About this part

If the Colorado's fan works on high but not the lower speeds, or quits on some settings, the blower motor resistor is a common cause. The resistor controls fan speed and runs hot, which over time can burn the plug on the harness. This Dorman kit includes a new connector with the resistor. That lets you repair a heat damaged plug in the same job.

Fitment notes

Part 973-434 is listed for the 2005 Chevrolet Colorado. The row gives no trim or climate control limit, but automatic and manual HVAC systems can use different parts, so compare your old resistor. Confirm your truck in the fitment table above, or send us your VIN before ordering.

Installation notes

Disconnect the battery first. The resistor is usually behind the glove box or under the dash. If the old plug shows heat damage, splice in the included connector. Check that the blower motor spins freely to protect the new resistor.
