Excessive water drain from AC

mtb_rider · 07-28-07, 07:19 PM

So I've been running around most of the afternoon with the ac on, and seem to have a lot of water draining from the drain tube in the firewall. It is dripping a couple times a second, and within just a couple minutes I have a dinner plate sized puddle and it starts to run the length of the rig. It is only around 80 or so today, and have been driving mostly highways. I know, or at least thought it was in need of a little charge. Would this explain it, or do I have some other issue in my ac that may be causing this? Thanks.

Sounds normal to me. The amount of condensation has more to do with the humidity than the temperature. Mine always leaves lots of water on the ground. The same goes for my little Honda Civic, and my wife's honda civic. I wouldn't worry.

this is not cruiser related but my dads tahoe had the same problem that just occured on a recent road trip, and his condenser went out, although the AC still worked fine, the amount of water coming off the unit was much more than usual, while the vehicle was running it had a consistent drip probably every few seconds, while parked it would accumulate a puddle that would flow down the street like an open faucet.

personally, i run my ac all day in 95 degrees plus and my puddle is nothing larger than say a 6 inch round puddle.

there is no correlation to the amount of water coming off the evaporator core and a problem... ie more water must equal a problem.

Its more of a question fo relative humidity where you are. High humidity equals
more condensation....more water draining from the evaporator, low humidity the exact opposite...less water drainage.

My only concern about the water drainage is that it does in fact drain where its supposed to, and when the A/C is working. If the A/C is cold and the evaporator drain is not restricted, then I have no concnerns about the amout of water if gives off.

this is a non-issue.

It the A/C is working and you have a waterfall under the hood...be happy and enjoy the cool air.

The air conditioner also functions as a dehumidifier... as the relative humidity increases, so does the run-off.......

Thanks for the responses so far. It is draining properly, I had just noticed that it seemed to be more than normal. The humidity didn't really feel that high today, though I haven't seen the forecast. Likewise, we didn't have some very unusual for our area high humidity (Portland, OR area) early this week/late last week, but I didn't run the AC much as it wasn't that hot, so don't have much to compare it too.

My 60 drips more water than any other vehicle with AC that I know, but it is all good with me!

My 60 drips dinner size plate of water when I run the AC and I live in a very low humidity place. Sounds like it's normal.

can you tell me where this drain hole is located as I am trying to find mine....today when turning I had a half a cup of cold water come out of blower housing on foot inside vehicle. Parking in drive there is no water dripping with AC on RECIRC and HIGH and should be given our 80-95% humidity mixed with temps in 90s. I got a feeling it is clogged and collecting in bottom of plastic housing and I happened to slosh some out.

Thanks for any help or graphics to show drain hole in firewall and also how to get to it from inside to check if clogges.

Its normal. Mike

There is a small rubber hose on teh firewall about 1/2 the way down, on the passenger side. Water is suppose to drain out of this hose. If it does not, you are probally getting a we carpet on the passenger side. Take something like a small plastic tie strap and try to unblock the hose. If your in the South...expect a good bit of drainage when the AC is on and humidity is high.

No hose was sticking out so pulled down carpet and saw the hose that goes from plastic portion through firewall...disconnected from this end and got 4 cups of water out of it before it slowed to a slow drip...so put a finger from some rubber gloves over it and pulled back through rubber hose. It was not blocked but must have been crimped or folded on end as it was not protruding from firewall on engine side at all. So I got another piece of hose and connected them to make sure it would be long enough and made sure to put back through firewall all the way and then connected to air conditioner. Put zip tie snugly around to hold into place so no feet will accidentally knock it loose....and ensured it now came through firewall completely.

Turned on AC and it started dripping...perfect!
