Is A/C without R12 dead
A dealer and good mechanic can’t get cold air. Cool air, but not cold air.
What am doing wrong
What do you mean by this? R12 hasn’t been used of over 2 decades.
Why not? Are they incompetent? Or did they tell something is still wrong?
For starters, your post is very unclear on what the problem is, the condition of your car - miles, history anything, really, except year, what you’ve done to try to fix the problem or why you’d ask about R12. A little info from you and maybe we could assist.
I doubt you have R12…it was discontinued a long time ago…but if you have no refrigerant, you will have no air conditioning
