Air conditioner icey water leak problem

[Vee-ard]

Having a bit of a problem with my air con lately, when I have the aircon on it will after a while start leaking icy cold water out from the centre console onto the drivers feet, the other side seems to be quite dry. I have already done a ffs search and unblocked the drainage lines underneath the car near the tranny. A bit of crap came out but not a whole lot, so now Im at a miss as to what is causing this cold water to leak out everywhere. Firstly, what is causing this?

Secondly, It seems to be worse when using the vent controls and setting them to outside air, it doesnt leak as much when the controls are set to recycled air, obviously because there is less humidity for the air con to condense? (I live in broome). Now, as well as the heater core having a slight leak (not that bad) does the whole dash need to come off to fix this air con issue? because if it does, I may as well replace the heater core at the same time ($$$$$)

What's everyone's ideas on this? <---- this is me right now.

Your floor drain is blocked.

Jack up the front of the car and climb under.

The drain is located on top of the transmission hump, above the box. There should be a rubber grommet in the tunnel, with a wire insert pushed into it. It can be a bit awkward to see so you will probably need a torch.

Grab the insert with pointed nosed pliers and just pull it out. Water should flood out and the insert will probably have a fair bit of crap on it.

Allow all the water to drain, clean the insert, replace it and your away.

If you bothered to read everything that I wrote, I've already done this.

How far up the drain tube did you get with the cleaning? Leaves and dirt etc. can block the drain at the base of the evaporator case, not just the tube end. Maybe try coat hanger wire with the end bent over into a loop (to avoid damaging the polystyrene insulation in the evap. case) to ensure the case drain is clear. You might have to do it a few times because the leaves will be spread across the bottom of the case and what you can't get to will wash back into the drain end.

Clean the plenum at the base of the windscreen to prevent it recurring.

Thanks cheap, i'll give it a shot again. Hopefully this is all it is.

Well, pardon me all to hell for missing that fact and trying to help.

Don't worry, though brother - it won't happen again.

mate no offence was meant, and I appreciate any input, but if you arent going to read what I wrote and answer the question accordingly, you're no help anyway. Dont act hard done by.

poking wire up the drain tube can sometimes break the foam insulation from the inside of the box cause a blockage once the wire is removed .
using a 25mm or larger and a match grommet drill into the side of the box from the passenger side in the lower left corner of the box above the tranny hump and inspect the inside of the a/c heater box for any debris covering the top of the drain tubes you should be able to see the top of the anti block wire if fitted once yo are satified its clear install the grommet to reseal the box , close all the vents and turn on the a/c and the fan on high wait afew minutes and see if water is then dripping from the drain tubes ..

It would appear that you didn't clean it thoroughly. The suggestion to check your drainage point would be anyone's first thought. Even if you took it to a mechanic and you said that you've checked it, they should check it anyway for their own piece of mind.

Instead of contradicting yourself in your reply, give the guy a break..... He was trying to help. If you don't want suggestions, even checking what you've already done, then take it to a professional and pay.

It's really not our problem, and to be aggressive about it doesn't help!

I did take it to a professional who also cleaned the drainage lines after I did it, he got some crap out, but its still leaking. Half hours labour he charged me.

Also, there's no contradiction, input is only input when it's relevant.

[scozz76]

Take it back and tell him it's still leaking

[Vee-ard]

I did, and he wants to take the entire dash apart (10 hours labour, no car for 2 days), and I was thinking this isnt so bad because I know my heater core is rooted (and it'll cost me the same to pull the dash apart to replace that anyway), If i dont cable tie it off under the bonnet, it squirts hot water under the dash, but this ice water thing is pissing me off too. I cant live without A/C on up here.

Fine. Just try to be a bit more gracious when someone tries to help, instead of putting them down. Your response was rude and ignorant, for no reason. If you're pissed off because you can't fix your problem, don't get the shits when you ask for help and people actually try to assist you.

And I'll stick by my first post - it's blocked, somewhere.

I agree with Calaber on both counts . But seeing as we are all nice people on this forum I'll suggest you try using a air duster gun up the drain holes....don't use full pressure, just enough to dislodge whatever is blocking the drains. This won't remove the crap, just relocate it to where it may not block the drain. Not a permanent fix but better than nothing.
I'd also suggest you don't use the vent control outside air setting as it allows all sorts of crap into the system plus it does not cool as efficiently as recirculated air.
Re the heater - the dash does not have to come out if you cut the heater pipes (there is a how-to) but for Broome just totally isolate it and join the hoses before they go thru the bulkhead.
The extra moisture from the leaking heater plus the high humidity of Broome is probably overloading the vents anyway.
