HOLY THREAD REVIVAL BATMAN!!! I have an 05 3.0 with this same issue. I know for certain the clutch is engaging, and it's spinning the compressor. I want to try the compressor control valve just for shiggles, but I am finding zero information on how to do it. I've seen those who said they did the valve (and it didn't help) but not how they did it. If anyone has done it and have a few pointers for me on the process or what to look for, I'd greatly appreciate it!

If there's interest in it, I'll do a proper write up w/photos when I do it. I just don't want to be completely blind when I start this.
