On a 1990 Chevy astro how do you check the blower motor to see if it is bad?

The most conclusive test of a blower motor is to run a wire from

the battery directly to the motor, being careful not to ground the

wire out anywhere by accident. If the motor will not run when wired

directly to the battery, it is probably bad.
