Default Lots of Condensation!

Hey guys. Just found this today. My AC system is making enough condensation to fill a 5 gallon bucket in about 10 minutes. Any thoughts on what's going on? AC is blowing cold, no other issues that I can find.

It's dripping from the main canister mounted to the firewall. I have a video if needed.

Thanks!

I'd say it's doing a real good job...IF it's draining out the tube onto the ground. Just in case you didn't know, that's the humidity it's drawing out of the cabin air, where you'll have nice cold dry air. You're probably in a high Humidity area. Mine dumps a lot too, given I'm in Houston.

Just in case it's the results of a spill inside the cabin, you might try leaving the doors open on it on a hot sunny day, maybe with a Fan blowing into the cab. That'll get rid of most of any spillage which might be there.

Hey joeincharlotte, Welcome to the Chevy Forums.

SW is right.

If you either hook up a wet vac to the engine compartment side

of the drain tube on the firewall, you can probably remove any blockages,

I have also successfully used a coat hanger wire.

Thanks guys. Was pretty humid the other day, but never seen it push that mush water. It was dripping from two spots, the drain hose was one, the canister was the other. I will clean out the drip hose and see what it does.

Here are the videos:
