To replace the resistor heater blower in a 1994 Chevy van, first disconnect the vehicle battery to ensure safety. Locate the blower motor resistor, which is typically found near the blower motor under the dashboard on the passenger side. Remove the screws or bolts holding it in place, disconnect the wiring harness, and then replace it with the new resistor. Reassemble everything, reconnect the battery, and test the blower to ensure it operates properly.
