Air Conditioner Drain

I have a 1997 Jeep Grand Cherokee and the A/C condensation tank is clogged causing water to come out of the back right vent inside the car. Jeep service said the condensation drain is clogged and needs to be cleared. Where is it? How do I find and unclog it? Do you have any diagrams showing how to do this?

Thank you

Should be real easy to find. Normally on the right side and will be a simple hose about 3/8" or so diameter coming out of the firewall in the engine compartment and dangling down. May need to get it up on ramps or jack stands (be safe, not just a jack) to get a better view. To unclog you will likely need to remove it. If the clog is INSIDE the evaporator housing instead of the drain line, that will require some disassembly to correct.
In some vehicles you can see where the hose connects inside to the bottom of the housing, others are not so visible.

tow guy---on every other car it's easy to find, not jeeps. it goes out of the heater box and into the frame, he would be looking forever.

marcon--sit in the passenger seat, look at your feet, right above that on the floor/firewall area is the lowest point of the heater box, a 1-2 inch round part that sticks down like 3-4 inches and made of plastic. you need to drill a 1/4 inch hole straight into that and remove all the gunk you can get out, use a coat hanger, screwdriver, even compressed air if you have access to it. there will be perfect black compost that you can put into your garden inside that. chrysler issued a bulletin for us to do that versus taking the whole heater/a-c box out. the bulletin allows .2 hours to do this, expect to pay at least 1/2 to 1 hour labor if you farm this job out. then after it's clear, simply push a rubber plug into it to seal it.

let us know if you have more questions

LOL; that's to make sure the frame rusts out even faster?
