Just bought my first dodge dakota 1998 ex-cab, 3.9 magnum.. I love it. 1 problem. Passanger floorboard is wet after short trips. It's not heatercore. I've read about drain tube, or putting silicone around the opening. Please help guys.. any ideas. It's not a leaking window, or splash up from rain. Thanks.

 

When I bought my Dakota, I had wet passenger carpet with water coming in from all of the following:
clogged fender drains causing overflow into fresh air intake (within the wiper cowl)
bad window seal on rear slider
holes drilled in back of cab that were covered by carpet
roof seam cap bolts missing or lose
body seam on back of cab leaking

so exercise due diligence and make sure you find em all
