A/C draining on the exhaust

I just noticed after shutting down that there was a strange sound coming from underneath. It seems that the A/C system is draining onto the exhaust. Anyone else experience this? I'm assuming there is nothing to worry about, it just seems odd.

Mine does that, also condensation drips from the exhaust making a little puddle. Never worried about it

Ac water drip

Have 2 2009 liberty kk each with same problem..condensed water from ac doesn't follow the preformed track, instead of dripping clear to the ground as designed, it (the water) has ollowed a new track dripping on hot exhaust pipe...turning heads when pulling into parking spots ...I already have rust on welds and bracket....this is NOT normal...

There is a rubber elbow that comes off the Htr box on the passenger side of the front of the firewall. It simply pulls off (by hand, but beware of hot exhaust if eng. is warm)...

If it bothers you enough you could put a longer hose on there and route it differently so that it does not drip on the exhause...then again...if you can't handle the sizzle, stay out of the kitchen!

Nosights...thanks for the reply...but..there is no draining elbow exiting the firewall in the engine compartment anywhere near the area where the heater hoses or the freon pipes are located...the water track appears to be molded into the aluminum heat shield directing the water to the drivers side...from which water ossasionally drips clear to the ground. However most times its exiting before this point dripping on the drivers side exhaust pipe. As I said I have two Libertys and the defect is in both.

There should be a small 90 degree elbow coming off the lowest part of the htr box...it is only about 3" long and if you stand by your right fender you should find it on the firewall (a flashlight will help), look just above and outboard of your right exhaust manifold. If it is missing you will just see a short (~1" long) piece of plastic tube sticking out (generally this also results in a wet pass floor if the elbow is missing).

It is easiest to find while the Jeep is running with the A/C on so you can see the dripping.

Leaky Fix

Thanks again Nosights for responding...but...there is no exposed drainingtube on the 2009 model..There is an aluminum heat shield covering the firewall. In it is a premolded track for the water to follow. If there is a tube it probably drains to the area above the transmission. A molded channel,in the heat shield is visible running down the driver side above the left(drivers side exhaust pipe, just past the pipe-manifold union. At time water exits at the opening, at the bottom of the heat shield..now heres the good part... a mounting bracket for what appears to be brakes lines was cut through the shield next to the water channel..the water escapes from this 2 inch opening, running on the outside of the shield dripping on exhaust pipe...someone wasn't thinking at JEEP... A piece of aluminum duct tape applied to the hole keeps the water in...so far...There should be a service advisory issued for this..don't you think?

I hate to revive such an old thread, but I was wondering if this is still considered normal and should be ignored? I just bought a 2008 Liberty, and mine also drips water from the A/C onto the exhaust, making a sizzling/hissing sound every time you park the vehicle.

Yes, it's normal and should be ignored. No harm is done. It's just water.
