What's on TBC 2B fuse?

My 2004 Chev Silverado continually blows the fuse listed as TBC 2B. Some of the cluster lights go out but I was wondering what all is on this circuit to start checking for a short.
TBC means Truck Body Controller according to the manual. I'd just like to know if there's more than just the dash lights on this fuse.
Thanks tbc circuit has short that is draining the battery!

Incorrectly wired radio would cause problem.it would be the wire that is suppose to connect for dimming lights looks like a ground but is not has a yellow or a white stripe with black on it.use it as a ground and it will blow the fuse.

The dome lite on my 2006 gmc seirra will not come on cant find the fuse


Well it looks like the lights are controlled and powered by the body computer and a door module for each front door.
The fuses involved are marked TBC 2B and 2C and they are each 15amp. They are in the fuse box in or under the dash.

This fuse is for the body control module, so your draw is probably something controled by the bcm. Get a manusl, get a list, and eliminate them one by one until your draw is gone! Good luck, let me know if you need any more help!

Fuse box


Start by checking the TBC fuses in the door jamb fuse block. As far as I can see, that is where the inadvertant power bus picks up power which is what the lights feed off of. Good Luck.
