I HAVE A 2001 YUKON XL WITH THE DENALI PACKAGE AND I AM HAVING ISSUES WITH MY COURTESY LAMPS. NONE OF MY INTERIOR LIGHTS EXCEPT FOR THE DASH WHICH WORKS FINE BY THE WAY WORK. OVER HEAD LIGHTS DONT. THE FUSE IN THE ENGINE COMPARTMENT IS A 15AMP AND IS CONSTANTLY BURNING. WE THINK IT IS A SHORT BUT WE DO NOT KNOW WHERE TO START LOOKING. EVERY TIME I PUT IN A NEW FUSE IT BURNS ON CONTACT. IS THERE SOME SPECIFIC PLACE I SHOULD LOOK OR IS IT GONNA BE A NEEDLE IN THE HAY STACK TO FIND A SHORT.

I have a 2001 as well and have the same problem. Have you found any resolutions to your problem. I agree with you i dont know where to start. I also have a sunroof that doesnt work. They all went out at the same time and the fuses keep blowing. Let me know if you have found the problem. thanks
