SS350
Checked the HVAC related fuses and relays in the console fuse box and all we're good. All the wiring harness that I could see looked good.
Pulled the compressor clutch relay in the under the hood fuse box and tried jumping across the compressor clutch load and line terminals without success. I did have battery voltage at those terminals.
I disconnected the wire harness to the a/c compressor clutch and had battery voltage at the connector with the A/C button on the dash "on" and did not have battery voltage with the A/C button on the dash "off'".
This test indicated to me that the A/C compressor iclutch is not working.
There doesn't seem to be a way for the diy'er to change the a/c clutch. I can hardly see it let access it.
Any thoughts on what to do?
You will have to remove the compressor. There was a person who changed out his engine and said he unbolded the compressor and left the lines on it.
If this can be done it doesn't look like a bad job to just change the clutch. A few bolts and some snap rings. The part is expensive but less than a compressor from Rock Auto.
Here is a picture of the clutch parts:
You may want to check the grounding side of the compressor plug. Would hate to see you buy a compressor or clutch, then find out it was just a bad wire connection.
I ordered a new clutch from Rock Auto. Parts.
Changed out the old clutch with from underneath and the right wheel well.
Unbolted the a/c compressor from the engine block without disconnecting the a/c hoses to gain enough room to remove the clutch. The hardest part was removing the 1.5 inch snap ring that held the coil to the compressor body. It's in a1.5 inches deep cylinder and very hard to reach with the compressor partly installed. I made extra long points for my snap ring pliers using 3/32 long handle Allen wrenches.
Took about 6 hours but all works good now. Just in time for the heat wave.

Good for you !
Glad to see you can think outside the box.
Sorry the job took that long.
