Has anyone had this problem. I've got a leak under the dashboard that is soaking my floorboard. I can not find where it is leaking. My buddy and I are under the truck at this time trying to figure it out. Any recommendations would be appreciated. Uncle Randall

 

I think your air conditioning drain hose is clogged up and the air conditioning water is draining in the cab. Is there a puddle from the a/c under the truck? If not thats what it is. If thats what it is then you have to find the hose and unclog it

 

few ways.. if its like a rain leak. take out the carpet and seats and get inside and have someone with a hose start watering down the truck

 

I'd suggest that you start by removing the heater blower (after you remove the CC, and WS and Rad reservoirs). Clean out the debris, then get the garden hose in there to flush out the remainder. You can get one hand in there to clear out the corners.

Chances are, that's all it is, debris blocking the drain hole. If it smells like anti-freeze then it'd be your heater core. Hope that isn't your problem....

 

hah..hope its not your heater core im working on doing my 3rd in my 98, i can change it out in a half day if i dont get sidetracked lol, but whats it smell like, when does it happen-in the rain, going through water? do u have a body lift, and if so did u replace all body plugs?

 

It is probably the heater core. All you have to do is drain it.
