You can do that. Look at the harness for a brown wire. The corresponding terminal on the motor should be grounded, with 12 volts to the other terminal. It should run either way, but correct polarity will duplicate normal operating conditions.
If it doesn't run, give it a tap around the brushes. If they're worn down that might cause them to make contact.
