well I've tried everything I can think of. I have a leak in my truck that seems to get the carpet sopping wet on the passenger side front. however, there's no Trace of the carpet being wet trailing in from the rear or from the front or from the hump. It's just as if the puddle appears in the middle of the front passenger foot area. now, I've been trying different things and am almost out of options. firstly, I've sorta ruled out the heater core since there is no coolant odor or anything but water on the towels. I've re-sealed the windshield, rear window seals, I've used waterproof tape to tape up the vent windows, front vents under the windshield (what are these for anyway?), I've tried clearing the a/c drain with a garden hose and it seems to drain out when I do this and when I run the a/c. plus even with all that hose pressure it doesn't leak into passenger compartment. is there a way for water to enter from under the cab somehow? I just did use the tape to tape the door shut because I installed a new seal around the passenger cab door opening on the body. but, the driver-side seal is the one that should leak. it has rips in it I several places but no water on the driver-side floor. upon taping the passenger door shut i found it to still leak somehow. really stumped.
