No Air on Defrost Setting
I have a 2006 Commander limited, and when I turn the electronic climate controls to defrost, the air immediately comes out the vents. I can hear the motor running and trying to switch but it never comes out the top vents on the windshield. When I select the vents or floor setting, it appears to work correctly, it is just the defrost which is the most important setting. I took it to the dealer yesterday, and they could not see anything obviously wrong although they charged me 150 dollars to look at it and wanted 900 more to remove the dash to start looking for the problem. Has anyone else ever experienced anything like this? I sure don't want to pay 900 bucks labor to go on a exploration mission, then pay more if they find the part that is broken.
Any help to avoid the stealership would be so much appreciated.
