The long story began here:

So after being forced to admit that I had allowed a shop to put Freeze12 in last year and now faced with a hot summer and a system that was barely cooling the air, I proposed the following:
Quote:
Ok, here is the plan:
1. remove remaining old freeze12;
2. replace expansion valve and consider replacing hoses; repair shrader valve core on low side; replace E.T.R. switch; replace 0-rings and lubricate with Nylog assembly lube;
2. flush entire system with "mineral spirits first and then follow that up with regular a/c system flush to get out the residue" and then "blow, blow, blow" (LarryBible--04/14/2005)
3. vacuum test; I don't have the equipment to pressure test with dry nitrogen and do not have an electronic leak detector; and
4. Charge with PROPANE -- sorry, couldn't resist that -- charge with correct amount of R-12. I don't need a 30lb supply -- is there a better source for small cans other than e-bay?
Now all I need is a few days off work.

I never got the few days off and I suffered along and even resorted to driving the Durango (13 mpg sucks) some. Finally, the compressor developed a massive leak around the outer seals. So I did all of the above and completed the vacuum test 9 days ago. But the R12 I had bought on E-bay did not arrive until today. The system still held the same vacuum it held 9 days ago. So I charged up the system with 2.9 lbs of R12. BTW it was 95 F according to the Durango temp guage this afternoon when I shot the photo below.
