SOURCE: air conditioner leaks (drains)into the front passenger seat floor mat

I had the same problem. Drilled a hole in the round plastic extension beneath the glove box, behind the carpet. Now run a coat hanger through it, followed by alot of compressed air. It may take several times, debri from above may be continuosly replugging drain. when you are done, clean thoroughly, and patch with hot melt glue. Good luck.

Hey there Dave,

Had the same thing happen to my Wrangler about three years ago.
It was the weep hole too.

I drained the coolant, dried the weep hole and plugged it with a small amount of that solid epoxy they market to fix holes in gas tanks. I refilled the radiator and the plug held.

It's still holding.
Just an alternative option

SOURCE: 2003 Jeep Cherokee Leaks Water on Passenger Side

Just had ours fixed, look on engine side of firewall, if the outlet pipe in passenger well is a 3/4 inch long pipe projecting forward into engine bay with no tubing leading down towards the ground, the problem is water comes out trickles back with pressure in engine bay to foam seal under the pipe and enters footwell inside car.
Take a piece of rubber tubing and hose clamp it on and direct it down towards ground in engine bay and the problem will be solved!
We have gone from soaking carpet to no leak at all with this simple fix.

SOURCE: 1998 jeep grans cherokee leaking water in the

Hi Vichall,

The first step is to locate the leak and identify the source.

Pull the rug back. Dry the area. This will help locate new moisture.

  • Is the water clear? Does it smell sweet?
  • Does it only leak with the engine running? After Turned off? All the time?
  • Does it only leak with the heater on? A/C on?
  • Is your coolant level down?
  • Is their a time of day it happens more? (Early morning)
Comment back with your findings. We can take it from there

Best regards
Mike

SOURCE: 2002 Jeep Grand Cherokee fluid leak

That is the area the air conditioner vent drains. There aren't a lot of fluids possible - coolant, power steering fluid and transmission fluid are the only ones that would be in that position unless your windshield washer fluid leaks from the tubing. Brake fluid would be closer to the wheels. If the air conditioner runs at all it removes moisture from the passenger compartment and drains near the passenger side firewall. All the other fluids would hae a definite smell.

Cant find ac drain tube


Pull the carpet down in the passengers foot well and locate the evaporator drain in the housing.

Drill a 1/4 inch hole in the center of the drain tube housing as shown. Clear the drain tube with a wire or suitable tool by inserting it through the hole and into the drain tube.

Insert plug, P/N5255217 into the 1/4 inch hole drilled previously. Verify that the drain is clear by operating the system in the A/C mode and observing that water is draining.

Hope this helps.

Our 1997 TSI Grand Cherokee air conditioner is leaking in the passenger side. How do we fix it?


You preliminary diagnostic about leak is hafl correct, but this is of a clogged A/C drain hose. It's a very common thing to happen. Here some details:

If your vehicle has an A/C drain hose, it will be located on the engine side of the firewall, below where the two A/C lines go through the firewall.


NO: 24-18-94
GROUP: Heating & A/C
DATE: Nov. 18, 1994
SUBJECT: Condensate Drain Tube Eliminated


MODELS:
1994-1995 (AN) Dakota
1993-1995 (XJ) Cherokee


DISCUSSION: The above vehicles no longer use an air conditioner condensate drain tube. Cherokee's built after September 3, 1993 (MDH 09-03-xx) and Dakota's built after June 1, 1994 (MDH 06-01-xx) no longer need the condensate drain tube. Do not install in the field or submit a shortage and error request.

Somewhere just below the Suction and Liquid Lines you will see a small black hose coming through the firewall and pointing down. This is the A/C drain hose. Take a piece of wire and snake out the hose. This will clear the blockage and allow the water to drain out.

You may have to remove the drain hose completely. If so, it just pulls right out and you can slip it back on easily enough.

Water on the floor


I've ran into this problem before with another jeep. What happens is the condensation drain line from the evaporator housing gets plugged with the material that insulates the housing and the water can't drain and seeps through the seems and drips on the passenger side floor. Chrysler did at one time sale a plug kit for this. What you would do is drill a 1/4" hole in the side of the housing on the left hand side near the bottom and put a stiff piece of wire in it to unplug the drain line and then plug the hole with the plug kit from chrysler. just when your drilling the hole make sure you don't drill into the evaporator core or your freeon will leak out as well. I'm not exactly sure how far from the bottom to drill the hole if I remember right it is 2 inches just about center. Chrysler did have a service bulletin on this you may want to ask them when you see bout the plug kit.

AC leaks condesation in my 1996 jeep GC


keeper of fire here is mostly right...however, on my 96 grand cherokee with the 5.3 liter V8, there is a slight design flaw...the evaporator tube is actually IN the framing...
this baffled me for a time, until a local jeep mechanic told me that this was regular in a jeep zj, and that all i had to do was pull back the carpet on the psg side and drill (yes drill) a hole into the plastic so you can stick the wire in, or an air hose and unclog your tube from there...then you silicone it back up and tada!! be sure however that before you drill willy nilly that you are actually drilling in the right spot, this can kinda be found by following what bit of hose is visable and seeing where it disapears into the floor...and its a little black plastic circle that you will drill into...hope this helps!

The passaqnger floorboard is getting wet with condisation from ac


also you should put glue silicone sealant around that black plastic piece you drilled. The glue shoud be between that piece and the metal sheet. I had this same problem and I solved it that way, it has worked fine ever since.
