battery drain

  1. 02-09 General Tech Q&A
    I have read the threads- but is there anything new as far as parasitic drain before I start troubleshooting? I tried pulling the OnStar fuse with no luck. Going to try the TBC-2 fuse tonight, but if that's it what is the repair? It seems to control more than the dome lights since it is a body...

    So we are experiencing a 'clicking' sound that is not really loud from the driver's side door post (the post where the door latches) when the car is shut off. You can put your ear to the plastic post material and here it clicking. It is not hot, but it does seem to be draining the battery (will...

    My tb is really weird its got a slow draw in it somewhere, sometimes it'll kill the battery in two weeks, sometimes one day or maybe a month. I have no idea what it could be and i just put a brand new optima red top in it. Anyone have any idea or have had the same problem??

    The front driver’s seat of our 06 Envoy has stopped working. The memory option doesn't move it, the buttons on the side do not move it and the heated seat option doesn't work on either front seat. If you push the buttons to move the seat or push the memory/exit buttons, the seat sits still but...

    This is my first forum post, and I am about as good with computers as I am with this car. Bear with me. The battery was running down over night. Removing the radio fuse (a 15 amp fuse in the rear fuse box) after the car has sat for an hour results in a 3.2 amp drop. This is not the whole...

    I have an 02 Trailblazer with a battery drain problem. I have isolated the problem to the TCCM or something connected to it. When the TCCM is unplugged the problem goes away. Has anyone else had this problem, and if so how did you fix it.
