2015 Grand Cherokee AC Drain

Can someone point out where the AC drain is on this vehicle? When my AC goes to drain water it comes from this location (see attachment) Is this correct? Doesn’t seem like it. Thanks

The AC drain is a short hose that runs out the engine side of the HVAC housing through the firewall and exits in the engine compartment. The water could drip anywhere from there.

I hear its easy to get the HVAC installed with the drain pinched or draining onto the passenger compartment.

So i’m assuming my AC hose is either pinched or clogged if it’s dripling from the AC line instead?

That's what happened to me, the dealer replaced the evaporator and pinched the A/C drain shut when they put it back together. I had to take it back in after I heard water sloshing behind the dashboard and the driver's side floorboard became soaking wet. They had mangled the hose so badly that they had to replace it. Now it is draining but the water that was there before is still trapped and is sloshing around and still soaking the floorboard. Don't know right now what to do next, hoping Chrysler corporate can help me out. I don't want to take it back to that particular dealer ever again.

My 2015 (5.7 Limited) drips from this same area. I have always assumed that the drain outlet is somewhere above this connection, but I haven't gone looking for it.

I believe the water you see dripping there in the picture is from the REAL AC drain line. The part you have circled in the picture is not part of the AC system, I believe you have circled the transmission cooler bypass valve. So it appears when looked at quickly from under the vehicle that the water is actually leaking from the transmission cooler bypass valve, but there is no water in those lines, it is transmission fluid in those lines.

The AC drain is above that, sticking through the drivers side of the transmission hump. The drain only extends through the hump about half an inch. Then the water drips where ever it chooses and the transmission cooler bypass valve is directly underneath it.

In the picture above that Cold Case provided, the drain looks like a long tube, and it is, but all that tubing is in the vehicle and only the outlet sticks out of the transmission hump on the driver side. So look above that circled part in your picture, and about 6 inches above it you will see one end of the drain tubing sticking out of the hump, and if the AC is running you should see water flowing out of it.
