The main fuse for the Rear AC blower is a 40 Amp called RR A/C in that box. Also could be the RR A/C Relay.The power and control circuit for the rear blower is the same for the Automatic or Manual systems.

There is another relay in the engine compartment junction box labeled HTR which runs the Front Blower. They are identical. Swap them, if your problem moves to the Front Blower its the relay. If not then you know both relays are OK.

Hope that is helpful.
