Hello,
I have a 2000 Tahoe that has seemed to come up with some issues. It's the newer model of the 2000 year model. Anyway I've all of a sudden got a battery draw. It will completely drain my battery over night. If it does drain it all the way and I hook a battery charger to it I start getting a loud clicking noise from the left side of my dash by my light switch. This clicking has only happened twice and both times it has blown both of my low beam headlights. Not sure if it is the light switch itself or what is causing this, so hoping someone has had the same issue and can help out.
