Where is expansion valve located

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.

Remove the coolant recovery tank.
Disconnect the electrical connectors from the grille mounted lamps if equipped.
Remove the right front headlamp assembly.

This is ''pops'' moore again!trying to save a $ You helped me before on the firing order.went to a/c guy.he tested system,said evaporator was bad and needed to be changed.his est.was my first born and a...

I assume he used a leak tester and found a leak in the evap which is inside the plenum housing. Need to remove the plenum to get access to the evap. big job. If you are technical, you could remove the plenum assembly and let him replace the evap & then let you out the plenum back in. Then take back to have him evacuate and recharge system.

The following is a general removal procedure of A/C evaporator core. The evaporator is removed differently from different vehicles.
For example, a 1994 Ford Taurus/Mercury Sable instructs you to, "Using a hot knife, cut the top of the air conditioning evaporator housing between the raised outline."

Use a hacksaw or a hot knife to cut the case. Reprinted with the permission of Ford Motor Company.
But a 1993 Ford Probe manual says to simply remove the blower motor and assembly screws before separating the case halves and removing the evaporator.

The following procedure assumes that access to the evaporator has been determined.
  • Recover the refrigerant.
  • Drain the radiator if the heater hose(s) has to be removed to gain access.
  • Remove the heater hose(s), if necessary.
  • Remove any wiring harness, heat shields, brackets, covers, and braces that may restrict access to the evaporator core.
  • Remove the liquid line at the thermostatic expansion valve (TXV) or fixed orifice tube (FOT).
  • Remove the suction line at the evaporator or accumulator outlet.
  • Gain access to the evaporator core as outlined in the service manual.
  • Lift the evaporator from the vehicle.
  • Drain the oil from the evaporator into a calibrated cup.
  • For replacement, reverse the preceding procedure. First, replace the oil with the same amount and type you previously drained.
