I have a 2001 tahoe that continually kills the battery overnight. I have tried pulling all fuses and relays and the drain stays constant. My question is does the Tahoe have a continuous drain from the on star and the radio memory etc. and what else should I try to find the problem.E

check your underhood light. see if it is staying on. measure your current draw.  does it have a rear wiper
