How can I replace A/C expansion valve? - 1999 Nissan Pathfinder

Hi,It is not to difficult to remove or replace the expansion value for your Honda cars. Only you have to do to replace or remove the components. You have to disconnect the two lines to the evaporator from the engine bay, then you will have to remove the evaporator unit from under the passenger's dash. Then you take apart the evaporator to get to the expansion valve.
Here's I have also attached the video of expansion valve replacement of your Honda Accord.

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.

1.) Discharge air conditioning.
2.) Remove dashboard
3.) Replace expansion valve.

ive never seen an expansion valve in an rx8 go.....
usually its the climate control head. The blend knob stops working...

Follow the a/c lines to the firewall. The part they are attached to is the expansion valve. Once the a/c system is evacuated the lines can be removed from the expansion valve. The expansion valve can then be removed from the EVAP core.

Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

I think It costs $45 plus to replace a expansion valve. Here you can find more quality expansive

Does the compressor run?
Low side could be high without a running compressor.

A running compressor?
The expansion valve itself is about $50 and bolts in.
You will have to remove the 134a gas before installing a replacement expansion valve and vacuum the system before recharging.

It is attached to the back wall of evaporator. You have to remove the glove compartment, blower unit and evaporator to get access to the expansion valve.
