Yep, definitely weird. I'd get the alternator checked with load (that's what I'd suspect is your problem). Take it to your local autoparts store (Pep Boys, Autozone, etc), and they'll do a free check of your battery and alternator. They can add a load and see how they perform.

Wouldn't the load from the main and the rear heater fans be way more than that of a couple of dome lights, or the horn for that matter?
 
Also, still don't know what component could "reset" after everything goes dead - I understand fuses and fusable links, but I am unaware of anything that works like an automatically resetting breaker.
 
I will put getting the alternator checked out on the list of suspects, thanks!

Wild guess - the headlight switch itself. Or the wiring 'around' it (just before or after).
 
Something is shorted out in there. This overloads the headlight circuit and trips a circuit breaker.
 
Turning the ignition off and then back on resets the breaker and things work for a while.

Because you have a number of different devices that when turned on will kill your engine (yet not blowing a fuse) then it appears that your main power from the battery and alternator, aren't keeping the main buss voltage up at 13 volts. Start with the basics here, making sure your battery and alternator are up to snuff. The battery test will also check out your ground, as too much resitance in that path could cause weird symptoms as well.
 
Once you are sure that your main power is good (if that isn't your problem), then you can start to isolate further by checking the voltages when it fails. The good thing (now that you are home), is that it apparantely is very easy to recreate the problem by turning things on....so you'll have an easier time in troubleshooting.
 
Keep us posted, as to what you find.

Only head/dome lights comes on / All others out by dj69

My 98 Infiniti QX4 (Nissan Pathfinder) has given me problems that started three days ago. First, my left turn signal was stuck (left on) when the lights were on. Few other lights were also off. After a while, the lights including the signal light worked again. What a relief.. Then today, everything started out okay. About 10 minutes later, all of the inside dashboard lights, turn signal lights, all rear lights, and lights for radio and climate buttons went out. It's still out. Anyone with any crazy problems like mine? Thanks.

Hard to diagnose this, given not much information to go on.
 
When you say the left turn signal was "stuck (left on)".....do you mean that the turn signal level was turned on and it didn't reset to neutral when you turned the wheel back, or do you mean the lever reset to neutral postion and the left turn signal light kept flashing, or do you mean the lever reset to netural position and the left turn signal was ON, but not flashing?
 
And how does "Few other lights were also off" tie to the previous statement, because the previous statement was talking about lights being ON, not OFF. Confused by what you are trying to indicate.
 
On your last statement about "all" rear lights. Are you referring to just the lights that come on when you turn on your headlights, or are you also referring to your brake lights, your turn signal lights, and your reverse lights as well.

I'm having the same problem with my Subaru Outback. I switch the lights and still have the problem on the passenger side. I get a high beam but no low beam. Did you find a resolution?

The majority of the time the bulb is bad.
 
If you have a volt meter, you can verify that there is voltage at the socket. If you have voltage, bulb is bad. If you have no voltage, then a fuse or relay is bad.
 
If you don't have a volt meter, replace the bulb(easiest to do), or swap it with the other headlight bulb (doubles the work).

Oldsmobile Intrigue Electrical by angelvaugn
Feb 12, 2007 (3:34 pm)

I noticed that my 1998 Intrigue's fan for the heat stop blowing. Then I found that the power locks, emergency lights, brake lights, antilock brakes, light the shows what gear I am in, and a couple other items stopped working also. The fuses seem to be OK. These items do not have the same fuse in common. What could be the problem here. I heard talk that the computer could be the problem. Any help will be appreciated. Thanks in advance for your help.
