SOURCE: expansion valve location

raven 1g: Your car doesn't use an expansion valve. It uses a fixed orifice tube which is located in the smaller of the two A/C lines, just before they enter the cabin area of the car.
Just disconnect the line and pull the orifice tube out of the line. Be careful not to break off anything and leave it in the line.

SOURCE: Where is the expansion valve located on a 98 Grand Am 3.1?

Grand Am has an expansion valve. Link below has part number and picture of what you are looking for.
http://www.discountacparts.com/addtocart~year~1998~make~Pontiac~model~Grand_AM~descript~A-C_Compressor~part~60-40281.asp

Unfortunately, I do not know precisely. But for the most part auto a/c's are all the same. Below I will describe how to find it. I have also included a aguide to determine system operability that may or may not be helpful. Just trace the system with flow path described below the valve has to be between condensor and evaporator.

Reminder the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer2_bing.gif back to the compressor suction.

Below is a guide to troubleshoot and check system function. This can be done by most folks.

Look at the front of the ac compressor and have someone turn on the ac from inside the car. The front of the pulley(clutch) will spin when turned on.

If it does not spin, the low pressure switch (LPS) is not satisfied. Meaning there is not enough freon in the system to operate the system. Means low freon capicity because of a leak.

The LPS can be jumpered to cause the compressor to run (clutch to engaged) which will draw the freon in the system.

The LPS is usually a two wire sensor on the suction of the compressor. (between evaporator and compressor) Unplug the sensor and install a jumper, this will engage the clutch. Connect a new can of freon
and fill to system capacity.

The capacity of the ac system will be on a label under the hood, do not overfill. Probably about 2 lbs. Local parts stores (Auto Zone and Advance) will have freon with stop leak. This may help the leak. They also make a freon with a UV dye. I always add a single can with dye so that if stop leak does not work I can find the leak in the future.

The system should be filled until suction pressure is about 30 to 38 psi..

SOURCE: Can't find rear a/c expansion valve, where is it

I am in the process of doing the same procedure on my 2001 durango 5.9... condensor, compressor, accumulator, followed by both front and rear expansion valves. I pulled the rear passenger side trim off after following the pipes to the back. It looks like the expansion vale is the first component hooked to the pipes just as they come through the body into the cabin. It appears to be wrapped in a black sticky mat... I did not unwrap yet so it may not be... What are your failure symptoms? I have a slow leak and a blockage inside the system to where it cannot be fully charged without releasing pressure from the rear of the compressor. I sure hope its not in the evaporator core...

How do i perform an expansion valve removal


Are you adapting the unit for a different refrigerant? Expansion valves are usually located on the line going to the evaporator from compressor. Could be right by the evaporator or a tad further back.
Make sure that you use the correct size so the right amount of "flashing" is created for the system.

Where is expansion valve located on 2004 mazda 3


That valve is located just in front of the evaporator. You can look for the location that the high side connection uses to go through the firewall and it is either there or just on the other side in the plenum. However, if you replace it, you are looking at a long complicated process that should not be undertaken as a do it yourself project because it requires tools and training that you cannot short cut.
