I'm assuming this H3 has a sunroof. I'll bet you have a plugged drain tube. Open your s/r and look at both front corners to see if there's a visible blockage(dirt,pine needles,etc) that can be easily cleared. If you don't see anything then it's probably dirt or some other debris stuck somewhere down the tubes. You'll need to use some compressed air and a nozzle to blast it out from that end.
