Question about 2006 Chevrolet Colorado
Posted by Anonymous on
It's located near the fan motor on the passenger side duct work. It will have a harness plugged into it.
It's mounted with 2 sonic welds, to remove it pry under the mounting points to snap the welds. The replacement resistor is mounted with 2 self tapping screws.

Inspect the Wiring Harness Connector for any signs of overheating before replacing the Resistor. These connectors cannot withstand an Overload and usually fail before the Resistor. If any signs of Overheated Wires and/or Contacts are present then replace both the Connector and the Resistor Module. These components are usually available from After Market Suppliers. On rare occasions the Blower Speed Switch may fail as well. The Blower Motor Ground wire is in the Resistor Connector and a Relay is used for the Highest Speed. Said Relay is usually mounted so if the return spring fails the Contacts will be held closed by gravity and difficult to shut off. Pulling the Fuse is the only answer to this problem.
Check for 12Volts for each Blower Speed. The Resistor Module has multiple Resistors for each speed except High Speed which energizes a Relay to supply 12V to the Blower Motor. Speed Selection 1 selects All resistors in series, Speed Selection 2 one less resistor, 3 & 4 each one less Resistor. I don't know how many speeds the Colorado Blower has but the principle is the same regardless of how many speeds. I have a 2004 Silverado and have had to replace the Resistor Module 3 times in 140K Miles and the Blower motor twice. Michigan Winters are COLD and Summers are Warm requiring the A/C normally on High Blower speed.
Let me know what you ultimately find. Many times the Ground connection will be found to have some resistance due to improper bonding to the Chassis or Dashboard steel mounting. Remember that all vehicles are "Planned Obsolesence" and many manufacturing costs are reduced by using very poor quality Grounding techniques.

It's located on the passenget side under the dash in the area of the blower motor, it will have a 4 wire connector to it.

the resister is usually located in the air box above the passengers feet ,high indicates the resistor needs to be replaced

Testimonial: "Thank you for the help, you've saved me a ton of time and frustration."
SOURCE: ac blower motor
The blower motor resistor is located at the top of the fresh air intake (hard plastic hose going into the "box") You most likely have, or have had, water in your passenger side floor board area as well. The resistor is in direct line with one of the water leak problems on the 2006. I would bet that the "noise" you hear is trash, or debris in your fan motor housing. (might even be water)
Open your hood and remove the black plastic moulding from your lower windshield (remove the wiper arms first) there you will find a clear plastic sheet of polyeurethane. It is either missing or open enough for "critters" to gain access to your fresh air intake.

Tips for a great answer:
HEATER BLOWER MOTOR
faulty blower motor resistor. The low and medium speed on blower motor is
controlled by resistor and its actual speed is high. So because resistor is not
working, blower motors actual speed which is high is working.
can be faulty blower motor or faulty blower motor resistor. Get the blower
motor inspected. If it's faulty it has to be replaced.
blower motor testing and replacing, check the link below: ----
These will help.
