My g/f's car is a 94 Grand Am and the A/C doesnt work any more. It slowly stopped working. I found what looks like the refill spot on a metal line that runs from the condensor to the pump itself. It has red cap on the top of it, would this be the spot to refill?

i think you fill from the fitting with the blue cap but not 100% sure maybe someone else can verify this.

 

I think there should be to little valve stem, on the condensor. I think you fill it up there. But don't quote me. Just wonder what those are for???
