Re: A/C THX (expansion valve)

I will be interested in seeing this as well. I had been reading and decided they can get sticky if "stop leak" was used and any trash can get in there as well. I dont think mine had ever been replaced so I did. It was only around 15 bucks new so I figured it was worth the shot.
Just a little more info years ago somebody had given my a POA delete so I am using that as well. Still wish I had the POA but what I have is working but I am still tweaking on the charge pressures.
Good luck
Dave
