smokin5s Posted July 22, 2002 Report Share Posted July 22, 2002 My mother's A/C in her Grand Cherokee Laredo leaks. Whenever it is turned on, the passanger side under the seat gets really wet. Any ideas what causes that and how to fix it? Quote Link to comment Share on other sites More sharing options...
GRN96WS6 Posted July 22, 2002 Report Share Posted July 22, 2002 Sounds like her heater core needs flushed. Get a Haynes manual or take it to a shop if you do not want to do it yourself. Quote Link to comment Share on other sites More sharing options...
Maro Posted July 22, 2002 Report Share Posted July 22, 2002 There is a catch pan that the evaporator is mounted in. It is supposed to drain all the water that condenses on the coils to the outside. There should be a drain hole in the bottom of the "box" near the firewall (engine side). Check to make sure the drain port is not plugged. I'll bet it is....

smokin5s Posted July 22, 2002 Author Report Share Posted July 22, 2002 where is the drain port at? by the heater core? isn't the heater core inside of the dash? Why would they engineer the car like that? What does the drain port look like? Yeah, I'll do it on my own as long as I can. Quote Link to comment Share on other sites More sharing options...
Maro Posted July 22, 2002 Report Share Posted July 22, 2002 It is usually a rubber valve that allows water condensate to drain out to the ground. This is why you always see a water puddle when a car is parked with the A/C on. A/C works by passing the incoming air over the cold evaporator. This quick cooling causes the water vapor to condense, thereby, drying and cooling the air. Lay on your back under the passenger side (where the A/C hoses enter the firewall) and look for anything that looks like a drain. I usually will use a pencil to poke the plug loose.

smokin5s Posted July 23, 2002 Author Report Share Posted July 23, 2002 normally, but also, your compressor can be broken or something. You'd have to check. Hey, does anyone know what kind of Freeon the cherokee's use? I'd like to get that fixed for my mother if I can. Ok, is it the heater core or the evaporator line?

GRN96WS6 Posted July 23, 2002 Report Share Posted July 23, 2002 Depends on what year the car is as to what type of freon it uses. It should say under the hood somewhere though. Or look in the owners manual. Quote Link to comment Share on other sites More sharing options...
