It will be a small hose with an open end, it's on the passenger side of the firewall, inside the engine compartment, it's black and held on by a small ring clamp. It comes out of the firewall and turns down pointing at the ground.

I can't find the evaporator drainage hose anywhere under the truck. Is it possible that there isn't one? I've looked all under the passenger side of the truck. Does it come out from the box that sits...


Some evaporator drains can be seen from inside the cab pull floor carpet back alittle and follow HVAC case it may be inside or yes the cold air hole can be the drain but these drains do not drain right away a good test is to turn a/c on set to the coldest position and fan on the lowest position in a dark area such as garage with hood up watch a/c compressor the clutch will cycle on and off once it does this for 10-15 minutes pull car into the sun and shut it off then it should drip some water out the drain hole recheck the blow hole now.

Water coming through air vents


clean out the drain under the windscreen and ensure that the drain hoses down inside the mudguards are not blocked . ON the dash controls close the vent to recirculate the cab air and not allow fresh air into the cab.

2005 land rover lr3 is leaking water into cab only when heater is on


sounds like a dodgy heater element. there is a small heater radiator located inside your blower right next to your air conditioning radiator. check that and any hoses around it for leaks and damage.

Where do I locate the air condition water hose drainer? The a/c hose drainer is not draining any water at all, I do not see any water draining under the car, so, whenever I used the a/c, the cold water...


Hello,

The drain hose does not actually exist. The evaporator box (also holds the heater core) is partially in the engine compartment and partially in the cab on the passenger side and excess water from running the AC drains immediately into a frame member. This is a unibody vehicle. There is no way to access the end of the drain tube to clean it out.
The drain hose runs through the firewall and into the frame There is no way to get to it from the outside of the vehicle. The only way to relly reach it, is to remove the housing.
Sounds absurd,but that's the frantic truth about this car..

Good luck.

2002 Tacoma, water leak inside cab from air conditioner, where is drain? How do you unplug this drain?


Wear eye and face protection use a long philips screw driver. Go under car and look for a/c condensation hose. Ususally by firewall on passenger side of truck. Unplug the drain by inserting screw driver into hose and allowing water and debris to drain. Caution don't push screw driver all the way in and don't get too rough you could puncture evaporator.

Windows in truck are fogging up


Need more info: I assume you are talking about the side windows, right?
Do they fog up when the truck just sits? Does it make a difference what the outside temp is? Does it small like anti-freeze (sweet smell) in the cab when it happens?

The first and easiest thing to check is drain tube from the air conditioning unit. Air con units are dehumidifiers and the water that they condense from the passenger compartment is supposed to drain out. If the drain gets plugged, then the water sits inside a little reservoir under the dash on the passenger side. From there it goes right back into the cabin raising the humidity and fogging the windows. The drain can be easily cleaned by blowing compressed air up the pipe.

Sour smell when air conditioning running, does this have filter


A/C condenses water out of the air. That water is supposed to drain through a hose that leads from the A/C heater unit. If it gets plugged, the water will stand and eventually molds.
You need to find the drain tube and clear it. If you can find the tube, get some mechanics wire (thinner than a coat hanger), bend the end into an eye, so it will NOT catch on anything, then clean out the tube.

If you can, run the air conditioning for a while to ensure that some water exists. This can help find the tube if it leaks a little, and will definitely help if you do clear the plug, since it will begin to drain when you clear the plug.

Water in the Heater system


On the engine side of the firewall you need to find the small rubber drain hose. it is likely plugged up. dont stick anything hard in there or you can damage stuff inside the heater box.
