Where is the water drain in the a/c system on my grand cherokee?

Question

I have a 1993 jeep grand cherokee. i have been all over the bottom side of it looking for the drain. all the water is in the passenger side floor. is the drain behind the heat shield?

Answer 1

Open hood (have Flashlight) look down the firewall area on the Passenger side and close to the frame area there should be what appears to be a small tube hooked into the firewall but not
connected to anything at the other end and pointing to the ground
This tube will likely be constricted/plugged/pinched or something
that does not allow the condensate to run out and instead leaks
into the floor of your vehicle...

Answer 2

It's located at the bottom of the evaporator case which is located on the left side of the vehicle's firewall from the orientation of being seated in the driver's seat. You'll probably have to lay under the vehicle and look up to see it . If the case is leaking into the passenger compartment. It is usually due to the hole or tube at the bottom being plugged,clear this and your problem is solved.
