaged and working if it blinks there is a problem with the 4wd
