Water leaking into my cab...?

[The BEATTIE]

Hey guys, I have water coming into the cab of my truck. So far I've sealed the 3rd brake light, around the top of the trim of the rear sliding window and the passenger quater window. I can't figure out were it's coming from so any suggestions as to where to look would be greatly appreciated

i had a similar problem. water would leak inside and soak the underside of the passenger rug. it would flow in different directions. i was concerned about it causing electrical problems . i spent a full day looking for the leak. i found that the heater/ac blower housing was filled with water. you need to remove the blower fan from inside the engine compartment passenger side. once removed stick your hand inside.the bottom area should be dry if not the water is leaking from a fresh air duct right above the fan.you can stick your hand up into the cover. this slotted cover is placed over the hole for fresh air intake held in place with some type of sealant which dries out over time causing any rainwater to travel thru the cracks into housing and other places. if you determine that this is the problem you have to remove your wiper blade assembly then stick your arm from the drivers side to passenger side under the cowl, clean area around duct and apply a sealant where they seal. check it out.
