I would replace the blower motor resistor. Also make sure the small black hose that cools the motor is installed properly.

Answer

If the blower operates on all speeds, the resistor is OK. If you have had 3 motors fail in 3 months, either there is something different wrong with the resistor, or you are buying the wrong brand of motors.

Check the terminals inside the connector for and damage or signs of overheating. Cutting out like you said will cause rapid motor failure.

The terminals will be blue and possibly bent out of shape. If this is the case, you need to place the connector.
