How do I troubleshoot a malfunctioning AC in my Kia Rio?

My Kia Rio's AC has suddenly stopped working and I'm not sure what the problem is. I've checked the refrigerant levels and they seem to be fine. What other things should I check for and how can I fix this issue?

First, you should check to see if the AC compressor is running. If it's not, you may need to replace it. It's also possible that there is a problem with the electrical system, so you may want to have a professional inspect it.

Another common issue is a clogged cabin air filter. This can cause the AC to not blow cold air or have weak airflow. Check and replace the filter if necessary.

If you've recently added refrigerant and noticed a leak, it's likely that there is a bigger problem with the AC system. You may need to have it inspected by a mechanic to identify and fix the source of the leak.
