Air Conditioning won't work

[MomVan]

Even though it's not hot out, I'm still getting my car ready for the summer heat. I tried my air conditioning and it won't work. I took it in because I thought it was the coolant that needed charging but that didn't work. It's still blowing hot air. What could be causing it not to work?

I would have thought the coolant too, if it's not that then I think you need to take it to a shop and have them look at it. It could be the air conditioner pump. I had to have my air conditioner pump changed out once and it was expensive.
