Report: Heater Stuck on Hottest Setting Due to Broken Heater Blend Door
Ford Explorer Problem
Average Mileage: 103,348 mi (8,700 mi - 275,000 mi)
A failed heater blend door or actuator can cause the temperature control for the HVAC system to stop working. A clicking sound from the dash area would commonly indicate an actuator fault. If the heater gets stuck on the hottest setting, the heater blend door may be broken requiring replacement of the heater box to repair the issue.

Blend Door Actuator AKA "Click of Death"
It began simple enough with a clicking sound coming from the A/C. First the actuator controlling the vent settings quit, leaving defrost as the only setting that worked. Then the clicking got louder and then the heater quit in December. After much searching on the internet, we found a way to set the actuator on hot. This problem seems amazingly common and has been for years. Why hasn't Ford fixed this?

Blend door broken, Had to replace it. Shaft was broken where it attaches to actuator control.
When switched to hot it would sound like a timex watch. One day it stopped and would only blow cold. i called Ford and some local repair shops and no one could give me an answer wanted to put it on their machine to charge me $95.00 so i called Autozone the man there told me I needed a repair kit for the blend door $16.00. Now the problem is there was no instructions on how to get to this box. I did find out that the whole dash has to come out. I need some instructions from that point.

THE TEMPERATURE CONTROL KNOB WOULD BE STUCK IN EITHER THE HOT OR COLD POSITION
Heater control ticks and wont change on demand. IT acts as if a vacuum line is loose or broken. If you turn the fan on wide open and keep moving the control to change from floor to vents. Eventually it will slamm and change. I'M NOT SURE HOW TO FIX. CAN YOU HELP?

My 2005 Explorer has had a thumping noise in the dashboard for over a year whenever I turned the temperature knob either up or down. Now, my heater seems to be stuck on extremely hot, even when the air conditioner is turned on. This is problem is even more difficult to live with since none of my windows will go down. I am also experiencing a thumping noise in the rear driver's side of my Explorer.
