My dash a/c is not putting out cold air. I read all the posts on Duracool but NAPA said I could not buy it anymore. I bought the conversion kit from R12 to R134. Came with the adaptor, a can of oil neutralizer and three cans of R134.
I changed the adaptor and connected the oil neutralizer then installed two of the three cans. Noticed the compressor was not turning so I jumpered the low pressure switch. Compressor started turning but did not sound like it was compressing. Attached the third can or R134 and it took all that also. Still no cold air. Removed the jumper and the compressor stopped turning.
Do I need to put in another can?
Is my compressor bad?
Any ideas would be appreciated.
When I remove the pin from the schrader valve to put on the R134 adaptor, there was no pressure coming out at all.
Thanks

Mike,
There is a lot wrong here..
The guy from NAPA said you couldn't buy Duracool and you believed him without doing any research? He may have been trying to tell you that he can't sell you Duracool or any other HC-12(a).
It sounds like you bough a service kit that is a few cans and tapper-connector.
Did you just connect the can to the low fitting or do you have a service gauge set?
If you are changing from R-12 to R134A, the system must be cleaned of old oil (I don't care what they tell you, R-134A will react with the mineral based oil that is in an R-12 system), then evacuated as R-134A will react with any moisture that enters with atmospheric air and form corrosive products.
If the system had no residual pressure, then it is almost certain that air has entered. You may need more work than you thought.
