Need some help on battery drainage

[jimmybeus]

Ok guys I got a question for you. I have an 02 yukon and the battery keeps draining some where. I had both the alt. and battery tested. Both are good. This morning I went to start it and again battery dead. Shut the door to go and get my charger and the door chime was still dinging. Opened it again took out the keys shut the door still dinging. Hooked up the charger quit dinging. Awhile back the heater fan wouldn't shut off after the key was off. Had to disconnect the battery. Do I have some short of lemon or has someone else experienced this and if so what did you find to remedy the problem? Thanks in advance.

there was a reflash for battery drainage issues but not sure if it went back to 02 or not may want to call your dealer and see if there is a reflash for it.
