Greetings all,

I've got a 99 Yukon 5.7. I noticed the other day that the 2wd/4wd selector switch lights were out. Found fuse 24 blown. Replaced it, and it blew again on start-up. I unplugged the 4wd actuator on the transfer case - same results. I unplugged the selector switches - same results. I've got continuity between the fuse 24 output and ground with the switches and actuator unplugged - so it seems like I may have a short...but I'm not certain since I don't know what else the wire feeds (not covered in the schematics of my Haynes manual). I've traced the wires from the actuator and the switches as far as I can, and found no obvious signs of wear or stress. Anyone have any suggestions?

Thanks in advance, -Dave.
