The cluster is run almost entirely by the body control module. There is no power wire per se. Che k to make sure you are getting power to the bcm.
In this diagram, you can see the white/purple data wire comes from the pcm and goes thru the box you replaced on it's way to the bcm and cluster. Check that wies carefully.

I has a similar problem and I just took the battery out of my remote. I think there is a problem/ short in the remote. It's as if the button is being pressed when it is not. I will use my spare one in the mean time. It was driving me crazy becuase I was driving long distance at the time and when I removed the battery it stopped. I hope this works for you!

This should still be covered on your 4/50 warranty. It osunds like a bad keypad. Dealer can pull fault codes with scanner. Do you have ESP cintract also for more years and miles coverage?

Have you checked to see if the alternator is charging, and if there is something that is draining the battery overnight ?
