Windows not working at all none of them just making a clicking noise that’s it. My floor is wet on passenger side floor and when it rained it did used to have tiny drops of water from sun roof in my 2003 hummer h2 please help.... I did replace driver control switches for windows and checked relays still nothing.

 

First thing to do is clear the leak problem to keep water out.

The moisture could have caused a number of problems. Short circuits etc. Check back after solving water issues.

 

The windows control is complex, the Drivers Door Module (DDM) Passenger Door Module (PDM) Left Rear Window Switch and Right Rear Window Switch all link via the BCU.

A few extra details would help :-

1. Were the windows working OK prior to water ingress?
   
2. Was the fault the same after replacing the DDM?
   
3. Are the mirrors, heater and memory switches working?
   
4. Has anything else been changed or modified recently?
   

Anyway, one common point is Ground 203 (G203) see graphics below. Perhaps a large "rush" of current causes communications to die, which may produce the "click" as the window relay turns off.





I'd be tempted to check all the ground points i.e. G203, G302 & G306

Good luck and please update the forum with your progress
