Upon starting the vehicle, I turned the climate control to the defrost setting. After 5 minutes, no air was blowing to the windshield, only from the dash vents. No floor air, no defroster air, only dash vent air. Temperature adjusted from warm to cold just fine, however. I called the dealership that I purchased the vehicle from, was told to bring the truck in for a diagnosis at a fee to provide an estimate. I called a second dealership, was told by the service manager that by my description, the "recirc" door and "mode 1" door needed replacement. The "mode 2" door might also need replacement, but that my "blend" door is working. The estimated cost to repair would be around $1300 to get my defroster functioning again. I asked if this was a common issue, he said it was very common. I asked if there was a recall on this issue, he replied that there were no recalls for comfort features, that he was aware of. I would think that the defroster was a safety issue for visibility while driving.

Ac defrost heater air recirculation door breaks off it plastic axle, drops into and blocks the air intake into the blower motor. Thus resulting in no airflow thru the heat vent ac defrost system. Causing visibility problems since the defrost system will not get the proper airflow to work.
