PROBLEM SOLVED! I got a test light and tested the two blue wires like dc98cam suggested and what i found was the wires were barley lighting the test light and while the engine was on it was flickering, but barely noticeable. and the door lock wires were testing fine. previously i bought a new tail light relay so after looking at the diagram i switched the new tail light relay with the power relay that runs the windows. problem fixed, i suppose the original power relay was bad. the tail lights still work but it may be because i jiggled the relay while switching. so if my tail lights go out i know to buy a new relay. so the conclusion is if all your windows stop working all of a sudden but your door locks work, and you test the blue power wires on the harness and they show little or no current, more than likely its the relay and you can test this for free by switching relays with one of the other two assuming they are good as well.
thanks for your help dc98cam, as well as your help with my tail light problem about a month ago.
