On a 2004 Chevy Colorado, the heater relay is typically located in the under-hood fuse box. To access it, open the hood and find the fuse box, which is usually near the battery. The relay should be labeled on the diagram inside the fuse box cover, often designated for the heater or HVAC system. Always consult the owner’s manual for specific details related to your vehicle.
