i purchased new the vehicle listed above semi automatic (gear and only 2 front windows automatic and central lock).

At morning time or after 3-4 hour stop time, always my A/C starts with big sound (like something start with too much force and jolt), but if after 1 or half hour working i do switch-off and restart , no sound.
please guide me what is the problem. and if possible give me any solution.

thank you,

it sounds like the a/c system maybe over full or it may have a compressor problem. Return to the dealer and have them test it!

Good morning,

The first thing I would check is the belt. If it is loose or the tensioner is not working correctly, it will make a squealing noise. As the belt heats up, it shrinks and the noise will disappear.

Beyond that, it could be the AC compressor itself. There may be an internal issue with the compressor such as low oil.

Does the AC system work as it should?

It would be great if you could upload a video of the noise for us to hear.
