Where is the block heater cord on a 2005 Envoy?

On a 2005 GMC Envoy, the block heater cord is typically located near the front of the engine, usually on the passenger side. It may be routed along the engine block or tucked into the front grille area for easy access. If you can't find it, check under the hood near the engine or look for a small three-prong plug that may be hanging down or secured to the frame.
