I'm working on a '95 Suburban. The initial problems were the front evap was leaking and the aluminum lines to the rear evap were leaking.
As such, I replaced the lines from the front to the rear with new OEM lines. In the process you need to take the lines off the rear evaporator. The problem is that they are located near the rear wheel wells and as such they see a LOT of corrosion. Electrolysis is also a major issue as the nut is steel and the fitting is aluminum....
Anyway, I got one of the lines to the evap off without twisting the evap. The second one however was so corroded that it could not possibly come off. It twisted off and now the customer needs a rear evap. That was more/less OK but when I got into the evap case I found out that the line that twisted is actually an intermidary line. Of course, the new evap does not come with that line....
So now I'm stuck. I'm not able to call GM up here (it's a holiday) to actually see if they still make that short intermediary line. If that line is not available then the only course of action would be to have one made up - or the customer doesn't get rear A/C (and that's not acceptable to him).
The question is, can anyone actually make an aluminum line complete with the flare (for lack of a better word) that the o-ring backs up against?
Has anyone run into this before with a rear air suburban (I would think it's really common) ?

I have. I was able to use used parts but only one junkyard was able to get that stuff apart. The rest were just like you stated. Pretty much impossible to get apart. I remember the line that you are in reference to, it comes apart at the expansion valve. You should be able to get that part from GM i would think.

Thanks torque395 - it is the one you mentioned. My cousin was over and he also felt the chance of availability was pretty good because he figured that body style was probably used up to '98 or so. I'll call in on Thursday to see what the scoop is. :-)
BTW, it's just nice to hear from someone else who knows how rare it is for those things to come apart - thanks for that too! :-)
Best & Thanks;
