BMW 7 Series front air conditioning is not blowing air while the rear is abnormal. The following are the reasons and solutions for the front air conditioning of the BMW 7 Series not blowing air: Reasons why the front air conditioning of the BMW 7 Series is not blowing air: The BMW 7 Series air conditioning may be cold on one side and hot on the other due to insufficient refrigerant, a faulty compressor on one side, or a malfunctioning warm water valve. The car air conditioning system is designed to cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The BMW 7 Series is BMW's top luxury sedan series, featuring a 4-door sedan body style and front-engine, rear-wheel-drive configuration. In terms of dimensions, the BMW 7 Series measures 5212mm in length, 1902mm in width, and 1478mm in height, with a wheelbase of 3210mm. Exterior-wise, the BMW 7 Series features a front grille and headlight assembly, with the iconic double-kidney grille being 40% larger than the previous model. Solution: Check the air conditioning control panel to see if any plugs are not making good contact.
I've been driving for many years and have fixed quite a few issues like this. If the front air conditioning in a BMW isn't blowing air while the rear is working fine, it's most likely due to a stuck air door actuator. This component controls airflow distribution—if the front air door is stuck, no air will come out. My buddy's 7 Series had this exact problem: the front was hot as a sauna with the AC on, while the rear stayed cool. Turned out the actuator motor was either burnt out or jammed from too much dust buildup. A faulty blower motor resistor could also be the culprit, affecting only the front fan speed. Don't mess around—first, check if the AC mode is accidentally set to defrost, and adjust the vent direction back to 'panel.' A clogged cabin air filter can also restrict airflow, especially at the front intake—replacing it might solve simpler cases. If all else fails, get a professional diagnosis. If it's a control module software glitch, you can't afford to delay. Driving without cool air in hot weather can be distracting and lead to accidents, so address it promptly.
