Question about 1997 Jeep Grand Cherokee
I believe that this occurs only when the A/C is on. It absolutely drenches the passenger side with standing water. I located a possible fix posted below that does not look easy. I was hoping that someone could confirm that this is a solution, or suggest a better one before I tear my entire dash apart to get to it.
The evaporator for the AC system is located half in the engine compartment and half in the firewall on the passenger side. Inside this drain box is a Styrofoam liner that is supposed to prevent condensation on the outside of this plastic box and dripping water on the passenger's legs. Unfortunately this liner is very thin and flimsy and falls apart over time which not only plugs up the drain hole but can also become lodged in the cold air vents in the dash...you would actually see white Styrofoam in the vent as if someone put a piece of a Styrofoam cup in the vent. The previous writer is correct in that there isn't a hose leading down allowing condensate H2O to drip out on the ground but rather its a closed system which puts the H2O into the frame rail (unibody design) so it is impossible to blow out the hose as in lots of other designs. The fix is to completely disassemble the dash in order to remove the box and clean everything to replace this Styrofoam.A mechanic will charge significantly over a thousand dollars in labor to replace this $40 part and its a job that is almost impossible for ado it yourselfer due to the complexity of dis assembly of the dash.There may be a way to drill a small hole in the box from the engine compartment in order to blow out the system and to install an alternate drain hose.....if anyone knows about this please let me know !!!
Yes but drill the hole in the passenger compartment on the bottom of the box where it slopes down to the drain. Blow out the hole with compressed air and then plug the hole with a rubber plug or silicon. If you use silicon let it dry for a least 2 hours before running your air conditioner. Now if it happens again you have an access hole to clean out the drain. You want to drill the hole toward the firewall like you were drilling toward the drainhole.

There is an easier way. On the inside of the vehicle, passenger side under the dash against the firewall, you'll see the ac/heater housing. Pull the carpet back a little to expose the very bottom against the firewall. You'll see the backside of the drain. Approximate the center about one inch up from the bottom.
Have your compressed air ready, water may come out.
See if the water is draining from the framerail when finished.
