I think it is the Expansion Valve ?

jameshobbs on Wed August 29, 2007 4:43 PM User is offline

Year: 1997
Make: toyota
Model: avloin
Engine Size: 4 cyl
Refrigerant Type: 134
Ambient Temp: 85
Pressure Low: 10-20
Pressure High: 200


Hi guys my friends car A/C is blowing 60-70 degree out of the vents .It was pulled down and some dye put in then charged with the right amount of 134. The low side runs 20-24 and then drops to 10-12 like the Expansion Valve is sucking for dear life then eases back to 20-24. It looks like the Expansion Valve is inside the car if you think it is the Expansion Valve how much of the dash do I have to pull to get to it? Has anyone done one in a while? is it a bear?
Thanks for your time , Randy

Having the expansion valve inside the car means this is probably a model with a readily removable evaporator case. The case is removed as a unit thru the hole left after removing the glove compartment. No need to take the whole dash apart.

Does it sound like the Expansion Valve to you ? I guess there will be bolts holding it to the fire wall and cables & wires ?

Thanks for your time , Randy

Could very well be. Also see if the outlet pipe of the drier runs cold, that means there's a restriction in the drier. Make sure no one has put sealer in it. If there's sealer you really don't want to touch it.
