SOURCE: 2003 GMC Envoy Low beam headlights will not work.

I would start by checking the headlight relay and headlight fuse.  You also may wanna check to make sure the bulbs aren't blown out.  If those parts check out to be fine and in working order, you may need to replace the turn signal assembly in the steering column.  This part controls the hi/low beams.  This may sound crazy but, when GM wired their older trucks, they wired the headlights to go from the battery, to the hi/low beam switch, then to the headlight switch (to the left of the steering wheel) then out to the light bulbs.  You can kind of test to see if this part is good by making a fist and (with your headlights on) gently hitting the plastic cover for your steering column that is right behind your actual steering wheel.  This could cause your headlights to flicker on and off.  It's not 100% guarenteed that this method will work, but it may.  
Any questions, just ask!

SOURCE: online 1996 gmc yukon headlight schematic? free?

It sounds like it's your Headlight switch has gone bad, I'm thinking that the high beams are the daytime running light which is the same as your High beams. 
If you go to Auto Zone or Parts Source, they have the replacement switch with step by step instructions. Try not to run your Headlights too long from your running light's. The headlight's draw more amps then the running lights and can melt the wire which can result in a short and worst a fire.
If you remove the headlight switch from the dash, check the orange wire for power, if there is 12 volts. Good chance's are that the switch is bad, common on the GM's.
Good luck and hope this helps. I believe they go around $70.00 or do what most guys do. Salvage Yard range from $10.00 to $40.00 and there also have warranty.

SOURCE: The Heater fan in my 2003 GMC Yukon XL will not turn off

I don't know if you already fixed it, but I had the same problem on my 03 yukon, TysonRicky is right. In my case it was the blower control module. You can find it right under the glovebox. It cost me close to $100 for a new one, but very easy to replace. Can't even imagine how much it would've cost me if I had a mechanic do it.

SOURCE: 2003 GMC Yukon - fuel pump

Check your ECM fuse. There should be 2 fuses for your ECM. It's the ECM that controls the function of the fuel pump. Good luck friend and it's also common for the wire harness from the frame to the fuel pump to go bad due to corrosion from the bad weather we get in the winter and rainy spring and fall.

2003 yukon XL one headlight is not getting power, how do i troubleshoot?


If low and high beam both are failing to work check the ground for that side . If high or low one works and the other does not check the fuse for that beam as it has 4 fuses one for each side and low and high. The fuses are in the underhood fuse block . Marked as LO HDLP LT, HI HDLP LT, LO HDLP RT and HI HDLP RT . They are 10 amp fuses .

Headlights and dash lighting stay on when car is


Possibly your lights are on timer, or an auto dim, or auto lamp function.

Needs a jump every day


It sounds like the battery has a dead cell in it. Replace the battery. If you have an alarm installed remove the in line fuse from the alarm and see if that stops the battery drain.

Possible high resistance or poor connection on battery cables at battery, starter or engine block ground. Possible corroded cables (green flaky stuff under wire insulation causing high resistance and no start condition without high amperage.

High Beam Indicator blinking


My lights have had this problem for months. From time to time I try to fix it, but I have learned the following:

1. [EASY SOLUTION] After turning off the car and turning off the headlights, when I pull the headlight switch back (toward me) and then let go, the running lights turn off. [/EASY]

Extra information that I haven't figured out how to use yet:

2. Apparently the DRL bulbs operate through the high-beam bulbs; this is why you get the high-beam light when the DRLs are broken (or whatever) and why you can turn them off with the high-beam switch.

3. My wife took the car out for a fluid change once and said the mechanic pointed at a light on the car and said, "that bulb's out," and that if she fixed it the DRL's would work normally, but she forgot which light it was. He even told her what bulb it needed. I took it to the same place and no one knew what I was talking about.

I don't think about trying to fix this very often since I realized I could turn the lights off with the high-beam switch. I used to worry that that blinker was somehow draining the battery, but it never has (whereas I once drained a brand new battery just by leaving the interior light on all night). I hope I've helped!
