I am sorry your having this problem'what has to be done and is somewhat time consuming is a draw test needs to be done to see if its drawing over 50 MA

the odds are it will be then one fuse is pulled at a time until the draw goes down below that spec and what ever is on that fuse is causing the draw

we have seen radios and BCM's and dash clusters being the big problem with these causing this kind of draw

with a new battery and i am assuming the charging system tests good that is the direction you need to go next i am sorry to say

if you have any questions please ask as i do mot get credit for my work until you rate us here at Justanswer
