Unlock1 fuse

2008 3500hd crew The circut for unlock1 has a parasitic draw of about .220 amps. When I pull the fuse it goes to .002. Anyone have any idea what would cause the draw?

See the attachment. Something is probably keeping it active. This is the only page in the 2008 manual that refers to unock1.

What lead you to this device?


I hooked up an amp meter in series and started removing fuses one by one. When I pulled this one I got the meter to drop to .002. There is quite a few fuses. Thought it was going to be the radio or cluster. They seem to be the common problem.

Thanks for the drawing. This will help me out. I was hoping someone else had this issue.
Won't let me view it. Says there's a server error?
Website seems to have a problem so I'll post again


Thanks Ron. Got it that time. It seems intermittent. Just checked again and it was okay. I wish it would stay broke. Much easier that way.
