Question about 1999 Nissan Quest

1 Answer

Replacing Nissan Quest AC

My compressor blew and in the process of replacing the compressor accumulator and valve. Came accross a few things in the process.

How does the accumlator hose disconect from the side next to the firewall. It looks like it should slide out, but I have twisted and pulled at it without success. I don't want to pull to hard and risk breaking a line.
Also do you know how much compressor oil it will take. Under the hood it says 325 cc. That just seems like a lot.

I thought I would have seen the orifice tube, but haven't. Do you know where I should expect to find it in order to replace it?

Orifice tube is in the high pressure liquid line going into evaporator. You will see a small crimp in the line.

It sounds like you've done just about everything except to check if there is a bad or intermittent wire causing this or perhaps your low-pressure safety cutout switch is possible going bad causing the compressor to kick on and off?

Replace AC Compressor, Accumulator, Orifice Tube, and Hose Assembly


Made a video on how to change the AC Compressor, Accumulator, Orifice Tube, and Hose Assembly on my 2003 Ford Focus 2.0L SOHC SPI. Symptoms started off as blowing hot air at idle and then it just blew hot air all the time and Firestone told me it had not compression and needed the compressor replaced.

A mechanic would check the system with a set of pressure gauges. If the compressor is running, the low side would read around 30psi and the high side would be around 250psi. That is how you know if the system is full of freon or not.
You may have to get a professional diagnosis to proceed. If you replace the compressor, the accumulator needs to be replaced and a vac pump is used to pull all of the air out before the freon is added.

A/c condenser leaks need directions to replace


First things first.

Make certain you have all the parts and tools required before you begin...
You will need a torque wrench to properly replace the unit.

Having said this and not knowing which model or year your Hyundai vehicle is. I will say that if your vehicle is not already running on the R134 refrigerant, this would be a good time to make that switch over and upgrade.

If this is what you are considering, the Air Drier/Accumulator would also need to be replaced at this time. This is the cannister usually nearest the firewall with the two A/C hoses/pipes coming from it.

(A/C Compressor - Drier Accumulator - New refrigerant)

You should completely disconnect your battery.

Removing the A/C Compressor will vary in difficulty depending on it's location.

Some A/C compressors are located on the top of the engine, or just off the side and are really easy to exchange. While others are located in more difficult to reach areas, like underneath.

Depending on where your's is located, you may find it easier to first disconnect the hoses on the back as well as the bracket supporting the rear. Then remove the bolts from the from bolt tabs and proceed to manuever it away, as best as possible..

Same process for the old Drier/Accumulator cannister. Dosconnect wire connector, unbolt hoses and make note of it's position, to help with installing the new cannister properly.

(*** IMPORTANT NOTE***)
Some A/C compressors have a SWITCH. This is generally located on the rear head of the A/C compressor and looks more like a cap that is screwed onto the switch cavity plug. You may note this once you remove your old compressor. Remove that and keep, you will (most likely) need it to use on the new compressor.

I mention this because new compressors rarely come with a new switch and all too often people will install their new A/C compressor without swaping that switch from the old to new compressor... In which case, it will prevent the compressor clutch from actually engaging. Hence the result would be no cold air being detected, and a process of chasing fuses and relays begins in order to try and find out what it is and why it is not working...

(***Hopefully you have read and noted the above NOTE, YES, it is that Important***)

There will most likely be instructions in the box with your replacment compressor and I am assuming that you are replacing with new as opposed to used parts.

Installing the new compressor is in the reverse order. Once everything is tightened up and bolted back together.

As you begin filling with the new refrigerant, take note of any air leak or hissing sounds right away. If any noted, make proper adjustments prefore proceeding.

Hopefully you will have found this useful

Good Luck and Happy Motoring

The Air conditioning compressor will only run for short periods


You said the freon was checked then the problem may be the pressure switch located on the accumulator. It may be faulty.

Blew high pressure switch off compressor replaced that. wont take but 1 can freon high pressure


If you have not put too much oil and refrigerant in the system, then you have a restriction in front of the compressor. Most likely a plugged orifice tube, but possibly the receiver/dryer/accumulator. Both will have to be replaced and the system flushed. The orifice tube requires special tools and skills and unfortunately, it would probably be better to take this job to a professional at this point.

AC compressor blows fuses when it goes to kick on.


As a mechanic I NEVER put that JUNK in ANY system, they clog up A/C compressor's and every thing elese. (You might have to replace most of the components in your vehicle now. ie condenser, evaporator, compressor, receiver/dryer (accumulator), orifice tube (thermo expansion valve) and you may be able to flush out the lines.
