The 2006 Chevrolet Colorado pickup shared a platform with the GMC Canyon and was available in two- and four-door versions. Powertrain configurations were a 2.8-liter in-line four or 3.5-liter in-line five-cylinder engine, four-speed automatic or five-speed manual transmission and two- or four-wheel-drive. The blower motor resistor controls the lower fan speeds for the heater and air conditioning. Unlike many other vehicles, the resistor is fairly easy to access and replace in the 2006 Chevrolet Colorado.
Park the Colorado on a level surface and set the parking brake.
Disconnect the negative battery cable with a wrench.
Move to the passenger compartment. Pull up the door sill from the bottom of the door. It is held in with tabs and clips. No tools are needed.
Pull the plastic panel from the bottom of the dash. It is also held with tabs and clips. Confirm that you see the blower motor and resistor. The resistor is just to the left of the blower motor. It has a connector with four wires on it.
Pull the connector from the resistor. Use a nut driver to remove the two hex-head screws from the resistor. Remove the resistor.
Slide a new resistor into place. Install and tighten the screws.
Plug in the electrical connector.
Snap the bottom panel into place. Snap the door sill into place.
Reconnect the negative battery cable.
