Tip & How-To about 2004 GMC Envoy

Parasitic battery drain - likely source

Check the number 07 fuse under the rear passenger seat. It serves the Truck Body Controller 2 (TBC 2). The controller fails & is a known source of intermittent battery drain. The will not be blown, it is just serving a bad controller that is not turning things off as it should.

99 chev blazer, service 4wd light is on. Simple things to check before the mechanic


There are a couple of fuses you will want to check. They are located in the under hood fuse box. The TBC ( truck body controller) and ATC (automatic transfer case) fuses.
If both are good, take the truck to your local Auto Zone and ask them to scan the vehicle for "trouble codes". Write the codes down and respond back.
Below is a diagram of the under hood fuse box and the fuse locations.
