I mentioned the blue power wire. After looking at the wire schematic, it apears that mine has been rewired in the past. It should be 14Brown and wired to the back of the fuse block. http://www.geocities.com/chevroletc1070/wiringdias.html
To access the core and blower you need to remove the pass side hood hinge. Don't forget to mark the hinge for realignment. You can remove the fan from here. If you want to remove the core, you need to drop the inner fender to remove the plastic case. You may have some leaves or some other crap in the blower cloging it up.
Hope I helped.

Your switch may not be wired right too. If you don't have the right wires to the switch, your blower will not go to high. Check them against the wiring diagram. Jeff.
