What are the common problems in Ford Mondeo's air conditioning system?

I've been experiencing trouble with my Ford Mondeo's air conditioning system. It sometimes blows warm air or stops working altogether. What could be the cause of this and what steps should I take to fix it?

This could be due to a leak in the system, clogged air filters, or a malfunctioning compressor. It's best to take your car to a certified mechanic to diagnose and fix the issue as it requires specialized equipment and knowledge.

Before taking your car to the mechanic, you can try cleaning or replacing the air filters. A clogged air filter can cause the air conditioning system to not work properly. Additionally, check for any visible leaks in the system and have them repaired if necessary.
