1995 cherokee hvac not working

1995 cherokee nothing on the hvac works. I have checked the fuses, the blower fuse was blown I replaced it and still nothing. jumped the blower motor to the bat and it runs. I pulled the hvac control out there is a little rust around some of the wires. I pulled the blower motor resistor out it looked fine just a little rusty. what else should i check??

There is also a fuse in the pdc - no 6
