Hi all,

During our 5 hour drive today, we stopped about 1 hour before our destination, for a little break, and because my wife said there was something dripping on her foot from under the dash on the shotgun rider's side. I assumed it was condensation from the A/C but not sure why it would build up inside.

So I get out of the vehicle, opened the hood, and there is water dripping like crazy from evaporator (not sure if its the evaporator, its the silver canister in the engine bay attached to the firewall) or its at least dripping from the a/c drain. So my ignorant assumption is that the a/c is def. not blocked, if I see all this water madly dripping away, or is it blocked and the condensation if flowing out of some where else?

So then I go to the passenger's side in the vehicle to see where the water is coming from. So I see there is a black cover, and within that black box is another black plastic box/cover, which is covered in condensation. So now I know where the drip is coming from, just not sure why that black box is covered in condensation. Never had this issue before. AC blower seems to be working just fine, blows strong.

My next thought was that the re-circulate button was on, but it was not. But perhaps it may have gotten stuck in recirculate even though the light for the button was not on.

Then I take a look toward the rear of the vehicle right behind the rear right wheel, again I see a crazy amount of water flowing/ crazy dripping. I take a look under there and see what I think is the rear a/c lines (not totally sure), I see the rubber cover or hose and looked to be some type of high pressure line (i think its for the rear a/c), totally soaking wet, but I could not verify where the acutally water was coming from.

The a/c had been running the whole 5 hour trip, it was set to 72F, outside temps ranged from 76-81.

Any suggestions or input is welcomed and appreciated! Everytime time I take a trip home for a visit to my folks, something always happens that concerns me, and always end in a repair. lol!

 

I would check both evaporator enclosure drains to ensure that they are not clogged. Any exposed metal parts on the low pressure side will have condensation on them after the system has been running for a while in a high humidity environment.

What was the outside humidity on your trip?

 

If I had to guess, the outside humidity was anywhere from 50-65%, can't say for sure. The evaporator drains have open ended rubber hoses on them correct? I'm not that familiar with a/c systems on vehicles. Thanks!

 

The evaporator drains that I'm familiar with have a lightweight short piece of rubber tubing that has the end pinched shut but will allow water to open it and flow through. Sometimes what happens is the dust and dirt in the air collect and turn into a muddy mess in the tubing. it can usually be cleared out by just poking a piece of wire or a screwdriver up inside the tubing.
