Back story: I had my Escape A/C recharged over a year ago. When the mechanic removed the connector from the low side port apparently he heard it start to leak immediately. He said he tightened the valve and the leak stopped. Some time later the A/C stopped working again.
Since that time I've acquired the tools to properly recharge the system myself and I did so today. When I took the low side connector off after recharging I noticed some dye and liquid bubbling from the low side port. I recapped it and left it for a little bit. When I came back and took the cap off I could see the dye and liquid inside the cap as well. I took a picture of inside the low port and the valve stem is visibly bent.
So I am assuming that Schrader valve is past its usefulness but am I heading down the right path with my thinking? When charged the system blows very cold, the compressor kicks on, and everything seems normal other than the low side port issue I described.
