phillips4818 Posted October 3, 2008 Report Share Posted October 3, 2008 I've got a problem that's eating my lunch. The battery drains overnight. First thing I did was replace the battery. The problem remained. I took it to my mechanic, not a dealer, but a very experienced professional. He removed the body control module, and the battery still drained. After much troubleshooting, my mechanic determined that the BCM was receiving a signal that the ignition switch was always in the "accessory" position. He removed the ignition switch from the circuit, and the condition remained, the BCM was still receiving a signal that the switch was in "accessory" position. So that's the problem. Doesn't seem to be the BCM or the ignition switch. Does it sound like a simple short in one of the many miles of wires in the car. Help! Link to comment Share on other sites More sharing options...
