Try taping some fine mesh wire / chicken wire over the vent input, stops the leaves going on there in the first place.

I read all the horror stories so that's what I did and have never had a problem since.

I have a 2001 Jeep Grand Cherokee laredo. Passenger side rug gets soaking wet when AC is on about 1/2 an hour. What is puzzling me is that the condensation is dripping nicely from the exterior drain. Could there still be an obstruction?

I have a 95 JG which has the AC problem. After a 13-hr road trip one weekend, the back passenger side floor had inches of water. If anyone knows where I can get a manual for diagrams of the AC unit, please post such resources on-line. Thanks!

I have a 1997 JGC and have attempted to clear the drain with a hanger. There does not seem to be anything coming out. I have read all the suggestions, but am unsure as to the best way to deal with this problem. I am going to try the compressed air, but there is no good way to get to the downward drain that comes from near the window. Any better ideas on how to clear that drain? I do get a little water when I try to pour water down into it with the "plug" out inside the car.

I have a 1999 WJ. My son brought his 1996 ZJ (JGC) to me with water in the front and back passenger floor boards. I tried drilling and cleaning the AC drain as suggested earlier, but it was clear and flowing. I pulled off the cowl cover (you have to remove the windshield wipers, then it just lifts up) and found it was full of leaves, composting nicely. The compost had plugged the small water drain slits at the bottom of the steel panel that the screen is pinned onto. Behind the screen was clean, but outside was completely full of leaves and clogged. Rain water (we've been having a lot of rain) was filling up this cavity and leaking around the AC air intake box, down the firewall, and even off the AC blower motor. I confirmed this with a garden hose spraying water on the windshield. We cleaned out the area and removed the screen and made sure the area behind the screen was clean. I sealed the AC air intake that juts up into this cavity with a flowing silicone seal. We've had six inches of rain, but no more water on the floor. Note I also cleaned out the doglegs in both front fenders (see them at the bottom of the fender with the door open looking forward). They were clogged with leaves and compost too, and were holding water. Use alternating compressed air and a garden hose. Also the vent slots at the rear near the tailgate, and various other places. Keep these clean. Even if it doesn't cause leaks it will eventually produce rust through.

If memory serves me you have to remove the gas tank to swap the fuel pump and the part alone costs about $350. I'd pay someone to do that one. As far as dash goes, think of it this way $450 @ $60/hr. = 7.5 hours for a pro. The question is, can you do it in 7.5 hours if you've never done it before? When I plan a weekend repair job I usually double the time quoted by the shop.

Wow, This is an excellent resource. I have a 1998 GC Limited with the 5.2 V8. I bought it as the second owner with only about 60k on it. I have really enjoyed this truck with the exception of the gas mileage. I only get about 14 - 15 miles per gallon; if anyone knows any tips that might help with this, it would be GREATLY appreciated. I too have had the issues with the water in the floorboards on the passenger side. After looking all over this truck, I eventually came to the same conclusion that others have. I can spend less than ten dollars, and insert a plug that can be cleaned out when needed, or take it to the dealer for $850 and have the same problem in a few years. Overall, the Jeep is a great truck, and does all I need; even pulls my 29' travel trailer. Thanks for all of the great comments on here. I have seen several things that will help me save on future repairs to my GC.

1998 GC. I'm having the exact same problems. Water front and back and even UNDER the rear passenger seat. The smell is just nasty. I thought it was rain water, but it seems to keep coming. Must be AC condensation.

Where can I find a good diagram so I know what I'm looking for? Don't want to just randomly pull up carpet.

I have a 1998 Jeep Grand Cherokee Laredo (special edition). Here recently, the AC quit working. In the past while running the AC, it has had momentary lapses where it would cut out and quit working. I would then turn the AC knob off and on, and it would begin working again. Just the other day, it cut out and has not turned back on since. When turning the knobs, no air is blown through the vents, nor do I hear any fans running. I am not knowledgeable of cars, so I don't know the exact problem. I am told by others that it could just be the knob connection, the AC itself, the coolant, or the fan motor. If anyone can give me a reliable diag of the problem and a possible fix, it would really save me a lot of money in trying to correct the problem. Thanks!

I have a GC Limited 1996 and love it. I have the same problem with AC. Dealer wants $90. I have the shop manual, but there is no diagram showing where the AC drain is. I found where it is supposed to be, but my question is what size hole do you drill? I drilled one and ran a wire about 2ft, but it still clogs up. Ideas?

1998 Jeep Grand Cherokee- I believe a/c parts are defected. heat coil fails-vehicle a/c blows out cold air in winter. evaporater coil fails - vehicle a/c blows out hot air in summer. why is there no recall for this? it appears to happen in a lot of Jeeps.

I just purchased my JGC last week. So far I love it... well minus the water on the passenger side of the vehicle. I noticed some one had already drilled a hole to clean the debris. The "plastic piece" used to cover the hole fell right out when I touched it. Once I looked into the hole I noticed there were two other plastic covers that had fallen into the hole.. I guess in an attempt to fix the problem previously. I have two questions for you Jeep experts. First, what is the best way to prevent mold from growing on the bottom side of the carpet. Second, I cleaned out the area around the drilled hole and turned on the AC. There was air blowing out from the hole, does that mean the drain is clean?
