Check the high and low pressures if okay, test the pressure switch and AC relay-compressor could be locked-up

You may have over charged the system, the A/C uses a measured amount of refregrant if over charged the high pressure switch will shut the system down, in your case there should be 2.4Lbs or 1.1kgs

Thank you both for your anwsers.
I only have a simple charging kit with a gauge. Should I try to release some freon? Or better bring it to car shop?
Thanks

Just found it works in the morning when it is cold. Does it give us any indication what part is wrong?

Thanks

If it is low there is a leak, did they fix that if not you will be back again with the same problem.
