Yes, that's it. The arm should move from about 4 o clock position to about 2 o clock as it goes from open to closed.

If your AC isn't cold, it could be that you're low on refrigerant.

In my case, it does go cold when it's properly on, but I wouldn't call it the "Siberian Winter" that several people here have said it should be. Certainly chilled beyond ambient and enough to keep me comfortable, mind.

I think I can get my vent temperatures to 3 degrees, so it's cold.

If it helps my system works well, except on cold, a bit of cold air blows on my feet, much less than it did before I found a disconnected vac hose, it used to turn my feet in to ice cubes.
So if you want some temp readings let me know. PO spent 4k in a dark room getting this system to work, why a dark room, no idea.
But if work great. I make sure to run it every couple of weeks... no drying of seals. Paranoid yes..Fingers cross yes... Pray yes...long live the cold air.
Oh and the system a new heater valve... LOL

3 to 5 is my aim point for all my cars. I don't want it below freezing, otherwise the moisture in the car can turn to ice in the evaporator and block the airflow, but I want it just above freezing. AC is a thing I'm fussy about, I want it to work well in all my cars, so I bought the tools to do it myself. I've saved thousands by doing it myself on various cars and friends cars over the years.

Angry Old thread,

Hey guys I,m having the same issues its a few years later now, and i,m wondering if this issue was ever solved, I am running a chevy 350 with a clutch fan, when i start the car you can actually see the sweat on the a/c line going to the evap coil, evap temp is about 38 with fresh intake dampers closed on compartment circulation open, about min into it i cant get the temp below, 67, and no more sweating, New compressor, new dryer, new txv valve. i,m going to try the water on the condenser test tomorrow, my head pressure is around 200 but climes to 250 that tells me i,m having an issue with the condenser not moving enough air through it, I did the thermometer test across the condenser and its a steady 150-160 through 90% of the coil. Any help or input is appreciated .. P.S. my heater core is also bypassed. for no heat. just like the other Gentleman.
Thanks
