The most common reasons a 2014 BMW 640i xDrive Gran Coupe AC isn't working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.

Refrigerant Leak: A refrigerant leak can occur due to damaged hoses, seals, or connections, resulting in decreased cooling efficiency in the air conditioning system.
Climate Control Electrical Issue: A faulty climate control module or a short circuit in the wiring can disrupt the electrical signals needed for proper operation of the climate control system.
AC Compressor: A faulty AC compressor may be due to a lack of lubrication, electrical issues, or internal mechanical failure, resulting in inadequate cooling performance.

Nissan Rogue AC compressor failure causing hot air from air conditioner

Some Nissan Rogue owners report experiencing issues with their AC compressor, leading to hot air blowing from the air conditioner. These problems often stem from a faulty compressor that can cause the air conditioning system to malfunction, resulting in hot air instead of cool air from the vents. Common signs of AC compressor failure include unusual noises and a noticeable lack of cooling. If the compressor fails, it compromises the entire air conditioning system's functionality, significantly impacting the vehicle's cooling efficiency.

Updated Pressure Cycling Switch Available to Fix Frozen AC Evaporator

The AC evaporator may freeze after extended use of the air conditioner. The output may feel low due to the restricted evaporator. Once the ice buildup melts, the AC operates normally. A revised low pressure cycling switch is available which may fix this concern.
