another ac ?, advice needed
so since summer is coming, I, like everyone else, want my ac working well. vehicle in question is a 1990 truck. i have had it for 3 years and never touched the ac as it has always worked well until now. I notice the compressor does not cycle off as it should, or almost at all. Is it normal to lose a charge slowly? It is still working, just not nearly as well as it used to. How should I go about servicing this? It is still R12, and god knows when the last time it was serviced was. Am I better off just converting to 134A? If so, EXACTLY what is involved in this? I have also heard about something called "Freeze 12" what is the deal with that? Lots of ?'s i know, but thanks for any help.

Alot of people will tell you to convert it but since it still cools some i would just add a can of 12 to it.. I know of several cars that have to have a can added every spring and they work fine all summer.. thats what i'd do

How much does a can of R-12 cost? I converted to R-134 but I also did have a R-134 compressor to swap on. It's not as hard to convert to R-134 as it was once thought when the R-134 first came out. The main thing is to remove as much R-12 oil from the system as possible and use a compatable R-134 oil when you recharge the system.
