  1. I have a 2003 Chevy Silverado LS 1500 5.3L Gas Extended Cab Longbed and am having a weird battery drain issue. After sitting for about a week in 65 degree temps (or two to three days in freezing temps) my battery will be completely dead - like I can't even operate the door locks it's so dead. I started having the issue about 1.5 years ago and replaced the battery, but that didn't fix the issue... A few months ago I went out and peered into the drivers side window to find that the readout on my instrument panel (where the odometer reading, hourometer and tripometer is displayed) was completely illuminated (see picture below). This was after it had been sitting for at least a full day. As soon as I unlocked and opened the door, it went out. I have seen this many times now. I've had the truck for almost 5 years now and the only thing I have done to it is the installation of a radio about 4 years ago. It all seems to function great, minus the battery drain. Ideas? I have the Ghost Busters on speed dial if needed. UPDATE: I just did a parasitic battery drain test and found that it was pulling 0.25 A when sitting and would occasionally jump up to and sit around 0.6 A. I pulled the IPC/DIC fuse and it drops to 0.004 A. So, I'm getting warmer... I also pulled my aftermarket radio out and found an Access GMOS-01 harness. Could this crappy harness be causing the problem? Is there a way to test it?
