So my ac isn’t working and the shop couldn’t fix it. It charged and will sometimes blow a little cool air. The compressor doesn’t move out the fans. The fuses are I heard the box on the battery wires go bad so sometimes replacing that fixes it. The car doesn’t overheat

I have a 2004 Jetta and my ac doesn’t work. It’s been charged and I took it to a shop and they couldn’t figure it out. If it’s not too hot outside it will blow a little cool. But when it’s super hot it just blows hot. Any ideas?

I've looked through post after post for a couple weeks now. So this is why I decided to post. I have a 2000 Jetta. I bought it 2 years ago, about a month after I took it to a garage to change the tires and let them do a few other basic things, new belt, new battery, pour in some washer fluid...
