How do I troubleshoot a malfunctioning air conditioning system in my Kia ProCeed?

I've noticed that my Kia ProCeed's air conditioning system is not working as well as it used to. What are some potential causes and steps I can take to fix it?

First, check the air conditioning belt and make sure it is not worn or slipping. This could be causing a lack of power to the system. If that's not the issue, then it might be a clogged air filter. Try replacing it and see if that improves the air flow.

Another common issue with air conditioning systems is low refrigerant levels. You can contact a mechanic to fill it up for you or you can do it yourself with a DIY kit from a local auto parts store.

If none of the above solutions work, it could be a more serious issue such as a faulty compressor or evaporator. It's best to take your Kia ProCeed to a certified mechanic for a diagnostic and repair.
