where is the top up valve for the a/c on a 2000 saturn ls?
I have an A/C button in my Saturn, but no cold air. I have looked for the top up valve in hopes that maybe it just need topping up. However, i don't know where this valve is.
The low side service port is the valve you are seeking. It should be located back towards the firewall near the condenser assembly. The high side service port is located in front of the vehicle on the passenger side.
