2000 Suzuki Swift Removal & Replacement of A/C Blower F

I recently purchased this vehicle. When my mechanic refilled the A/C, he discovered that the fan {speed} control for the A/C and heater fan only works on the highest speed. Since the fan control controls whether or not the the A/C is working, it will be necessary to replace the fan control module. It has already been ordered and was reasonably priced. I need to know how to dismantle that portion of the dash which must be removed in order to replace the defective unit. Neither the local library nor the parts stores have that information. Please give me some info. Thanks
