Saab Problems? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
You certainly can check the motor.
When it is not operating properly use a paperclip to probe along the wire and a voltmeter/testlight to check for power at the connector. If you have power in but nothing on the other wire it is the motor. If you show 12 volts on both connections then it is not the motor but elsewhere in the system. This test is done with the key on and the blower switch on the high selection.
