Yukon had no power, no door locks, no lights, no radio, no nothing. Installed a brand new battery thinking this was the problem. Still absolutely nothing. Not even the cigarrette lighter. What could it be?

thank you

Most likely the problem lies in the battery connections. Turn on the headlights and then wiggle the battery cable wires and see if you can get the lights to flicker on and off, if they do then you will need to replace the battery cable ends.

I tried that but the battery was drained. I put a new battery in and in drained immediately. The cigarrette lighter doesn't even work.

Is something shorting or a fuse blown? I check the fuses and they look okay.

Thanks

If you installed a new battery and it drained immediately them most likely the battery was bad or you have melted wires somewhere.
