I need some rear a/c help.
 
I recently added a Vintage Air system to my burb. I replaced both lines that ran to the rear ac unit, flushed the rear evap, and replaced the expansion valve on it.

The front cools as it is supposed to. The back has never cooled. I thought the expansion valve was defective so i replaced it. No such luck. I am not getting flow to the back.

I need a picture of the expansion valve installed and a picture of the capillary probe installed. I have a friend that thinks I have the expansion valve backwards. I took it apart and slept before putting it back together....possible but not likely.

Thanks
Darryl

well it was likely... in my defense there was no "flow arrow" on the expansion valve. The same thing happened to me on my electric fuel pump (again no arrow). I seem to be developing a pattern.

I don't know if this will help. And if your system is full and flow is corect you might just have a bad valve. I have gone around and around thinking that because somthing is new it must be good! :dohh:
