2001 Chevy Venture 6 cyl Front Wheel Drive Automatic

OK let me say first that I havent done alot of troubleshooting in this issue yet but I was wanting a second opinion before I spent alot of time in the wrong area.
I have a 2001 Chevy Venture that belongs to my sister. Last week the power windows, power locks, instrument cluster(Lights and Gauges), and the interior lights quit working. Then a day later the radio went into lockout. On originally looking it over I noticed that the batter was leaking battery acid so we replaced it and cleaned all connections. When we started the van again the radio worked for a few seconds and then went into lockout again. At this time I tried to plug in my scan tool to see if I could pull any codes out of the PCM or BCM. To my surprise my scan tool would not power up. I checked for voltage on the DLC and have less than 2 volts instead of battery voltage. Also I can not find a ground on the DLC. I am thinking that I might have either a bad ground. Bad fuseable link? Can the Body Contol Module create a problem with the DLC? I can give more information as I start to test some things out but I was looking for a little input or thought maybe someone has run across this issue before?
Thanks,
Bill

If you have no power at dlc I would suspect blown fuse but I bet you already checked that. Next I would look at the ignition switch not sending ignition voltage to those affected areas, thats most likely your problem. Hope this helps

Tim,
Yes I did check all fuses both in the right side of the dash panel as well as all fuses under the hood. Thanks for the input on the ignition switch. I hadnt thought about that, but I will bet you are right!

I talked to a guy today that told me he had run into a few GM vehicals that had corrosion issues on the back side of the interior fuse panel that caused issues like this. Have you ever run into the corrosion issue?

Well once again thanks for you input!

Tim,
Thanks again for you input! My sister is bringing the van back to me again in a day or so. I will stop back and let you know what I find.

Tim,
Just wanted to let you know that I did figure out the problem. I wanted to post this just in case anyone else in the forum ever has the same issues.

Under the hood on the right front corner is where the relay center/fuse panel is located. On the bottom side of the relay center toward the engine side there is 4-6 power wires the run out of the relay center. The problem I found was on (1) of those wires. I am assuming that at one time or another someone had probed the wire with a test light or something else. The wire was corroded inside and the outside jacked of the wire was still in place but the wire itself inside had actually corroded in half? It was not until I pulled on the wires one at a time that I found the bad wire.

Just wanted to leave a post with what I found so that it may help someone else in the future. Once again I would like to thank you for your help!

Thanks,
Bill
