Re: water building up on ps side floor board in 1996 jgc
Your water problem is caused by a cloged a/c drain. Under the hood on
the pass. side firewall you can see a small tube coming out of the
firewall (look towards the bottom). Take a coat hanger and try to clear
out the drain, this will solve the problem. You should get a good
amount of water come out.

The Evaporator box has a Drain tube, this is blocked and not letting the water drain off ,hence the build up of water in the box which will overflow into the passengers side .
The drain tube needs to be unblocked to let the water drain off.
this sounds like a build up of condensation (water) possibly in your ac/heat ducting or possibly in the plastic casings under the dash that house some of the heating and cooling components. cold ac components close to warm or hot heating components will lead to water build up this is why there should be a drain tube for the plastic housing under the dash board that leads to the outside of the vehicle. this drain tube may be clogged or may be disconnected and not draining to the outside but instead its allowing the water to fall into the area under your dash board. FYI you can sometimes see these drain tubes drip water on cars that use their air conditioner a lot, it looks like the car is leaking water from the bottom but it's just the water draining away from cool air conditioner lines on a hot day and draining properly to the outside of the car and not on the floor inside.
It sounds like condensed water from the air conditioner. Just like a glass with ice in it sweats, the cold part of an air conditioner sweats. That water needs to go somewhere. There is a drain on the bottom of the ductwork that comes out under the car, often toward the passenger side.
If the drain gets plugged, the A/C still sweats, but the water builds up inside the ductwork.
You can often clear the drain by blowing some air up the drain from the outside. (Don't use too much pressure!)
first check for a vacuum leak.if none,check air idle controle for not working or carbon build up that will sometimes make the pindel stick,also dodges have a valley pan bolted on under side of the intake those gaskets can leak and cause very wierd vacuum problems on the crank case. hope i was some help.
Your air conditioner water drain holes are blocked. Check the exit holes for water from the evaporator unit under the foot wells or dash unit. Through these holesor unblock these and the water will flow through to the outside
The drain from the a/c under the dash is plugged up and needs to be cleared. If you check from under the vehicle, u should be able to find the end of the drain tube on the passenger side, behind or near the front wheel. Carefully run a wire up the tube to dislodge the obstruction (goop build up). You can also use compressed air.
