ok in my other post relay has been lacking to turn on how do you determine that the a/c fuse is blown? would it be dark around the prongs?

Take the fuse out and look at it. If its blown you'll see the filament burnt in the middle. Also, you could use a test light or a multimeter to check it.

Usually when the a/c does not come on that means it too low on freon.
