    Sounds like the motor is beginning to sieze up, you might want to find someone who works on AC/ swamp cooling units pronto.

    Possibly the blower is the kind with a drive belt– you know: two pulleys, one on the motor and one on the blower with a V-belt to transfer rotary power from the motor to the blower wheel. If this is the case I would examine the condition and tension of the belt first. Just turn off the power to the unit, lift out one of the side panels and take a look. If the belt and pulleys are ok it most probably is the motor or control wiring. If you’re not experienced call a pro at this point.
    If it doesn’t have a drive belt and is in fact a direct drive unit, the blower may be loose on the motor shaft–which might be as simple as tightening the set screw. Good Luck!
