Hi, Thanks for the info.I needed to know which port the freon goes in. There is a port in the front and one by the passenger-side fender wall. The one in front is smaller than the one by the fender. I have tried adding freon to the front one and it takes it but the air does not get cold. Compressor does cycle.?

Thanks for your help : )

I'm sorry I miss read the question you want to use the small port that's the low side. Do you have a gauge on your charging hose?If so what does the pressure go up too while your a/c is on?Also was the system empty when you started charging it up?How many oz's have you added so far to the system?
