Question: Heater Controls "stuck"?

When I start the car, there is a noise that sounds like an air pump coming from the frond dash. The air that comes out is not hot, regardless of water temp. Could there be a motor or vacuum positioning that controls the vent for comfort heating?

Your response was right on the button. I went today and they found a "air mixing actuator" was not responding. Cost of the actuator was 165.00 and the labor was 150.00. The actuator was inside the dash behind the glove compartment..... a real booger to get to and NOT a job for me. Thanks for the help.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
