I have a parasitic battery drain problem which lowers when fuse 31 is removed on the inside fuse panel. This controls the main light switch and the lighting control module how do I diagnose from here?

The draw is 5.8 amps it lowers to 2 amps when fuse 31 is removed under the dash. When I removed fuse 19 in the fuse panel under the hood the draw went down to.5 amps. This fuse feeds sub woofer, i/p fuse panel, fuse 23. I assumed this draw was due to the stereo coming on every time the battery is disconnected and reconnected or am I wrong.I tried unplugging the light switch and that blew the fuse in my multi-meter. I then tried hooking up the battery and the lights came on with no switch plugged in is this normal?

It sounds like you have a lighting control module that has shorted out. Here is the location so you can swap it out.

Yep you were right once I unplugged the lighting module the voltage draw stopped. Thanks for the help I can believe this site is free.
