My 72 with A/C has all 4 fan speeds, but 3 seems slow. All 4 of the fan speeds work, but you can hardly feel or hear it increase much from the 2nd to the 3rd speed. High blower relay is fine and blows hard.


Is there a way to test for this? Could this be a motor problem or a switch problem? Or are the 2 and 3 speeds just very close to the same?
