If the fan motor in your 2005 Silverado only runs on high speed, it could be due to a faulty blower motor resistor, which controls the fan speeds. When the resistor fails, the motor may bypass lower speeds and only operate at high. It's also possible that there is an issue with the climate control module or wiring. Checking the resistor and related components is a good starting point for troubleshooting.

To wire a four-lead 12-volt blower motor switch, first identify the terminals: typically, there are two for the power source (input) and two for the motor (output). Connect the positive wire from the power source to one of the input terminals, and the negative wire to the other input terminal. Then, connect one output terminal to the blower motor and the other output terminal back to the power source's negative side. Ensure all connections are secure and insulated to prevent shorts.

To replace the heater core in a 1989 Dodge B250, start by disconnecting the battery and draining the cooling system. Remove the dashboard components to access the heater box, which typically involves taking out screws and clips.
