I have tried disconnecting the battery to cancel all error codes and also checked the fuse and relay.

Someone has any idea of what might faulty or broken?

Thanks in advance

You've got a couple of things we need to do to try to narrow this down;

first, let's be sure it's related to your recent belt-change. All too often I've chased problems arising from recent work, only to discover they were entirely unrelated.

When you say the A/C does not work, Can we assume then that the control seems to function correctly, and the air is blowing correctly, it just doesn't get cold?
If yes - then we're diving back under the hood. Check to be sure that your belt is routed correctly, and then run the motor and look to be sure the belt is turning the compressor.
If yes - then we need to cycle the A/C button, and watch to see if the clutch on the front of the compressor engages or not.

If Yes - then does it STAY on? or does it kick, and then disengage?
If NO - check the electrical connection at the compressor. Check the fuses. Hit it with a test-light or meter. whatever you have that can diagnose so we know if it's a problem at the compressor, or elsewhere.

Hope this helps.
