even more probs with 4x4
so u all should have seen my millions of posts on here but i did everything i can to diagnose the prob and i thought i had it down to the computer but today after the truck was sittin for one day i go to start it and it is completly dead...nothing was on..so something is draining the battery and i cant figure this one out it takes 30 min to get her to crank,hooked up to a 2006 trailblazer, as it started to get some juice in the battery the thing near the passengerside door clikced constantly truck with the key in on or out but once it started it went back to 3 lights flashing and no clicking so i let it charge for a good 40 min shut it off and it started up about n hour later it was dead again...do you guys have any idea what this could be i thought a computer but if a computer went it wouldnt need battery juice right? and since it clicked today it seems as tho the computer is fine or what ever it is under there. im also stuck in 4lo thats y i think all this started

If the battery and charging system is good. It is time to start testing for a short. get a volt/ohm meter and check the amp draw. If something is shorting or pulling to many amps start disconnecting until you find it.

Re: even more probs with 4x4
Why dont you just unplug the TCCM and see if you still have current draw with the key off. It sounds like the TCCM is still trying to engage 4wd when the key is off.
