Jeep Grand Cherokee Water Leaks
Its been raining here so now I seems to have joined the Wet Floor Club. My drivers side carpet is soaked. I sucked water out twice now with my shop vac but the pad is still wet. This seems like a common Jeep problem from what I read online. Is there a comprehensive list of potential leak sites for the GC to check. I do not have a sun roof; that eliminates one huge issue. Any help and/or suggestions welcomed.

2004 Jeep Grand Cherokee Limited
Here's what the dealer told me when my passenger floor became soaked following a rainstorm:
Performed water test. Found leak at right cowl area. Repaired passenger side leak at right cowl area. Total Charge: $204.00
About a week later, we had a violent rainstorm. Passenger side floor soaked again. Returned to dealer. This time they sealed door moisture barrier. No Charge. Another week...another rainstorm..another soaked floor. Returned to dealer a third time. They spotted a leak in cowl area. Resealed front cowl. No Charge.
In Dec, 2009, after a break in the weather, I drove my car down my block and water started to come out of both passenger and drive pillars, my DVD player and the remote area above the mirror. I brought it to the dealer and after 2 days diagnosed it to be crimped drain lines and claims they fixed it.
Yesterday, after a major rain storm, I once again drove my Jeep down the block and again water came out of the driver side pillar, DVD player and now the back hatch area on the driver's side. I brought it in today and they have advised me it is leaking everywhere and they are trying to diagnosis the problem.
Has anyone experienced this type of issue?
Confused from Arkansas driver!
Don't know if this is your problem, but you never know. I had a 94 olds 98. I got water on my floor boards in the front and back. I fought this for months. What I discovered was this: The water coming off the windshield, most of it gets directed down into that plastic cowling at the base of the windshield. .From here it is channeled to both sides of the fenders to where it drops down inside the fenders to the ground underneath the vehicle. In my case the opening in the bottom of the fenders were plugged with dirt, leaves and pine cones. Once I cleaned this out the best I could I stuck my hose nozzle down there and blasted out with water. You could see the water then pour out the bottom of the car. If you open your driver and passenger doors look down inside the fender well below the bottom hinge. This is where I'm referring to. Once I cleaned these drains out and hosed them out every 3 or 4 months I never had a problem again. Hope this helps .
Just for testing, I ran an older Jeep Overland and Honda through the same car wash not a drop of water.
Thus far the dealer has not been able to duplicate the problem or find a potential cause. Naturally...
Been through this problem before with my first Jeep (1990?) and the dealer never found the cause. The difference was both sides leaked from under the dash, but only when it rained and never in a car wash. :P
I ended up taking clear gasket sealer (silicone) and a small straight screwdriver for this job. first I stuck the screwdriver between the gasket and the windshield frame,pulling back slightly not to tear the gasket. There was muck and dubree between the gap,so I cleaned it out first. A good paper towel will do the job ! Slide the screwdriver across the top of the windshield underneath the gasket in one hand and the paper towel pinching the gasket down as far as possible into the gap. Remember not to force anything,you don't have to.
Now, after you have cleaned the underside of the gasket, let it dry a few minutes to evaporate any moisture left from the towel. Now it's time to apply the silicone.
With the screwdriver,starting at either side of the windshield start it under the gasket,pulling it back enough to keep a steady stream of silicone and move across the windshield at your own pace ,keeping the silicone under the gasket and a solid bead of sealer . Make sure there are no gaps in the silicone, then let it dry over night, you should have no more leaks. This can be done to any windshield with a gasket that can be pulled back and cleaned without tearing the gasket.
I hope this helps someone, it solved my problems !
1) When it's parked
2) Front end facing uphill (it won't do it if it's facing downhill)
3) When it Rains.
4) Passenger side only.
The amount of water is only limited by what the passenger floor will hold! It started doing it in 2010 after no problems in the past.
The only thing I can think of is that there is a tube leading to the firewall and something rusted through. Anyone know what to do?
1) Sunroof ECU settings. The sunroof would accidently "close" at the incorrect level -- too low by up to a quarter inch. This can be solved by manually adjusting each time when you close it or paying to have someone reset the sunroof setings.
2) The roof rail has a known issue of potential water seepage at the screw points due to lost tightness. This can be solved by greasing or tightening the affected areas.
3) The door seals will eventually wear down/suffer leakage. This can be solved by replacing the door seals.
4) JGC's have a known drain tube issue whereby they get kinked, clogged or otherwise cannot handle the amount of water. This compounds issue 1 - 3 if present and can be fixed by having a mechanic fix as this does require the headliner to be removed to work on.
The key is get it addressed ASAP though. The leak typically runs down the A-pillar to the floor, but on the way passes the ECL housings... so it can short your fuses or do worse damage which will cost larger dollars if this occurs.
Some were around the windshield. Others right through body welds. I do not have all details but it was worth it. That soggy carpet may be why someone traded the Jeep at a Toyota dealer.
Any idea what the cause of this leak is? Water beads up under the temperate/compass screen console in a 1999 Jeep Grand Cherokee and drips down below. Additionally, the passenger side floor is frequently soaked. Are these two separate leaks, or one?
There is a sunroof.
Thanks.
My mechanic extended that tube with a more heavy duty tube and pointed it downward so debris won't blow into it. That easy fix solved that problem, but now we are trying to figure out the leak on the driver's side. Any suggestions would be appreciated. I am in Texas. Roy
