no air condition

[chrispugs1967]

ok so i had a leaking line i changed it and now i have no cold air. i had the system charged and the line going into ther coil is cold but the return line isnt. the air in the cab is comming out at 86 degrees. Im wondering if the heater control valve may be busted. i did check the blend door actuator which does work but i guess maybe it can still not close all the way to prevent hot air from entering the cab. I'm not totally sure how the whole system works and i hope my thoughts are right here, any help would be helpfull.

I guess I'd need to diag that one on pressures..
sounds like it might be undercharged (or another leak)
but you could also have a plugged expansion tube (orifice tube)

but you could also have a plugged expansion tube (orifice tube)

IMHO x2

We had a GMC mini van a few years back w/ front & rear AC. One day both the f & r quit blowing cold. They somehow figured the rear orifice tube was bad and crimped the tubing to the rear part of the system. (The cost of repair was insane.)

Once they did that, the front started working quite well.

Thanks for the advise I'll check the orifice tube tomorrow, it is holding pressure so i cant see it being another leak. i'll let you know how i make out. thanks again

...make sure the plug on the compressor is good and secured. I went 2 weeks with no ac becuase of that.
