Bypass AC Controls to test System?

[dimeified]

My fan speed control is rusted frozen. Im sure even if i could turn it, the contacts are probably too shot to make any kind of connection to start the system. Before i go and order a new expensive control, is there any way to jumper the ac system to at least see if it functions? It hasnt worked since i had the car. I searched around but couldnt find an answers.
Thanks.
