Mr. LEG

I have a 2007 and have had the AC expansion valve changed twice due to a hissing sound from the right side of the car.

They said a bulletin was out for it.

But both times they were changed it still hissed after the fix.

anyone have the same issue or have any advice for me?

I need to get this fixed ASAP cause my warranty expires at the end of this month..

thanks for any input

my06 ac hisses and howls alot..is it the same problem its pretty annoying

Mr. LEG

mine does it only when AC is on and between 3000-4500RPM.
It hisses almost with a metal rattle.
Is that similar to what you have?
