1999 Solara Expansion Valve

Solar4 on Sun April 25, 2010 6:52 PM User is offline

I am looking for the best way to access the valve to replace it. Do I need to go through the glove box and remove the blower assy (from the right)? Or do I need to pull the dash out (access from above)? I can see the HP & LP lines where they come through the right side of the firewall. They immediately make a 90 turn following the upper backside of the firewall over towards the center of the car.

Any tips would be greatly appreciated!

Evaporator case needs to come out. Expansion block is inside the case.

How do I remove the evaporator case? Do I first remove the blower assy for access? Does the evaporator case separate from the rest of the HVAC unit in the center console or does it need to come out as a complete unit?

Remove left floor air duct. Remove expansion valve. Remove grommet from evaporator.
Using a knife, cut off packing. Split evaporator case. Remove evaporator and water seal. Release 4 clips and remove plate from evaporator. To install, reverse removal procedure. If installing a new evaporator, add 1.4-1.7 ounces of refrigerant oil. Evacuate, recharge and leak test A/C system.

If you need a more detailed procedure I suggest using either Mitchell or AllData.

Ok, thanks for the responses!
For anyone else's future reference: I was able to get to it via removing the blower and associated ductwork behind the glove box. It was sitting on top of the evaporator box and installed with 2 bolts requiring a 5mm allen wrench.
