On the passenger side handle on the pillar water leaks from there. Does anyone know where this is coming from? Its an 03 H2.

 

Hi it could be the right corner clearance light if its dipping down on the handle. If you remove the light their is a rubber gommet under it, for the wires to go inside the truck or it maybe one of 3 middle the front clearance lights.

 

I agree with twr1
