My auto locking is not working, it seems that there must be a short or a fuse out. I also noticed that the radio use to stay on when the key was turned off and now it does not. there must have been a small electircal current that ran everything and now does not seem to be there?

possible short. backtrack the ignition wiring that you replaced.

BCM shorted out when your wiring shorted

Hi! This doesn't sound like a shorted wire, because a short would usually blow a fuse. Since you're having trouble with the starter, I'm thinking that the ignition switch needs replacement. Depending on the year/make/model, you may be able to change just the electrical part of the ignition switch.

Sounds like you have a short to power. there are several wires that connect to your radio and console . one is the ignition wire that kills power to the radio and console when the key turns off. What has probably happened is that wire has found a constant power source from another wire and it constantly stays on. finding this short is very difficult because it is under the dash so you might want to take it to a professional. Also if the van has the feature where the radio doesnt cut off until you open the doors, then your short may be somewhere in the sensors on the doors.

check fuse and power to radio also ur key might be causing the problem or key cylinder the radio has a built in anti theft system some aftermarket and worn down keys set off the theft deterent or bad key cylinder or theft loc on radio activated have ur truck scanned some auto stores such as auto zone / advanced auto scan for free it will give u a start point

check for a shorted to ground positive wire repair as nesseacry

remove coins from the cigarette lighter or unplug it. Never put a bigger fuse in than what it calls for tha is a BIG mistake.

Nothing wrong with it. When you remove the key, it stays on for about 20 minutes. It gives you time to finish listening to your radio and roll up the window. Once the driver door is open, everything shuts off or if 20 minutes has passed. 
 
 

I have recently had this problem I believe this to has been caused by a fault in the drivers door lock assembly It seems this contains the remote receiver. In my case I think there had been some radio interference being the main cause. The remote system seems to be working OK, The door lock will still not operate with the key.
Remove and replace the fuse 25 resetting the ignition module. Starting the engine, switch off remove the key from the ignition, stay in the car lock the doors using the door button, press and hold the remote unlock button for approx 5 seconds, listen to see if you can hear the clicking of the door receiver when you press the remote buttons. Press and hold lock/unlock button. You may be lucky.
