Default 98 1500 5.2 passenger side floor wet??????

A/C condensate... when the seal between the firewall and the heater box deteriorates, condensate tracks along the bottom of the drain back inside.
The fix is a 90 elbow on the drain so the condensate drips away.

A blocked drain will also cause condensate to come out of the floor passenger vent.

Is the carpet wet on top near the vent, or is it just wet underneath on the floor?
At the bottom of the heater box where the drain is, put your finger in behind the carpet... is the insulation wet?

From what I can tell its just the bottom of the floor everything else is dry where exactly is the drain I need to put a 90 extension on id say that is the issue I will say that sometime in the morning when i firat take off for work it sound like there is water kinda running somewhere similar the sound of 2 liter bottle filled a quarter of the way up being turned upside down slowly if I were to describe it

The drain comes out the firewall below the a/c accumulator.

Check your cowl too, I had the same problem six months back. When I pulled the cowl covering off I found the drain plug had leaves and mud clogging it.

If you go that route, you just need to pull the wiper arms off and unscrew the plastic caps off to remove the black plastic cowl covering.

Ok I'm definately going to check that also because when I take off in the morning I can hear water sloshing around somewhere so it has to be pooling up somehow somewhere

The plug is a little rubber flap on the passenger side of the cowl, To pull the ams, use a screw driver or plyers to pull the pin back at the base of the arm and wiggle it off. It can be a pain. It can be easier with two people, one pulling back the pin and one wiggling the arm,

Thanks , I'm prpbably not going to be able to take the cowl off until this weekend but I did go by advanced and get a 90 degree grommet for the AC drain nipple seems to have helped but it also hasnt rained latly either something like this is so aggravating to me because it could be a number of things I did notice that the previous owner has siliconed the rear breaklight all to hell so apparently it is something that has happend for a while even when he had it lol
