Replacing Ford Max Air Door – AC Not Cool Enough

Air door
A Ford Explorer that has a full charge of refrigerant and is cooling, but is not quite cool enough may have a broken fresh air door. The fresh air door is additionally referred to as a recirculate door, max air door or main air inlet door. The function of the door is to let fresh air in. Alternatively, to recirculate the inside air. When the air conditioning control is set to the max position, the new air door seals from the outside air to recirculate the air inside the passenger compartment. When the air is recirculated, cooler air temperatures can be obtained because the air is cooler in the first place, compared to the outside air.

Not Simply Ford. Any vehicle having a broken recirculation door or actuator that moves this door may have this issue. However a broken blend door is a common problem with the Ford Explorer. This is often checked easily. First, listen for increased ventilation when changing the the AC to max. If the air doesn’t sound louder in the max position, there’s a good chance the recirculate door is broken. Next open the glove box and look for movement of the recirculate door when switching from normal to max air.

Dash Removal. If the door is broken, dash removal is required to access and change the door assembly. Book time pays 6.9 hours not including take a look at time and evacuation and recharging. This job can be done by a skilled technician within 45 minutes, with no reason to evacuate and recharge the AC system. The dash is not completely removed, just unbolted and swung to rest on the passenger seat to allow replacement and removal from the main air inlet door assembly.

Take away the Console. Eliminate the center console upper trim (one 7mm screw), unplugging the power outlet. There are 2 10mm bolts securing the front in the console for the floorboard. Move the seats forward, from the back seat area remove two 10mm bolts from the sides of the console. Now the console is loose, put it to the side.

Unbolting the Dash. After disconnecting battery, take away the trim panels from the sides from the dash and also the defrost trim through the top. The two main bolts on either side as well as 2 on the top. Unbolt the steering coupler nearby the driver’s floorboard. There is certainly one hidden 10mm bolt that is accessed from the outside.

Sneaking it all out. No reason to take away the cowl and wipers trim. Gently pry the cowl trim up leaving it propped up about an inch as well as a half to allow accessibility bolt. Have a magnet pick-up tool handy if your bolt falls out from the socket. Unbolt the wiring harness around the right side and unplug the antenna.

Swing It. Slowly swing the dash out with care not to put excessive force around the wiring. Once the dash is retracted, take away the 8mm screws from your metal support bracket and the top of the the entrance assembly. The two main 8mm screws that can not be accessed, pull around the fresh air door assembly break it from the evaporator case. Now take away the 8mm screws and remaining plastic, making certain no plastic pieces fall under the blower fan.

Right Stuff. Rather than re-utilizing the two 8mm screws on the difficult to access attaching points nearby the firewall, apply Right Stuff sealant or perhaps a similar substance to secure the new air door assembly. Then re-attach the remaining 8mm screws that may be accessed. Much time is saved, by using the right stuff securing method. Now re-install the dash and console plus an eight hour job is done in approximately 45 minutes!
