If this has been covered before, don't give me grief! I didn't even know what to search for on this one.

So, the picture below, this is on the passenger side coming right out of the firewall. It was not hooked up to anything when I got the truck (as far as I can tell from my 'pre-tear down' pictures) I tried the engine cooling system, not it. I can't work out if it's for the AC system, Heater? some sort of breather? But the pipe is ridged at the tip so something is supposed to connect to it...? Come on guys.. help me out with this a little more than you all helped with my who's who of the ADD VSV's !

 

looks like part of the a/c to me...did someone pull the condensor etc from the front of the truck too?

 

No siree.. seems like all of the AC components are there. But I haven't thoroughly looked at the AC system. TO answer your questions, the condenser is there.

 

If it's what I'm thinking of it's the A/C drain
Should connect to the black box containing the A/C core, rad thingy inside the cab.

 

AC condensation drain, Don't pull on it or it may come loose and drain into the cab.

 

Good stuff. thanks guys!
