How to replace evaporator ?

On what? Front or rear? You will have to evacuate the AC system using a recovery machine. Most evaporator cores are labor intensive involving the entire dash assembly of the vehicle to be removed for access/replacement. Not a job for anyone who does not have mechanical experience in Ac repairs

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.

How to replace evaporator core & dryer in 96 ford explorer

This is NOT an easy project, and shouldn't be undertaken under the shade of a tree. You will need a refrigerant evacuation and recovery system (including a vacuum pump), and will need to remove the front casing of the air handler to get to the evaporator core. If the lines to the heater core are in the way, you will need to remove those (necessitating the partial draining of the engine coolant), and possibly removal of the hood so that you can lift the evaporator core from its housing. ARE YOU SURE YOU WANT TO TACKLE THIS?????

Remove the coolant recovery tank.
Disconnect the electrical connectors from the grille mounted lamps if equipped.
Remove the right front headlamp assembly.
Remove the front bumper.
Remove the right wheelhouse panel.
Disconnect the radio antenna cable.
Disconnect the electrical connector for the horn.
Remove the right fender.
Remove the blower motor resistor.
Remove the accumulator.
Remove the evaporator tube.

Our front ac is not working and back is cold in our 1999 GMC suburban, we tried putting freon and it didn't work

Dual zone front/rear ac systems have 2 evaporator cores. And 2 orifice tubes, which are just inline
filters. Either your front evaporator core or orifice tube is probably stopped up.

Sometimes you can get to the evaporator cores without removing them from the vehicle, and clean it.
Evaporator cores do get stopped up sometimes, because the blower motor pulls in air with dust and debris from outside, and the air is cooled when it passes through the evaporator core.

But evaporator cores are a nightmare to replace, you usually have to remove lots of stuff under the dash and lots of stuff under the hood to remove them.
