What to do when your a / C is not working in your Volvo?
A quick way to confirm compressor clutch failure is to manually turn the AC on and off. Once the AC clutch obviously disengages itself and begins blowing warm air, turn off the AC with the button on the center console. Give the clutch a few minutes to cool down before turning the AC back on.
Why is my Volvo air conditioner not cooling?
If it is cooler then it will cause the CCM to switch off compressor too much and at too high a temp causing poor cooling from A/C. The probe can get blockaged from dirt and debris but this usually causes the evaporator to freeze and stop airflow with no compressor cycling.
Why does my car AC blow cold air then blow warm air?
But that cold air turns warm fairly soon after because the high side pressures build to the point that the high pressure switch shuts off the compressor clutch. Once pressures equalize, the high pressure switch allows the compressor to start up again. The cycle repeats over and over, providing a short period of cold air, followed by warm air.
What to do if your Volvo S40 has a leak?
When the air conditioner in your 2005 Volvo S40 starts blowing hot air, you likely have a freon leak.

Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant.
