I've cleaned the windshield with alchohol...Windex...3 times....installed new blades...and the wipers still skip across the windshield...even when it's completely wet and it's been raining. WHY??? HELP!!!

Probably bent wiper arms. Check to see if the arms are flat/parallel in relation to the windshield. If they are bent in one direction the wipers will chatter because it changes the pitch of the wiper blade.
Do they start skipping above 100mph (just kidding)!
Weak wiper arm springs will also allow the blades to skip because there is not enough pressure on the blades to keep them "seated" on the windshield. Also wiper blades that are too long will cause skipping (I install new blades that are 2"shorter than originals to stop the skipping)
