Home Forums Hunting & Shooting Hunter's Campfire Car AC drain hose

If it gets plugged up it'll allow the condensation to soak the carpet in your floor boards.

Mine did that. I just got finished crawling under the car, finding the drain hose exit, and poking a piece of wire up in it to unplug it.

Don't be under the hose. It's going to pour water out when the plug comes loose.

You probably have Legionnaires disease now.

Add it to the list.

Logic 101.

LOL

Actually, I had never heard of the AC drain hose getting plugged up on a car. But it's apparently a fairly common occurrence. There's quite a few YouTube videos showing how to fix it.

The hardest part of the job is jacking the car up and putting it on jack stands. Once you find the hose, it's just a matter of poking something up in there to unplug it.

Some videos show people ripping their interior carpet up to get to the hose from the inside.

They're either dumb or too cheap to buy a jack and some jack stands.

I pulled up the floor mat on the passenger’s side of my F150 to vacuum the carpet and discovered chit actually growing in the carpet! Turns out the wisdom of Ford’s engineers was to cut the drain off right level with the firewall so all the discharge got blown back in the carpet. I found a 90 degree elbow that fit it and solved the problem. Haven’t had one stop up yet though.

Clogged or cracked... fairly common

My Toyota truck drains into the wheelwell. Maybe that's to keep someone from sticking their head under it when they use the pokey thingy.

Never had one plug up on any vehicle ever. I have owned most major brand automobiles, at one time or another. Curious what vehicle you have?

2011 toyota camry

Somebody who lives in the Communist capital of North America is on the rag.

What a surprise.

The daughter has a 2012 Camry, I'm going to check hers, next time she's over! Thanks.

Won't matter if a bug or wasp gets up there.

They don't care, foreign or domestic, truck, car, SUV or micro bus.

Another thing to watch for, is the drain tubes for sunroofs. A neighbor of ours bought a used Hummer H3, and it started leaking like a sieve around the sunroof. It turns out that the drain tube was plugged and it soaked her carpets, and damned near everything else in the vehicle's front seat area. She had traded off a really reliable car that gave her zero troubles, for that POS that caused her nothing but grief. She wanted a bigger car because her kids were getting bigger and had more troubles getting into and out of her Altima coupe.

Common denominator with A/C drains and sunroof drains seems to be where the vehicle is normally parked.

Close to trees will usually allow debris into the blower housing through the fresh air intakes and around the sunroof weatherstrip. The leaves and tree bits decay and form a thick sludge that causes blockage. Some cars are more prone to it than others due to the design and diameter of the drains.

Im trying to remember when I poked something that didnt respond with one kind of ooze or another?

In dusty areas, the dust comes in through blower intake and can get into the condensate - any kink or squeezed place in the drain tube eventually may cause a muddy condition there - when it dries it makes the blockage even more troublesome.

Some insects seeking moisture will crawl up into the tube when it is wet - dead or stuck bugs, or their little leavings/nests, will cause the same problem.

Best preventive seems to be adding some Drano to the refrigerant. TIC
