    Bad blower motors usually burn out the resister pack that controls the speed of the blower motor.

    It's unusual that the blower motor is going bad that often.

    You need to check the ground wire or run a new one to the motor.

    I'd replace the resister pack and the motor at the same time just in case the resister pack has corrosion inside that is messing with the blower motor.

    What brand blower motor are you buying?

    Buy a Dorman blower motor from Advance Auto and give it a try.

    Check the voltage on the hot wire to the blower motor, its probably too hot. If so bad switch.

      If you have tried 4 different blowers the odds are very high it's not the blowers themselves.
