Tailights on 74 GMC Sprint

Have no tail lights on Sprint. Stop lights work, blinkers work, checked for grounds, all seem well. Could it be the head light switch? Fuse was changed out, 20a. Have not taken tail light bulbs out. ?

Take the bulbs out and check them. Did this just happen or did you just buy the Yukon?

It could be the bulbs. Does the car have a hookup for a trailer hitch? If so, check the wires there as they may have been broken or ripped off. Are the parking lights in the front working? You can check out the headlight switch as well. Check all the fuses to see if there is a blown fuse somewhere as well.

There is a plug-in wiring junction right in the middle of the truck behind the bumper. This is where you plug in a Hoppy or Draw-Tite adapter for trailer lights, and its a good place to do troubleshooting.

You can unplug the light harness at that junction and use a voltmeter to make sure you are getting power coming from the front of the truck to the lights. If you do get power at that point, then its somewhere in the wire running to the tail-lights, grounds at the light housings, or you have bad bulbs. If there is no power there, you have a fuse or headlight switch problem, or broken wires under the truck.

Bruce,
Are you certain that the ElCamino/Sprints of that era use the same type of harness that the c/k series use?

I believe it is more Chevelle and would use the same harness as a wagon----as both of my elkies do.

And this particular circuit can be checked under the dash----be looking for 6-7 wire connector close to the carpet near the fusebox.

Pretty sure all of that wiring runs thru the QTR panel on the Driver side
and crosses over behind the rear bumper.

You're right, I was getting my models confused. I read the name Sprint and somehow "remembered" it as one of the GMC truck models, not the El Camino derivative. I assume that its wired like the cars.
