I went to Halfords UK, for air con refill. After the refill, it blows somewhat warm air.
Also every few seconds, there's a vibration and something that sounds like something releasing near the engine, it didn't make that noise and didn't vibrate every couple of second before we visited Halfords.
Anyone know if they broke anything and are they able to fix it, or if I take it to Nissan, should I give them the bill to pay for breaking my car?
Sorry, I'm not a car guy
