AC intermittent

On My 2003 Trailblazer EXT. 1st the air was like cutting in and out while Driving, then a 2 days ago it wouldn't start when you started but on down the road it would kick in... now it doesn't want to come on, Twice now it I have lifted the hood and wiggled the wire on the switch on the exaporater and it has seemed to start working and once it's works it works good and doesn't seem to quit..

Anyone have any idea's??

I had the same issues a few years back. You need to get the switch on the evaporator replaced. That fixed the issue. Mine was under warranty so not sure how much it will cost if you need to pay for it.

If it's not a pressure switch, it sounds like a bad fan clutch.
