I feel like a jackass for asking this, but my brother-in-law has my hayne's manual and search got me nothing. The heater/ac blower motor was going out in my wife's '93 so I went to the junk yard and got a replacement. The new motor plastic wheel is broken so I need to swap it with the original. It has a clip on the motor shaft which I removed, but can't get the wheel to come off. I soaked the shaft end with triflow but can't get the wheel to budge. Does it simply pull off or am I missing something? Any help would be appreciated.
