There's a second fuse box under the back seat on driver's side.

SOURCE: My 2006 GMC Envoy won't start and the battery is good and all the fluids are full, how would I locate the starter to check to see if that was the problem?

ne side starter is mounted against the face of the transmission on oof the engine (usually on the right side) Under the car. There should be 12v at the main lead and 12v at the small (trigger) terminal when the key is turned to the start position. If no power there, check neutral switch and ign switch. You also need to check and verify 12v at the battery and that all connections are clean and secure at both ends of each cable.
