Ac not working
My ac isn't working. I checked the fuse under the dash and it's good and has power. The clutch won't engage on the compressor either. I don't have power to the plug on the compressor. I was told that it could be the ccrm (constant control relay module). Has anyone ever had to replace on of these? If so was it very difficult? Got any pointers?

There is a two-prong electrical connection on one of the AC pipes.
Unplug the wires and use an ohm meter to measure continuity.
It should be a short, ~10 ohms.
If it is open, then there is a leak and the freon has escaped.
If there is a leak, then it must be located, the bad part(s) replaced and the system recharged.

Both need to be happy.
But, if the compressor isn't running, then the evaporator won't be iced up and the high pressure switch won't have opened.
So, checking the low pressure switch to ensure continuity is a good first step to seeing why the compressor won't run.
