Blower problems need help?

[larryboz]

I have got a 86 3/4 ton, just bought it. Anyway I went to turn on the vent and turned the speed to high and nothing. Nothing blows out at any speed. Vent, heater A/C, or defrost nothing works. I am not electrically gifted so where would a good place to start at. I am thinking of replacing motor because it looks original and then maybe replacing the control unit. If any of you had this problem let me know what you did to fix this I am going to need it when it gets cold.

Thanks

Larry
