Please let me know if you found your problem, this is about to drive me nuts.

havent been here in so long.hope this makes it!hi! no i have not had any luck.mine does have a parasitic draw but it comes and goes!the truck is sos bad now i have ruined the 2 batterys that are in there now,why you might ask? well the battreys are weak form constant full charge then drained to dead battery! when u get a fast charge on a battery it caues plate deterioration.so the reserve battery life just gets shorter and shorter.i i ahd to install a quick dissconect under the hood.when we get out of it i raise the hood and pull my quick clip cables and kills all battery power to the truck.now its gotten so bad if u dont unhook the power just going inside to wallmart for 30 mins the batterys are dead when when we come out.then some days or some weeks we will forgetto kill all main power it may go 2 3 4days and not have an incident. new problem.my day time running lights dont work anymore,go figuer! i am an ex mechanic and one of my specialtys was finding dead draws such as this but i have had no luck! i had another post somewhere, i cant remember where!he has the same exact issue as we do same year same model. someone told him it was the body control module.i never heard any more from the guy! i cant find the body control module.everone says its in the center console but i found out thats just in the yukon denalli! to make a long story short they want 70 bucks an hour to try and run it down.i dont have it and i never will have that kind of money.and i dont even have the crappy cd player in the truck anymore.i am looking for a master switch i can mount in the fender so i can cut power without having to open the hood.well thats what i found theres somemore info on the subject.we arent alone in the quest to fix this issue i found atleast 4 other people with almost identical issues!if u find out where the body control modual is ,drop me a line please. any other questions or ideas let me know! bob at [email protected] .good luck!
