Air condition not working properly

Welcome to 2CarPros.

First, this vehicle isn't offered in the US, so my technical information is extremely limited, but I will try to help.

The first thing I would recommend checking is the power supply to the compressor clutch. Check to make sure it is tight and corrosion free.

Next, take a look through this link. It explains the most common causes for an AC to not work. They are general, but may help.

Also, when it fails to work or stops working, I need you to pay attention to the AC compressor. Does it still continue to cycle on and off or does it just stop working?

If it continues working, the I would suggest checking what is called a blend air door actuator. This actuator is responsible for the air temp entering the vehicle. Here is a link that shows in general how one is replaced:

Let me know if any of this helps or if you have other questions.

Take care,
