In a 2007 Chevrolet Avalanche, the blower motor fuse can be found in the engine compartment fuse block on the driver's side. Specifically, it will be at position 73, which is a J-Case fuse located near the bottom left of the block. You will notice four J-Case fuses grouped together, and the blower motor fuse will be in the bottom right of those four. If you find yourself replacing this fuse repeatedly, there may be underlying issues with the blower motor wiring causing it to blow out. Fuses are designed as a safety measure and shouldn't burn out on their own, so if this happens, there could be a more significant problem that needs to be addressed.
