Hmm, first time here. Hey people.

So after searching I finally got myself a 3rd gen 2.0 si prelude. At first I wanted an integra but finally decided on a prelude. It's such an amazing car! Well, for 137 HP it really flies!

Anyway, so everything is fine but for some reason when I turn on the AC, sometimes this litle red light on the buttom would come on and the AC would be disabled (compression light?). Sometimes pushing it off and back on works, but recently that failed, too. Could someone please give me some possible explainations on the reason and how to fix it?

Thanks for your time!
