Electrical issue

[bnorris711]

Someone please help! My power windows and windshield wipers in my 02 Tahoe continue to work with the key out, door open, and after the 10 minute delay. I have checked every fuse, relay, and even replaced the BCM to no avail. This is draining my battery horribly!

If you havent done so already, remove and clean the ground connection at the top center rear of the engine block.
