My a/c stopped normal cooling, it cools only in the mornings or evenings and that has stopped for the worse. Whenever I put it on the engine rev and temp increase and it does not cool.

This sounds like the compressor has gone out or the system is low on charge or a fuse is bad, these videos and guides can help us fix the problem with diagrams below to show you how on your car. I have included (below) the air conditioner wiring diagrams as well so you can see how the system works.
