What are the reasons why the X-Trail's AC only blows air but doesn't cool?

[McMariana]

Below are the reasons why the X-Trail's AC only blows air but doesn't cool: Incorrect mode: If the fan starts but the main unit doesn't, check whether the remote control is set to cooling mode, and adjust it to cooling if necessary. Insufficient refrigerant: If both the fan and main unit start, check whether the refrigerant is effective. If not, add refrigerant, but before doing so, check for any refrigerant leaks and repair them if found. Compressor malfunction: Check whether the compressor starts. If not, seek professional help. Loose compressor belt: If the AC compressor drive belt is too loose, tighten it appropriately. If the belt can't be turned by hand, it's too tight and should be loosened slightly. Of course, if tightening doesn't work or the belt shows cracks, aging, or other damage, replace it with a new one.
