2002 Chevy Trailblazer electrical problem with passenger door

To all that made suggestions, thank you. We have solved the problem, it was a faulty swith on the passenger door console. The panel that has the electric window opener and power lock switch snaps out of the door, there is a module below it that takes three plug in connectors. One of them was bad. A quick trip to the local recycle yard for the switch module and $25 later all is well.
