Unhappy A/C No Blow

I own an 87 chevy caprice. The A/C no longer blows but the compressor comes on. I replaced the Fan Motor relay but still
nothing. I believe the fan motor is bad.Is there anyway to test
the fan motor after removing it? Thanks for your help

A possibility is a bad resistor.

If you bring direct power from the battery to the fan motor and it spins---look elsewhere, the problem would not be the blower motor.

bring direct power AND GROUND to the motor connector.

most cars i work on(not chevy) have power on one terminal of the motor all the time, the ground side consists of the switch and the resistor.
