    I checked the truck in the driveway and there is a water drip under the truck. It seems to be coming from behind (cab side) a silver colored plate just behind the catalytic converter. The passenger side floor is soaked (standing water) but I can't see wwhere its coming from. Do I need to remove anything to get a better view. The two cooling lines in the engine compartment are cold and seem to be sealed tightly in the fire wall.

    Water has no flavor or smell and radiator still full. What do I need to remove to see the hoses on the inside of the cab?

  • kbmack Sep 27, 2009

    I need more specific directions for checking interior leak. Only occurs during heavy AC use. Collects in floor board on passenger side.

  • kbmack Sep 27, 2009

    Solution makes sense. Thanks.

It will be just below where the heater hoses enter the HVAC compartment on the engine side of firewall, there may be a rubber drain tube nipple closed on the bottom to keep dirt out but let water drain,take a small straw and push up to unblock, then take compressed air and blow out ,if you want to do a thorough job remove dash(VERY TIME CONSUMING) and spray out with water and clean evap coil but the other will suffice

You do not have a place to unclog drain, the water comes from over ice building on the pipes and condensing unit…you need to follow the line and seal the inside housing it should be draining in the engine side not the cab, see if you can use foam or silicon sealer to close the hole, and let me know if that work if not we go to the next step. Please see that grant me your approvals by rating my service and I hope that I can serve you again the future. I will work with you in this issue to conclusion

    Are you sure the water coming from the cooling system not from the heating hoses? If it is too much try to move ant part that block your view without allowing you to start the car and recheck it…if it is too much water it may be coming from another place check the water level in the radiator to make sure and let me know. Please do not forget to grade my assistance so I am able to continue to provide you with better service. I will be working with you to conclusion of the issues.

  • Norman Al-Anbar Sep 26, 2009

    Do you see any removable cover that is close to the source of the water? Do you see the water coming when you start the car or it is just dripping? as we stated the water source is condensation from the air conditioning, heating pipes, the cabin not sealed and water comes when the car comes in contact with water, so we need to eliminate one by one, first we need to know if you can see the water coming and how much and what are you doing at the time, i.e starting the air, starting the car, raining, etc. After that how much water and the source, then finally fixing the issue. Now you need to see if the water coming to through the firewall or from inside the cabin, so try to see anything that you can remove to see the source and let me know. Please do not forget to grade my assistance so I am able to continue to provide you with better service. I will be working with you to conclusion of the issues.

2008 Toyota Tacoma V6 Would the AC drain hose drip water onto the frame even if the AC was not used?


If there was a partial blockage in the drain at the ac box it is possible that water will still drip out over time . However some Toyota ac units use the same box for the heater core so I would be looking for a coolant leak in that area . Check coolant level and have a pressure test done on the coolant system to check for the leak. If the drain is in the frame under the car ,the water may be also from the windscreen plenum chamber that collects water from the windscreen and drains in that area.

Water leaking into cab interior ac on


Your condensate drain is plugged. Your evaporator case("inside coil") is sweating and the sweat is dripping into the footwell. If you can fit yourself under the truck, just behind the rigght front fender, you'll see a small-diameter rubber hose hose coming out of teither the firewall or the floor. Find a stiff wire and gently poke it up the hose. If it goes in really easily and really far, the problem is that the hose is off at the evaporator case inside the truck.

The drain on your evaporator core housing is most likely plugged. Condensation on the evaporator core drips down into the plastic housing and drips onto the ground through a hose on the firewall on the
passenger side.

Find the small hose on the firewall in the engine compartment. You should be able to pull off that
hose and see if its stopped up. If the hose is ok, you may need to remove some of the ac ducts
under the dash to get to the evaporator core housing to unclog the drain hole.

I have no doubt that thats the problem.

'98 GMC Sierra is leaking water inside the cab on the passenger side when I have the A.C. turned on. I can see where the water is coming from, but I can't get it to stop leaking.


There is a drain under the vehicle under where the ac lines go into the vehicle cab',look directly below the ac lines,it is hard to find but it is there ,use compressed air ,like a air compressor or air tank,with a blow gun and blow the drain out,if it unclogs the drain,it will pour out like a water fall,if this was at all helpful,please rate thank you.

I have a 2008 Elantra, and water is dripping on the passenge side floor. I suspect that the AC drain tubing is blocked. Also a swooshing noise can be heard when making a sharp left hand turn. How can I...


They can be hard to find. Do you remember where the water dripped on your driveway after parking. That's where the water came from. It will be in the area of the firewall since that's where the evaporator is located. It may drip on the frame and run down from there so you'll have to get under there when the engine is not hot and use a flashlight to look everywhere. If you're lucky a little water will still drip helping you find it. Blowing through the drain hose is the best way to clear it. Compressed air is even better.

That sounds like the AC condensation drain tube/hose is plugged up.

The AC evaporator/core condensation drain tube is located on the passenger side of the fire-wall towards the bottom of the fire-wall, (it resembles a heater hose that is coming off from the fire-wall and it connects to nothing, and it is just to drain the AC condensation) and it is easily viewed from under the vehicle. Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that the AC evaporator/core, or the heater core is not damaged from using any hard or sharp objects to clean out the AC drain.

Water is dripping from outer heater unit and soaking passanger side of front carpet.


There are two causes of fluid dripping from the heater core/ac evaporator housing. First, if it is running inside the vehicle and getting the carpet wet as described then it is most likely a bad heater core leaking antifreeze into the cab. Secondly, if it is dripping outside only when the a/c or defroster is running then it is the normal expulsion of condensation and is harmless.

AC works fine but water drips on passenger side


this is normal, water is the condensation leaking out,but if leaking inside the van then the drain is pluged up, the drain is on the pass/side outside the van on the firewall,blow air into drain or stick a coat hanger in to hole until water leaks out,
