Question about 2000 Nissan Altima

Evaporator Box in Altima

Hi, you answered my question about the Altima with the water leak, and you told me to take out and clean the evaporator box. Can you give me any more information on how to do that? I have tried to remove what looks to be some sort of condensation resevoir that is above the glove box (I removed the glove box to access it) and though I've removed every bolt in sight I still can't move this thing! I can't figure out how to remove it. It's frustrating because it seems like a simple problem with a frustratingly difficult solution.

Also, do you know where I might get another ECU that's compatible with my second generation Altima? Do I have to EXACTLY match the numbers on my computer, or can I just come close?

You cant remove it because there are 2 pipes attached to it under the hood. You actually need to recover the R134 out of the A/C system and undo those 2 pipes to get it out. There may by some more screws that hold it in. See if your Altima has a small opening, that may be covered (incabin filter hole) Some 2000 models started coming out with incabin filters and that's how they get replaced. It would be visible since you have the glove box out. You will see a small cover 1 inch wide and about 6-7 inches long. If you don't see anything like that, than you don't have the slot for the filter. If you have the opening, (right above the blower motor) remove the cover and look in the slot. You will see the evaporator and inside of the box and what is in there aka pine needels etc.
As far as the ECM goes, those are car specific and can not be mixed. You need the ECM with the same part number as the one that came with the car originally. Good luck.

Where is expansion valve located


The Expansion valve is located in the evaporator box

On this year Nissan it's not to bad of a job. The dash doesn't need to be removed like the newer cars.

  1. To replace the expansion valve, you will need to discharge the AC system. Remove the two AC lines from the evaporator.
  2. Then you will need to remove the glove box
  3. Then you will need to unbolt the evaporator box
  4. Tip it back and remove.
  5. Once you have the evaporator box removed, then you can replace the expansion valve. I would also clean the evaporator box as well since you will have it removed.

If you are talking about the evaporator for the ac, the component would need to be replaced.

Leaking on the right side under the car they told me it might be the evaporator but I don't know where that is in my car I have a 1997 Ford Expedition, I don't even know what it looks like


The evaporator is located in the heater box, it is the AC's equivalent of a heater core. Water is a NORMAL by product of refrigeration, and the clear water must leak out to the ground.

My 96 Suburban A/C does not cool properly. Been told evaporator need cleaning. Would that cause the air volume to decrease when turning on the A/C?


sounds valid to me(depending on the setup of the HVAC box,it may only blow air through the evaporator when in the "AC" positions)

2005 MITSUBISHI ECLIPSE AIR CONDTIONER IS LEAKING WATER ON FLOOR BOARD AND NO WATER UNDERNEATH ON GROUND


Sounds like a plugged evaporator drain. Pretty common on these cars as many did not have cabin filters.

Ideally you should pull the evaporator box and clean it out, but for a quick fix you can shoot compressed air into the drain tube to clear the blockage.

The drain tube is in the engine bay, on the firewall just above the steering rack, nearer the drivers side. You will need to pull up on the firewall mat/fabric to see it.

You probably have a clogged drain for the evaporator. The evaporator would have to be removed youmay have to have a professional perform this.

Water leak inside the car


Whats causing this is that the drain hose for the evaporator is clogged and overflowing into the car. what has to be done is get under the car and find the drain hose, which is going to be on the passengers side of the car by the firewall, and get either compressed air and blow into the hose to try to free the blockage

It sounds like you may have a blocked drain in the evaporator box. This is where the heater core and evaporator are located.

If you look under the vehicle about where the heater is located, you should see a small tube sticking down ( plastic or rubber ) this should be he drain.

You can squeese the tube open and see if it will drain, If not it may be clogged up with dirt and debris that may require the box to be removed and cleaned.

Check the air inlet, usually located in front of the windsheild, just under the wipers for debris. Keep this area clear. If it has a lot of leaves or other things around it, it can cause water to build up and flood the evaporator box, as well as get down inside.

You may need to take this to a shop that can put it on a lift and get at the drain from the underside, they may be able to clear it without too much troble
