Hello. I just learned how to do a/c recharge on my other vehicle and want to redo my 505. However I cannot find the "High" port. This car was converted to R134a some time ago and now the a/c is not working well.
I want to start from scratch because I suspect that the shop that converted it did not do a proper flush before conversion.
But. I cannot find the high port.
It's not in my Haynes manual and I have traced the system multiple times and still cannot find it.
Does anyone know about 505 a/c systems that can give me clue where to find the high pressure port ?
