This is an easy job. The blower motor is located under the passenger side dash #60 in the picture below. Remove the screws, disconnect electrical connectors, remove the blower motor. Clearance may be a little tight. I can remove the blower motor on my 1995 truck without pulling back on the dash, but some of these trucks it is necessary to remove the bolt at the lower corner of the dash and pull the dash back slightly to get the blower motor out.
