Ok so I've been through the whole system as far as I know. I've checked every fuse.( including #20) I went through the whole heating a cooling system a few months back. New heater core new blower resistor radiator water pump the works. Everything was working fine then all the sudden the blower just quit working. So I went through everything. Put power to the blower to make sure it wasnt bad. Works fine. When checking for power it appears I dont have power getting to the resistor when I check for voltage at the resistor plug. So I then replaced the whole dual climate control unit in the dash. Still nothing. I'm at a loss for what is wrong. Anybody got an idea?

 

The only thing I can think of is with the dual zone climate control heater the blower resistor isn't a resistor. It's a solid state speed control relay.
