Change of seasons typically reveals issues with a automobile that may in any other case go unnoticed. If in case you have a Jeep Grand Cherokee or a Ford Explorer that has an outdoor air leak behind the glove field, then you’ll have a damaged contemporary air door (AKA Recirculate Door or Max Door). The contemporary air door is used to both recirculate air within the passenger compartment or permit contemporary air to enter the HVAC (Heating Air flow & Air Conditioning) system. Surprisingly the Explorer and the Grand Cherokee share a typical flaw within the heating and AC system. The contemporary air doorways are weak plastic that many instances below the stress of the management actuator can break. When it is chilly exterior this downside makes itself very obvious. In hotter climates within the summertime, a damaged contemporary air door drastically reduces the air con’s effectivity.
Checking it is simple by working the contemporary air door and listening for elevated airflow. When the local weather management setting is moved to max, the sound of the air blowing by the vents must be louder as a result of the contemporary air door is sealing off the surface air, forcing the within air to recirculate. If the sound just isn’t louder, you possibly can open the glove field door and look behind it for the operation of the door when switching the setting from regular to max. If the door just isn’t visibly shifting, it’s seemingly that it has damaged. The door typically may even fall to the underside of the case, positioned proper above the blower. It is probably not in sight, typically you possibly can stick your fingers by the plastic grate and really feel the door laying unfastened on the underside.
Substitute of the door just isn’t a do it your self job. The sprint must be swung out and the HVAC case eliminated on Grand Cherokees. On Ford Explorers the job might be performed with out the removing of the case, however the meeting should be changed. Clearly if the case must be eliminated, the refrigerant should be recovered, which requires an ac machine. So if you’re mechanically inclined the one which may be performed at residence could be the Explorer, in fact this relies on your mechanical potential. Even if you’re not going to do that job your self, this data can be utilized to assist clarify to the restore store what the issue is. By offering extra data to guide the technician to the issue space, prognosis time might be lowered.
