AC lines condensating with AC off?
I don't recall ever seeing this before on my truck (or cars before), but today when picking up my son from school I noticed the large puddle forming under the right front tire infront of the cab. Popped the hood and noticed the AC lines were very cold and condensating like crazy.
Again, I never in my life noticed if ac lines will be cold when the controls are set in the off position?
Any thoughts?

still seems like excessive condensation but they are calling normal on that.

On any setting besides simply Floor or Vent, the A/C system is running. AC, MAX AC, Defrost, Panel/Floor, Floor/Defrost. Thats just the way they are built. The A/C system, during such circumstances as Defrost etc. is designed to remove moisture from the interior so quicker window clearing.
Try it out on a warm day....run the system on any setting besides simply Vent or Floor and crank it over to the cold setting.

Rick, most manufactures use the AC in combination with the defroster to help remove condensation (fogging) from the windshield and side windows. Hence the AC lines being cold. If the outside humidity is high, you will see water dripping. However, if I read your post right, you're saying the selector is in the off position, in which case I don't believe the AC should not be on.
