Not too late
You are not too late. All I have changed so far is the drier bottle and o-rings for it. I have not touched the expansion valve yet and dont plan to.
I will try to charge it with R134a next week and go from there.
I have had people tell me about hot shots but I couldnt find it, it will be my luck that next time I go to Kmart I will see some on the shelf, lol.
Thanks for your help Donald, im sure more problems are to come with my car, always my luck, grr...
