It's been a while since I used my AC but it is blowing hot air.
I've fixed many AC systems on old Chevrolet cars that used R12 and understand the fundamentals. My NSX is a 95 and has r134.
My questions:
1) should I simply try adding more r134 and see what happens?
2) do I need to jump the low pressure switch to add it?
3) should I simply follow the standard r134 temp vs pressure curves?
Or
4) should I pump the system down and start fresh adding the proper r134 by weight?
