Question about 1991 Nissan Pathfinder
Turn the headlight switch== sometimes headlights go on, MOST of the time they DO NOT. Switch looks OK upon visual inspection. Wires are kinda small, is there a RELAY betwen switch and light?? I tried to "jump" the contacts in switch just to get home. "jumper" got REAL HOT, started to smoke! Waited for daylight....drove home. All other lights, signal, marker, brake, ect. work....ONLY PROBLEM IS WITH HEADLIGHTS. REGULAR AND BRIGHTS.
Your year Pathfinder, as mine, had a slew of bad head light switches. The headlight switches caused a slurry of intermediate nightmares for a lot of customers. Many complaints included:
1. My head lights sometimes turn off upon switching from low to high beams.
2. My lights turn completely off when I switch to high beams.
3. My lights flicker when I switch from high to low beams and vise verse.
4. My lights sometime wont turn on at all.
5. My lights go on and off on bumpy roads.
6. My lights sometimes come on by themselves.
All of these different but similar complaints contribute to the infamous head light switch. There has even been reports of continuous dead battery's due to the head light switch turning the lights on and off intermittently and eventually deadening the battery.
The light switch is relatively easy to replace. Simply remove the the two upper and lower steering column covers, disconnect the two wiring harness bulk head connectors, a couple screws and wallah.
Remember your safety and always dissconncet your your battey upon electrical repairs.
Just last week I bought a new head light switch for about $70.00. I would highly recommend buying a new head headlight switch and not buying a junkyard special. You will likely be buying another faulty switch.

There will be a relay. The headlight bulbs run off of a certain amount of amps and those amps are high enough to cause a fire. So that means a low amp switch is in the cabin of the vehicle and the power is under the hood. The relay is 98% of the time either good or bad, they usually don't flicker unless; they wires are lose at the relay or there is corrosion present.
Glad you waited till daylight! The reason the "jumper" got hot is because the amount of amps the headlights draw is more than the wires are safely able to handle. That is the reason for different gage wires and different metals in wires. This definitely proves your theory of a relay. It is safer to have those amps under the hood rather than in your lap. Glad you did not have a fire!
The relay and fuse for your headlamps are in a black plastic fuse box under the hood. Most likely that is where the problem is. It might not be the fuse or the relay just loose wires or corrosion. Keep in mind age of vehicle and location-Salt from ocean or northern streets.
Hope this helps and you learned something in the process.
