2005 Chrysler t&c, 3.3L 55k. Dealer wants $1000 to replace rear refrig. lines. I looked and the leak is at the connector where lines enter cabin. Is there a way to fix that connection or just plug the rear lines?
Thanks for any help.

It depends on what's leaking. If it's just an o ring, then the parts are cheap & you are looking at mostly labor. If the lines themselves are leaking then, they would need to be replaced to do it correctly. There are no kits I'm aware of to bypass rear a/c. Those lines tee off the front ones and not easily bypassed..........

Re - Plugging off a rear evaporator: It can be done but no kit known by me. If you are willing to sacrifice the lines I'm told they can be cut, bent, hammered and welded "heliarched (I hope spell check catches that word for alum welding) and charge carefully. It may not be the same as what's listed for a front only system.
Side topic but my opinion: The compressor - one - can only put out so much and rear is just splitting the same available BTUs. It's still helps in extremes as the far back of vans is hard to get much cooling to from the front only.
They have power port/cig lighter fans that can help get cabin temps even. If there are passengers in a third row it will stay a tad warm back there in extremes. Blow cool air high as it falls readilly.
If that is attempted, do seal off the cut off lines to rear as well. PAG oils turn acidic when exposed to air and the moisture in it and would likely take out rear evap and other components if left open too long and you changed your mind,

Thanks for the help. I learned that the father of my son's friend capped the lines in same situation. I'll have to ask how he did it.

Haven't done it yet and not skilled at making up plugs out of end lines as said. I only know that it can be done as said,

I maintain a fleet of chrysler minivans used as taxis, so I've seen why they are quoting you so much. Your body style has an intake manifold that blocks view of the lines through the hood. They like to use a one piece line from compressor to rear of van with a connection at the orifice valve on the firewall. If you had lines from the same model without rear air it would bolt up and route identical to the factory unit. If you use a set from a salvage yard (which I don't recommend due to failure rates) and replace the O-rings at the compressor and valve it should hold provided there is no problem with your front air system. Last I checked these still use a 5-part system and not an accumulator system so a new receiver drier will be in order after exposure to humidity. When R-134a is in contact with moisture it creates hydrofluoeric acid. Vacuum alone cannot rid the whole system of moisture. The drier should be replaced. Take off the grill and it should be sitting in the line bolted to the condenser at the front of the van. With the difficult access, you can save a lot of time by just buying an upper intake gasket and pulling the upper intake out of your way. Remember to stuff the plenum tubes of the engines with rags to prevent foreign objects from finding a way down there and wreaking havoc on your wallet any more than the a/c has.
