Question about 1992 GMC Sierra K1500

Open Question

1992 GMC Sierra headlights turn on slowly, after several attempts turning on/off

Don't know if some type of relay switch is going bad, turning on headlights, parking lights go on, but headlights are delayed a few seconds, sometimes not even going on. I then turn the headlight switch on/off several times before they go on.

My best guess is a bad ground common to both headlights.

I think the 50 amp fuse is for your starting circuit, not the headlamps, which is a 15 or 20 amp fuse. Did you try both dim and bright settings?

Since you don't know which fuse is for what, just remove and replace each fuse one at a time. As you go, visually inspect each fuse and test for continuity with an ohmmeter, then use a pink pearl eraser to clean the wafer tips before replacing. Do this methodically one at a time and replace any bad fuses with THE EXACT SAME AMPERAGE RATING.
Now, if your fuses are clearly marked and you do have a 50amp fuse in your headlamp circuit then you need to put the correct amperage in ASAP. If you have a 50 amp in the headlight circuit the whole circuit could be fried before the fuse blows, which is why you NEVER replace a fuse with a higher rated amperage.

Once you've worked over the fuseblocks go to the headlamp circuit and follow the wires and plugs coming from the lamps and going to the fuse block. Look for ground connections and tighten those, especially those coming from the headlamp wiring harnesses. If your lamps are good, the fuses are good, the plug connections are clean and making good contact and your grounds are good then all thats left is your headlamp switch and wiring to and fro. If you don't know what the plugs are for no harm can come from cleaning and reconnecting them, so you can't go wrong if you just do one at a time in a methodical fashion.
I have an old S-10 and the headlamp switch is junk- I have to hit it with contact cleaner every once in a while because Houston air quality is poor and there is a lot of ozone- all this corrodes connections- fuse maintenance cures a lot of ills.
After the fuseblocks I'd start by checking the actual headlamps to make sure they are working (check each filament for continuity or put 12v to it to test) and clean the contacts.

Then you can work your way back to the fuseblock and switch checking your plugs and connections. Its all pretty straightforward, just be methodical and clean your plug connections as you go. No schematic needed- just a little patience.

One thing to think about if your headlamps are both blown is that your alternator may be overcharging, or the regulator isn't working properly and your headlamps are blown because they got hit with too high a voltage. Eventually this will sulfate the battery and cause an internal short- if it is bulging you can be sure this is happening. So get your alternator and regulator circuit checked if this is the case.
Good luck, If this fixed ya then please rate this solution

You have a short to ground somewhere in the drl-fog lamp circuit. Check for obvious wiring connector or wiring to drl & fog lamps. check wiring for pinched or broken wires coming from sockets. If you don't find problem, you can trace wiring from lamps to main harnesses and hopefully find source of short.
hope this helps.

Suspect 7 pin connector problem , you should have power on the 8pm positioned and the centre pin position as you look into the socket (on vehicle. These pins are both male pins as you look at them . If ok check trailer wiring where it splits for either lamp assy ! Good luck

Cant say for sure, but you may be laying something on the sensor that turns the lights on, and causing car to think its night time, and turning on lights. The sensor that controls this is on dash ,drivers side near windsheild.

OK, This may not be a 92 gmc solution but I hope it helps. I had this problem on a non-gmc. The Hi-Lo switch on the sterring column grounds a relay to activate it and cause the switch to hi-beam. With Hi-beams on the steering column switch would loose the ground while turning the sterring wheel. The lights would shift to low-beam and back to hi-beam several times BUT looks as is they were going on and off. I run a new wire from the top of the steering column to a new ground to provide a ground path. The problem was cured.
