Where is the drain hose location on a 94 Jeep Grand Cherokee?

Answer 1

Hey Bo== It should be under the hood, against the firewall on the passanger side at the botttom of the evaporator case.Be careful unstopping it as the evaporator is just above the case and can be punctured. GoodluckJoe I dont know about the '96 but I just spent a couple of days cleaning and Surfing the net to determine the best options availiable. As it turns out the 1998 Jeep Grand Cherokee A/C drain dumps into the frame rail. If you look up under the frame rail the discharge is coming (or supposed to) out of the first large (1/2 x 1) slotted hole. I was lucky and only had to flush that area out with the hose and it fixed my problem - so far. From what I have read in the last couple of days it could have been a whole lot worse. If the cleaning poking and prodding hadnt worked I was going to drill the 1/4 inch hole in the cab side duct (vertical face of the circular area just above your feet and approx in the middle of the duict. - the drain is supposed to go away and down from this location and into the frame rail) and use a coat hanger to see if I could feel a blockage. If that didnt work- God Forbid - it was going to have to be the disassembly of the interior to remove the A/C assembly. From what I read it a 6-18 hour job depending on your luck. Some posters even suggest that that is a good time to buy another truck. I think I may have givin that some serious consideration had it come that far. Thanks to all the posters on this site and the rest of you too posting the net. Sorta makes you wonder what we did before it. Good day and good luck. Don't know about a 96 but on my 95 it is under the dash on passenger side floorboard. You have to pull up the carpet and padding, on the vertical rise part of the floor board you will see a plug in the middle of a small black cylinder part of the duct work that comes through a circular cut out in the floorboard. Pull that plug out and get a long wire and run it in the hole, several times. The drain hole runs into the frame rail of the Jeep, you can't reach it from the bottom. You will have to seal the plug, get a new one, or make one(I cut off a section of a pencil and epoxied it) to reseal the duct work. I drilled two holes in the floor board to make sure it stays dry because it still condensates some on the duct work, it gets a little bit of condensation on the floorboard still but the carpet and padding stays dry. http://home.sc.rr.com/janet/TSB/24-06-96.htm Look on the pass side of the car against the firewall and there should be a hole or indentation in the evaporator case, Be careful cleaning it out as the evaporator is about 1 inch above this case and can be damaged with a sharp instrument.

Check under the passenger side dash. You should see a black tube running down at an angle that comes to a stop with a round end about the size of a half dollar. If you are getting water in the floorboard there is a fix that you can find on the web to unplug the drain. If you need more help on the fix or pictures of the exact location of the AC drain please let me know. my email is buckeyejh@comcast.net. Jack

Answer 3

If you mean where does the water come from? there is no drain hose, the water is from condensation that forms on the condenser. If you are talking about the freon you have to have it serviced.

In the 1990 Jeep Cherokee Laredo, you can find it pointing down under the car, on the front side of the firewall. Find the suction tube and liquid tube for the a/c here:

http://autorepair.about.com/library/faqs/bl406i.htm

The a/c condensation drain is straight down from that. It gets clogged with dirt/leaves. You can stick a wire up it to free up the gunk. Just wiggling the end of the tube allowed mine to flush out the dirt and the water just poured out. Gravity will help with this.

On a 1998 Grand Cherokee the drain is inside the right "frame rail". You have to pull the carpet back on the passenger side, drill a hole where the plastic goes out and clean it out with air pressure.

Answer 4

The drain runs into the frame. In order to clear the drain you need to pull back the carpet on the passenger side. There is a rounded area in the molded plastic cover. You need to drill a hole in the center of the rounded area. I use a coat hanger to clear the drain tube. Use caulk and a large headed screw to seal the hole once you are finished. Remember to set a pan on the passenger floor. That system holds alot of water.

Answer 5

It is located in the engine compartment on the passenger's side fire wall about half way down. May be easier to get to under the car. Just take a screw driver or similar object and put it in the tube to unclog it. Compressed air works good if you have it. Just be careful to not put the screwdriver in too far or too much air pressure.

Answer 6

The drain hose does not actually exist. The evaporator box (also holds the heater core) is partially in the engine compartment and partially in the cab on the passentger side and excess water from running the AC drains immediately into a frame member. This is a unibody vehicle. There is no way to access the end of the drain tube to clean it out. I suspect you may be experiencing water on the passenger floor, perhaps front and back? Maybe a foul odor? Maybe no cold air even though the rest of the system checks out ok? Check the archives here in Wikianswers. You will find several very detailed accounts of this issue and what to do about it. Basically, they're all bad news because of the poor engineering that went into this aspect of the Grand Cherokee.

Answer 7

In passanger side frame rain, good luck seeing it. Try using a sniffer on inside of vehicle if looking for a refridgerant leak.

Answer 8

It is an open drain about 6 inches from the oil pan under the passenger side.

Answer 9

On the top of the transmission tunnel.
