When i got my excursion it was wrecked, the first time i went to have the ac charged it had a major leak, at the rear expander valve, on of the lines was completeley disconnected, after reconnecting it i had no more leaks... then the ac guy put too much freon in and it never got cold in the rear only the front... later that night after it had cooled off, i tried to run the ac again, and it was making a horrible maoning noise, and the compressor was blowing off.... so he overcharged it. I thought the compressor was bad, so i bought a brand new visteon compressor on ebay for $150 hooked it up and it blew really cold in the front, but the rear does not get cold. I think someone swapped out the expander valve when it was parked ina wrecking yard somewhere, because the front seat were also missing, visors, it had pretty much been pliiaged befoe I got it, so my guess is the expander valve was swapped from another (no working unit) whew long story! Is the heat expander valve the same valve I am talking about?

 

I know this is an old post but want to help those looking for a solution without paying top dollar from the dealership...

And another one that is on Amazon and Ebay that looks like this:

Called a Line Splice Repair Kit

 

Yea, it's over $1,000. just to replace that one line that goes all the way to the front and now only comes in 2 pieces. I did a "how-to" on how to use that splice above ^.

 

I had the exact same issue, no rear a/c.

I did oodles of research and learned that the stock a/c lines are crap. Ford has done nothing to upgrade them, as this is the only vehicle that uses these particular lines. The E-350 uses a different set.

From what I learned, the lines will fail. It's just a matter of time. In particular, they get little holes in them and lose efficiency before failing altogether.

I went with aftermarket lines, and I'm glad for it. The a/c works vey well now.

I wouldn't disconnect them, like option 4 of the OP. That just means the front a/c will work harder to keep that huge fishbowl cooled. The air flows throughout the vehicle, so you'll just be over taxing the a/c system by only having the front a/c working.

 

It depends if you want to cool the whole thing or not, I have never turned the back one on in 4 years and don't even know if it works....not overtaxed. My line near the back wheel did have a pinhole in it so the front ac didn't work.....all good now.

 

Wow... My 5 year old thread comes back to life!

To give a wrap up, here's what I did..... Nothing... LOL

The diagnosis wasn't as bad as it turned out. I had A/C for the summer... but by spring it needed a recharge. A can or two of refrigerant and I was cool again.

5 years and over 100k miles later... I still have the truck, but since I went from a car allowance with a fuel card to a company car, it gets used more occasionally these days and I haven't gotten concerned with the A/C.

Another project (70 Chrysler 300 convertible) is getting an updated A/C system and I'm going to buy a vacuum pump and do this myself. I'll get the Ex system up and running again when I get to it.

 

I think this topic will always be a good one.
Today I called Auto Cooling Solutions and they are flirting with making lines for the excursion. IMO they should because nobody else does!
I am just ordering a 18' "repair hose kit" and eliminating the original aluminum line. It had countless holes in the front and one next to the rear hanger.
They also informed me they have the block offs in stock too. Not a fan of only having front AC... Why half *** it? I haven't half ***'d any other part of my Excursion, why would I start now?

 

Hi Joe

This is a shot and a prayer, I have a 2004 E350 passenger conversion van that was originally a commuter van for enterprise. It has 125,000 miles on it. My family only puts about 2000 miles on it per year, trips, evts, etc.
With That the rear air is not working at all.
A local very reputable garage that does air work said he would have a lot of problems with the "rotted" rear air lines needing allreplaced.
When i read this thread it is very similar to what you describe.
Due to the fact that we do not use the van that much I cannot justify thousands of dollars to fix .
Can you give any advice.
I live in Johnstown PA, if you are willing I would pay you to fix it, and time would not be an issue you could have the van for a long time if it got fixed correctly and less expensive (i can't even get a good quote, the garage said thousands).
In other threads I have read of individuals fabricating a sheet metal tray, insulating it with spray liner, drilling seeping holes, using rubber tubing and fixing it that way. That is way above my ability or the time I have.
Please help!

Joe

 

hey all.
working on 1993 e150 clubwagon .
mission objective:restoring the heating and ac to the rear of the clubwagon.
heating and ac lines are rotted away.
planing on fabricating new lines using appropriate rubber based hoses.
i assume i use hoses with the same size inside diameter for both heating and ac lines.
please jump in with some advice

 

Something tells me that long runs of rubber hose for the Freon, especially the high pressure liquid line is not advisable.
