Car AC not blowing cold air
 
i checked under hood after no cold air blowing from vents.....i found 2 metal pipes going toward the fire wall, a small one with a cap and a larger one......the smaller pipe was cold and condensation was forming on the pipe, the larger pipe was warm,,,,from what i have read it should be the other way around.....what might cause this?

dryer is restricted... check out www.aircondition.com

Definitely sounds like a restriction in the high side (small line). Have you had work done or an accident hit a small animal? A kink in the line will cause a psi drop also. If all looks good I would go with the dryer if its an expansion valve system. If its an orifice system. The dryer is in the low side line and shouldn't cause that issue.

AC is not something you can just guess at. Is the compressor running?? What are the pressures??Before you do anything, find this out. Would greatly help. Also, what kind of car is it??
