All information and pics are from the 1990 Section 8A Electrical Diagnosis Supplement. I can't say what is needed for anything after 1990 ( but I assume 91 should be the same), but on a 1990 there should be a 25A fuse, not 10A on the A/C fuse space.
P.S. If you look on pg 8A-66-1 of the pics I gave you, you'll see there's a 5A A/C underhood fuse on the line that gives input to the heater/ AC programmer from the output of the blower power module. There is also a fusible link that feeds the blower control module. If the link is completely blown, the blower will not work (I'm assuming the heater programmer will not work properly without input(voltage) from the blower power module output, which is protected by the 5A fuse).
