1997 Isuzu Rodeo Question Heater blower doesn't work

I can't get the blower in my '97 rodeo to work. I pulled the blower out and hooked to a battery and it works fine. So I'm obviously not getting power to the motor. I checked the fuse and it's good I switched the relay with another that "looked" the same and still nothing. I then pulled the dash apart and unhooked the plug from the fan switch and tested the wires and found no power with the key being on or off? Any Ideas where I could be losing the power? There's power to the fuse and power to 1 of the 4 terminals on the relay does that sound right?
