2003 h2 hummer right rear door sensor switch must be sticking dash reading says it ajar I open and shut that door and all others few times but no luck

You can try spraying WD-40 directly into the striker section of the latch and open and close the door several times to try and free the switch up, but even if it starts to work again, it is just a temporary repair. You will need to look to getting the latch replaced soon.

Water leaking from roof area of 2004 H2 Hummer ,lights ,door and sunroof

this was actually a common problem with the early models. you should take it back to the dealership where a technician will perfrom a "tsb" on the drain channels that run through the "A" pillar. they got pinched during assembly. best case it might be clogged with dirt in which case you can blow through these channels yourself with compressed air. they are located in the front corners of the sunroof channel while open. good luck.
