How to test blower motor module in 95

The auto climate control worked intermittently for one day and than the fan stopped altogether. Does anyone know what test I would use to determine if its the blower control module or the actual head unit itself. I checked all of the fuse (including under the rear seat) and they were all good.
Thanks.

Easiest test without getting to involved is to just turn on your blower motor. Then tap on the blower motor lightly with a small hammer. In most cases if it is the blower motor it will start running again, but that a very good sign they have shyt the bed.

Blower motor is fine. I disconnected the supply from the Riviera and threw 12 volts from another source and it started blowing immediately. Is their a way to test the control module? Also I see a lot of modules available with the same pin pattern but different mounting patterns that fit other GM products, I would imagine these would work but would like to know if anyone else has tried this approach.

I found one on eBay for $35 with shipping from DKIautoparts. Hopefully it works longer than a week but for the price I couldn't pass it up.
