My 93 Legend has been a wonderful car to own; no real problems since the day I bought it 10 years ago.

If there is one complaint, it is that the A/C is weak. This isn't something recent; this was the case when new. I've had the system checked, way back under warranty, but no problems. Is there anything one can do to improve this? I know people do all kinds of wonderful things to their cars to make them run better, but I've never heard of an aftermarket A/C replacement!

Thanks!
