To replace the cabin fan on a GMC Sierra, unscrew the screws securing the panel located directly under the glove compartment on the passenger side: once this panel is removed, unscrew the screws holding the cabin fan cover, which must be disconnected from its connector and removed from its housing.

Once the old fan is removed, you can install the new one, connecting it and placing it in its slot while reinstalling all previously removed components.
