Ill have to use the key to initiate the window roll down t o unlock it. Then it will start to work again a few times then surprise, I can get in again. At one point when the battery was on its way down the locks kept initiating spontaneously so I just disconnected the battery, charged it up and it was back to normal.

I put a AGM battery a week later it was dead, charged it up four days later dead- they said it was a bad battery. Got a new one put it on a trickle charger. I just tested it this morning and the locks worked just fine but didnt work 2 days ago after driving it. I am going to disconnect the master switch this weekend and take a look at my harness and do as SouthArk370 suggests. I am also looking at just buying a master switch of of ebay and swapping it out, not sure yet. I will update once I take a look.
