Problem identified. Driver side vanity mirror left hinge broke and the light was staying on. What a relief to finally sort that out.

So whats the draw on the battery now you found your problem.
I have something killing mine overnight had a new battery in november till a week ago now another new battery and my vanity lights in both visors are unplugged no light on inside. Alternator diode checked out good. Its fine if you start it every 8 hours leave it 12 and dead..dome override pushed and hood light disconnected also when connecting my positive cable onto battery the ac compressor clutch engages and clicks but heater/ac is off and keys in my pocket and it don't disengage is that normal ?? thinking about unplugging the ac compressor to see if thats what is killing my battery off ..i have noticed my battery gauge don't go past 14 stays at 12.8 ish with the new battery while driving it ..it use to go a little past 14 before with old battery ..smh
