My 1999 Buick Century blower fan only worked when on HIGH setting so I REPLACED the heater blower motor resistor. All other setting worked fine for a day. Now it only works on HIGH again. Any suggestions what the issue may be?

the reason these burn out is either the connector is melted and overheated or the blower motor is pulling too much amperage overheating these items.
