2002 Yukon Denali power failure

[quote:a8b75a27d5="Damon Chapman"]hello, my yukon denali has a power failure. When I put the key in yesterday my instrument panel and gauges light up and went out . Now when I turn the key I get nothing no lights, locks not responding to the remote. I tried to give a jump start no successs. could it be just a fuse?[/quote:a8b75a27d5]

I bet you have a lose battery cable or bad connection to the battery, you may want to check the connection and make sure they are tight and in good condition. I had the same problem in my truck and all it was, was a bad battery cable terminal and I had to fix it so that it had a good connection. Hope this helps.:D
