Not sure what fuse controls rear AC but there s a relay specific to rear ac.heat only. It is in the fuse/relay box under the hood. Your manual should show the diagram. There are 3 similar relays in an L-shape on my 1999. the rear ac relay is the one at the base of the L-shape.
The Heater/Blower Relay is on the blower motor housing under the dash in the passenger compartment on 1999-2002 models
Bad fuse? Bad motor? Bad relay? Bad switch?
