Dodge Repair: blower fan replacment, passive restraint systems, wheel hub

Question
I need to replace my blower fan on a 2000 Dodge Dakota with the 3.9l motor.  I can see it under the dash on the passenger side of the vehicle I see a few screws I can get to but there are other that look difficult to access.  Do I need to take any of the dash off ?  How would I go about this ?
