Aircon does not work

[delz0r]

Hi all. My aircon does not work. My mechanic has tried to fix it but no matter what it will not blow cold air. He has tried:

• Re-gassed
• Sealed
• Pressure tested
• Checked power to the pump
• Scanned for faults - none

All pressure and temperature readings are as they should be but it will still not work.

Has anyone encountered this and fixed it? It’s driving me crazy now with the summer temps.

Air compressor could be bad. Does it engage?

Take it to a different mechanic. AC is normally not very difficult to diagnose

If its out of gas then the main cooling fan will go on full speed on then off & it will keep doing this.

Otherwise I would look to see if compressor engaged.

Start with the most obvious - is the scroll wheel for air temp on red rather than blue?
