@theartistq that is a tricky one. If your blower motor resistor continue to fail you do want to do a few things. First check the amperage that the new motor pulls. If it is to high then there are issues with that. After that you do want to check for corrosion on the wiring and connectors since that can cause heat which may cause failure. Next is to check the airflow to ensure that it is unobstructed. Leafs, mechanical obstruction, water as well as other debris can cause overheating/shortening out of the resistor. Check for anything unusual at this time.

Make sure that it is not the switch that shortens it out. Check for anything unusual at this time.
