99 Saturn SC2
Ever since I jumped my car the AC hasn't been working. When I press the AC button the green light will turn on but I don't notice any additional drag on the system like I normally would. I also notice that when I press the recirculate button the air doesn't become more powerful like it used to. Essentially nothing happens at all when I press these buttons.
Check your fuses.
There's one box near the floor, passenger side, and one under the hood. AC should be in there somewhere but could be another (e.g. maybe a fan fuse, although I suspect the compressor since you're not noticing engine load). There's also an AC relay under the dash, if no fuses are blown, check / swap out that relay.
Make sure you didn't knock any wires loose too, esp. since the car is so old, a fragile connection may have come loose or snapped.
There's always the possibility that another issue with the AC just popped up coincidentally but look for the easy electrical stuff first.
