Got the A/C working again! I have a leak somewhere, and at $250 a pop to recharge the R12, I was cooling my car via a 4x65 system (windows down on the freeway!). Bought a R134a conversion kit from Kragen, and swapped it out. $50 later, my A/C is nice and cold again. And this stuff's only $7/lb, and you don't need a licence to buy it! If anyone needs any info, contact me. I'm happy.
