Please Help! Interior Lights Dont Work

[jrsstoy]

So my interior lights (dome, door,map, under hood ligths) dont work I found that my sunroof is no longer working either. Checked the fuses in the engine compartment and the courtesy lights fuse was blown, I replaced it and it blew instanly. I have tore my Yukon apart and have not made any proggress. Any ideas, anybody experience this problem

short somewhere, now, isolating it is another story, sorry to hear that man. Wiring gremlins are a bear to find.

First time I deal with something like this, Frustraiting that little fuse controls so much so isolating will be difficult but no other way around it. Thanks

it sucks cause it could be so many different things, but do try this being as your courtsy fuse was blown go to each light in side ur truck and check the bulbs. make sure the bulb has not melted together making a short even check your puddle lights to. not saying thats ur prob but its worth a try. but hopefully your sunroof was left in the closed position. if thats not it you could also take all the bulbs out and then put a fuse in if it doesnt blow well then your on to something at that point start putting in 1 bulb at a time till the fuse blows dont for get your visor lights. hope this helps

oh yeah i forgot to mention this. check your cigarette lighter make sure they work. if they dont look inside them make sure no loose change got stuck down there. i have seen this way to many times. i know this would be a really easy fix but most the time we over look the obvious. good luck

Thanks again, I took a stab at it this weekend and I took the truck even further apart, checked the door wedges and and i didnt forget the sunvisor lights or the cigarrete lighters, I plugged in the circuit breaker after all the light were disconnected and the inadver power relay began to buss so I removed the relay and replaced the fuse and IT DID NOT BLOW, I checked the lights and they still didnt work checked my sunroof and NOW tHAT WORKS. some progress but i still dont have lights I found out that the relay wire feeds into the BCM. but Im kinda lost now? any suggestions? Please Help
