Have you checked/changed the brushes in the blower motor? I have been told by several on this board that the fan will sometimes blow fine, other times hardly blow. Also, when the brushes get so far worn down, sometimes the fan will quit blowing all together. I am having the same problem as far as the fan blowing sometimes hard and other times not much at all. I have bought some new brushes, but I can't find the blower motor to replace them. Would you happen to know where it would be. I have looked behind the passenger side panel(behind the radio/heater controls) and cannot not find the motor. I did see a black unit that some plugs went into there on the passenger side and wonder if the motor would be inside this unit? Any help would be appreciated.
