fj60 A/C adjusting rpm problem (1 Viewer)

[4runner2FJ60]

I just found the loud hissing noise I have been trouble shooting, it is coming from the ac idle up pot. if I remove the manifold hose to the vsv it stops....I either have a bad vsv or hoses are switched. Are there new vsv(s) available to purchase? Part numbers?
Thanks

The idle up VSV is easy to test. See Post #16 on Page 1.

Jim, It was coming from the AC idle up pot on the carb!

Will that test work is the ac is not functional? I did the 12v test. Swapped hoses and the hiss is gone now.
