You can pull the blower motor without pulling the dash... three small 8mm screws fasten it under the passenger side glove box. the blower resistor is tucked up just in front of it, track the wires wrapped in plastic mesh... Will take a little wiggling out... but it will come out...

 

Unfortunately, not a chance pre-2001. The blower comes in from the firewall (front) side of the HVAC housing, not from underneath, like in '01+.
