My air conditioning nightmare.2000 Grand caravan

Dont scare me about the front evap. Thats a big job.
I did find a leak underneath,where the tubes go into the rear evap.
The smaller tube had a pinhole,enough that I could wipe it away every minute or so. Not much there to be sure,but I assume it's the low pressure tube as its warm. I was desparate to fix it.I've spent ridiculous sums on this in the last 2 days.

So I scuffed the tube and used epoxy putty. Now
im praying that it holds.


The smaller line is always the high side while the larger would be, you guessed it, the low side......:cheers:
