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...

P1250 and P1569 codes. Engine still running rough after complete tuneup. What should I check now. Any Mcguyver fixes? 2002 Mazda Protege5


1250 is the fuel pressure regulator and 1569 is variable timing control solenoid. Both will cause rough running. I would check the regulator out first.

Where is the AC expansion valve on a 2002 thunderbird


expansion valves are located at the inlet to the evaporator of the ac under dash
it is used to allow the liquid freon to expand as gas and so operate the evaporator
unless you have a problem of contamination in the ac system ( air / water) there is seldom a problem with TX valves
it is controlled by the thermostat so that is most likely where the problem will be

A/c expansion valve


ac expansion valve (TX ) valve is located on the inlet side of the evaporator under the dash
it is what controls the rate at which liquid is allowed to escape to turn to gas and so cause the cooling process.
they are known to block at the orifice as it is very small or the thermostat will not control the liquid flow to the tx valve

Where is the expansion valve located? The air conditioner is blowing hot air in front and rear units. I did put two cans of fr-ion.


Is the system full of freon ?
The rear ac uses an expansion valve, and the front ac uses an orifice tube. One system can work independently of the other.

Where is the EGR valve on a mazda protege 5


I own a 2002 Mazda Protege5 with the FS2.0 Motor. The EGR Valve is located below the throttle-body. You must take off the Intake tube to get a good view of it. To replace it I think you might have to take off the throttle-body, but I'm not sure about that...(yet)


NOTE: Mazda put out a technical note stating that "if your car has sat for a long time, the egr valve could be damaged by moisture (rain) and will need to be replaced". My 2002 Protege sat for 3 weeks and the rain caused this exact issue and had to be replaced. How did I know? The engine light came on (after never coming on) and the car had an extremely rough idle. Total cost was ~$400 (ouch).

Location of air conditioner expansion valve.I need to check it for possible problems such as being plugged.


Expansion valves dont normally get plugged. If anything gets plugged it would be the dryer. It has desicant in it to remove moisture from the system.
