Where is the low pressure cut off on my 03 Expy? I assume its on the accumulator/dryer? Is that mounted behind the ECM on the firewall?( I uploaded a pic, it's it behind it? AC has started to have intermittent issues, now it won't run at all. Static pressure low side is around 120, didn't check high side nor have I crawled under it to check for power at the compressor. I was "assuming" the low pressure switch went bad? For about last week when I first start it, it doesn't cool at all. After its warmed up(engine) for about 10 minutes, I can shut it off and restart it and then it runs. Today, it won't run at all no matter what I do. Also, I was thinking it could be the gap in the clutch being to big, and when it is warm when things expand it runs then... Again, I haven't crawled under it or delved into it to deep yet, but any pointers in where to look first would be appreciated!
