`01 SL A/C problem

I think I already know the answer to this question, but wanted to bounce it off people who know more than me. The air stopped working today. I noticed that the clutch doesn't seem to be working (disc on compressor pulley not spinning when a/c is on). I checked the low side pressure, it was at about 100 psi and about 84 degees outside air temp. I have good voltage at the compressor. I assume the clutch is bad. Does this sound right? Thanks for any advice.

More than likely. The other thing to check is the switch by the fuse box. I can post a video if needed.

That video would be great. I took that switch off and cleaned it, but wasn't sure how to check it. Is that the pressure limit switch? The wire colors didn't match my haynes manual.

Do you have power/ground to the clutch? If you do then its bad if you don't than keep looking.

I have power at the connector going to the compresser. I don't think I can check the grounds as they are internal to the compressor. Is it possible to change the clutch itself? Or would it be better to just change the compressor? Thanks.
