The Chevrolet S-10 had been General Motors compact truck for more than 25 years before it was discontinued in 2005. For years the S-10 came with a wide range of available options, from four-wheel drive to engines such as the 2.2 liter four cylinder, the 2.8 liter V-6, and the most popular, the 4.3 liter V-6. In 1998 this model was available with either manual or automatic climate control. The automatic system allowed for a computer to control the temperature inside of the vehicle. This was a nice feature, but repairing either one of these systems could get expensive. Being able to service parts of this system yourself could easily save you money.
Park the vehicle on a flat surface. Set the parking brake. Turn the ignition key off and remove the key from the vehicle. Open the hood. Locate the blower motor resistor connector on the passenger side of the engine compartment firewall. The connector will have a light blue wire, a brown wire, a dark blue wire and a tan wire. Disconnect the connector by lifting on the retaining clip.
Remove the three mounting bolts from the resistor. If the vehicle does not have factory-equipped air conditioning, you will not see the mounting bolts. Cut a square approximately two inches around the connector with your utility knife until you can access the mounting bolts. Remove the resistor from the vehicle.
Install the new resistor and torque the bolts to 17 inch-pounds with the torque wrench. Apply a large bead of Black RTV Silicone to the area that was cut without leaving any open gaps. Install the connector until you feel it snap into place.
