KingDoc1 - you are exactly right: 134a was NOT meant for my car. I agree 100% that the system should be R12. I checked out FleaBay & found serveral sources for R12, plus I have a friend in the HVAC business who could purchase it for me.

Ken300D - thanks for the advice & how-to instructions. My HVAC buddy pretty much described the same process when we discussed my situation.

So, you guys have convinced me to go back to R12 - so that's what I will do.

Many Thanks!!! This forum ROCKS!!
