A/c heater blower motor trouble

Hi i am having trouble with my 1992 eldorado a/c heater blower(no air flow hot or cold through the front vents). the blower for the rear vents is working fine. i checked the fuses(1 40 amp maxi and 1 10 amp fuse under the hood both look good. i hooked the front blower directly to the battery and it turns on and runs. im sure the climate control panel works because when i push warmer or colder i can hear and see the air door open and shut. i removed the resistor(next to the blower motor on the fire wall) and there is no visible damage so i am stuck please help.?

Resister? That car doesn't have a resister. It has a blower speed control module that is likely your problem as Cadieman pointed out.
