Default 97SE Blower Motor Speed Switch problem.

My 97SE has the "base model" hvac controls with the 4-position **** to control fan speed. Going from left to right, let'* call the positions 1,2,3,and 4. For several months now, something is wrong with mine, where 1,2,and 4 work normally, but 3 is the same blower speed as 4, except for a very little tiny zone almost between 2 and 3, where I get what should be the 3 fan speed. The click points have not moved, the switch still click centers in each position, but when centered on 3, I get the same high fan speed as 4.

Ideas? My only experience with these things is with blower motor resistors having one or more of their elements burning up, which causes one or more positions to have no fan speed. That doesn't seem to be the case. I have no idea what might be causing this.

97 SE, teflon wiper blades, Dunlop Sport A-2 tires, Leather steering wheel cover, Pioneer DEH-P480MP mp3 CDRW head unit, Pioneer 12-disc changer, iPod hookup, Boston Acoustic 3 way 6x9'*, Boston acoustic separates in door pods, Alpine 4 channel amp in trunk. Magnaflow dual outlet muffler and Ractive stainless tips. Autozone rice pipe and K&N 4750 intake kit. Clear corner lights. Energy Suspension end links.
