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: 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...

I would agree it might be the valve.

Where is the rear expansion vale located on 07 tahoe


{: ) You can find the rear expansion valve at the bottom of the auxiliary hvac module, mounted at level with the floor. The auxilliary hvac is just behind the rear right fender, concealed from the inside by the rear right quartertrim panel. But you can access the expansion valve from underneath the vehicle. A little behind the rear right wheel, look through from below , follow the path of the a/c pipes ending upwards in a rectangular juction. Just be careful with nearby hot surfaces and falling dust. Protect your eyes.

Front AC blows warm and the rear blows cold in my 99 Tahoe


I just worked through a similar issue with my van. The front and rear systems each have their own expansion valve. Chances are the front one is stuck and needs to be replaced. System will have to be evacuated and recharged.
