My wife has a 2012 Grand Caravan Crew that is modified for wheelchair use. The floor was cut and dropped 14".

To do this, I am sure they needed to modify the lines going to the rear a/c unit (van has rear air).

The a/c failed yesterday and with a UV light I traced the failure to a hole in the high pressure extension tube just after the coupling to the solid part of the flex line going to the front of the van.

Problem, when I look up replacement parts, they are showing the flex line and this extension tube as one part ... no coupling.

So, I am trying to find out if these extension tubes were stock from the factory (separate from the flex lines running to the front of the van) or where the factory lines one piece and the ones one the van now are custom (or off an earlier model or ???).

Thanks ..... Mike
