1991 A/C Evaporator Tube

[-=Jeff=-]

ok.. I see what happened now..

Since the system has to get recharged. wonder if if that could be TIG welded back on..

I was thinking that may be an option as well. The valve screws out just like a tire valve so the heat can be kept from damaging it but the wall is pretty thin. What a weird thing to have happen. Must have been subjected to some side loading on the attached switch in it's lifetime. The car only has 19k miles but it had been updated to modern refrigerant a few years ago.

I mentioned brazing and I recall years ago that it was mentioned by a good friend that you don't TIG R12 aluminum tubes - I did find a similar reference today but didn't note it. Many years ago we had an AC specialty shop and that's where I'd have sent the fellow. They did many specialty projects for myself and others late 70's and early 80's.

I mentioned splice also and it's possible an AC shop would want to eliminate the port as it is now and do their own.

Use the "phone" - then drive the car to the shop - show them what's needed!

OP mentions a refrigerant change so I'd say the technician is maybe a contributor to the issue!

I would tend to agree with the tech contribution especially if this port with the Schrader valve is used for the changeover.

Thanks for the great input. I will let you guys know how this turns out.
