Koleos AC not blowing cold air

I had a similar issue last year on my Koleos. Does the AC make any strange noises when you turn it on? Mine was completely silent, and it turned out to be a refrigerant leak.

Thanks! No, there are absolutely no noises when I turn it on. If it's a refrigerant leak, is that hard to diagnose or fix? How did you resolve your issue?

If there's no noise, a leak is likely. You need a workshop to test the system pressure and coolant level. They'll find the leak with dye, but fixing it might be expensive.

Thanks for confirming my suspicions! I'll book a workshop to check for leaks. The estimated repair cost I received was around 1000€. I appreciate your help!
