Check your ground wire for that particular headlamp.
Loose or corroded ground connection on the right headlight assembly.
Headlight fuses for a 2001 Nissan Pathfinder are located in the engine compartment on the passenger side right behind the battery. You should be able to see and take the cover off a rectangular plastic box about 2" by 5" long. The two 15A headlight fuses are marked. Joe.
If the bulb is not the issue, it could be a problem with the wiring connection to the right headlight, a faulty headlight socket, or a problem with the headlight control module. It's recommended to check these components or have a professional mechanic diagnose and repair the issue.
The fuse box is located below the dashboard to the left of the steering wheel. Right headlight (10A) position 1 upper right corner. Left headlight (10A) position 2 just below it.
Not certain about the 91, but in the 89 they're in the fusebox. Open the glove compartment and look on the right hand side. The fusebox cover labels the location of the fuses. There are separate fuses for the left and right headlights.
on my 93 civic, there are 5 separate fuses for headlights. left low beam, right low beam, left high beam, right high beam, and daytime runner
To dissconnect the alarm on my newley purshased 1996 geo tracker i took 2 fuses out behind the toggle switch under the dash.It didnt work right and the light always stayed on.
Many vehicles these days have seperate fuses for the left and right headlamps, so check the fuses next.
on my 2004 tracker this was caused by a bad relay on the right side inner fender under the hood
Are both low and high beams out?
Probably you have a burned fuse. There are separate fuses for left and right headlights, and whrn one gets blown, the headlight will be dim because it is grounding through the other headlight.
You change the bulb for the right headlight the exactly same way as you changed the left only opposite. If you are replacing one headlight, even if the other still works it is best to replace them in pairs, for lights can dim and if you have a bright bulb and a dim bulb you could be in danger of distracting other drivers and causing an accident.
