Power Cut Out

[florio80]

I have a 00 1500 Silverado, it has 118K miles on it and I am the only onwer. About a year ago I was driving it and suddenly all the power went out. The A/C, odometer display went completely out, the funny thing is the rest of the vehicle was fine, I could still hear the radio and the truck drove fine. I found out when I move the steering column up or down the power comes on or goes off again. Also sometimes when I engage the cruise control the power outage will occur.

 

 

 

I'm thinking its a short in the wire harness but not sure, any guess are greatly appreciated!

My best guess is the ignition switch. Do a quick search here and you will see it is an issue. The ignition switch in a 2000 has (I think) four circuits out. Things that are always powered such as dome lamps don't go through it. Everything that is only active with the key on does. One circuit through the switch for everything switch operated would be too much current for the switch to handle so they made four circuits that feed all of the switch powered fuses. What happens alot of times is one of those circuits has a little dead or high resistant spot so some switch controlled circuits will work and some will not.

 

When this is the case you will usually see a few systems come down at one time and come back all togeather like you seem to have. Bouncing the collum around can bounce the contacts around on that switch and get you temporarily working sometimes.

 

That's my best guess anyway.

Thanks for the troubleshooting, I will look into it. Are they very hard to replace?
