AC Leak?
 
On passenger side in my 94 rx7 fd, it keeps leaking something. Looks like hazy water and dries up into a white residue. I think its an AC leak. What do i do to fix this? and if i cant, what would it cost in parts and labor (at $90/hr) to get it fixed?

Is the water coming out only when you are running the AC?
It is probably only condensation coming out from the evaporator drain.
This is normal operation.

yes, only when im running the AC. Normal operation meaning? normal for it to happen or? because my carpet is getting wet lol

Ah ok you didn't say where the leak was appearing. Yea the evaporator in the ac system inside the dash produces condensation, which is a supposed to drain out of a drain tube to under the car.
Sometimes a wasp type insect will make a mud nest inside the drain tube and clog it. Then the water backs up and leaks in the car.
Check the drain tube for obstruction, and I believe you can access it in the passenger footwell also.

if i pull it out the hose on the passenger side footwell, will it start gushing out with fluid?

If the hose is completely clogged it might still have water accumulated inside. Place a towel down there before you detach the hose just in case. After you inspect and clean out the drain tube, make sure it's not kinked when you reinstall it.

So I found the leak is coming from the top part of the hose where it connects to the condensater or whatever. Attachment 753520

What do I do to fix it? No blockage or anything in the black little hose, just leaks where it connects.

If you can get the car up on a rack or even ramps you can get some coil/condenser cleaner. shoot the cleaner up through the drain hose into the evaporator box. it will emulsify the mold/algae/fungus/dirt in the box and water should drain out of the car through the hose normally. You may have to repeat the process a couple of times to get all the gunk out. If you have a cabin air filter you need to change that also.

If for sure the hose is free and clear of obstruction, I would try to see if you can get a zip tie around the hose to put some sealing tension on it and see if it stops dripping out.
Doesn't need to be super tight or anything because there is no pressure in that hose. Just tight enough to make leak free seal.

haha I literally did that 5 minutes before you posted it :) Thanks for all the help, I think that should do the trick. Ill find out real quick on my way to work tomorrow! :icon_tup:

One last thing, where does the hose dump off to? like an area of the car where it then drains out of a hole?

Andre The Giant 08-05-15 07:34 AM

Yes it just drips out of the tube to the ground below the car
