Blue Streak® is proud to offer premium Blower Motor Resistor Kits as a high-quality solution for melted connectors and blower motor resistors. Blue Streak® improved on the OE design to create a connector that will withstand the excessive heat and reduce future failure. Our connectors undergo thermal cycling testing to withstand extreme temperatures to prevent melting. Blue Streak® offers blower motor resistors that are direct-fit replacements and engineered to withstand the high amounts of current that can melt the resistor or connector.

TXL copper wiring withstands high electric current to reduce heat-related failure
High-temp connector withstands extreme temperatures to prevent melting
Blower Motor Resistors control the electrical current flowing from the fan switch to the blower fan, which allows the motorist to set the fan at different speeds. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system.
Due to technological advancements on today’s automotive heating and cooling systems, blower motor resistors have high amounts of current running through their connectors. As a result, the current produces heat that can melt the connector and resistor. Worn OE blower motors can create a demand for current that also damages the resistor or module. The excess current melts the wiring and plastic shroud, damaging the interface pins on the controller’s circuit board.
For repairs, use an inductive amp clamp to check that the blower motor current draw is less than 80% of the fuse rating on high. If the current is too high, replace the blower motor. Otherwise, the new resistor will fail too. You should also inspect the mating connector for signs of damage caused by excess heat.
