What should I do when my BMW X1's AC stops blowing cold air?

My BMW X1's AC was working fine, but suddenly it stopped blowing cold air. The air is just slightly cool, but definitely not cold. What could be the issue and how can I fix it?

First, check your car's refrigerant levels as low levels can cause the AC to stop blowing cold air. If the levels are low, you will need to refill the refrigerant.

Another possible issue could be a clogged air filter. A dirty air filter can prevent proper air flow, making the AC less effective. Make sure to clean or replace the air filter if necessary.

It could also be a problem with the compressor or a leak in the AC system. In these cases, it's best to take your car to a mechanic for a professional diagnosis and repair.
