Code 33 AC Clutch Relay or Circuit

[GESYMSB]

Hello folks, after 5 to 10 minutes of driving, my Concorde 94 Service
Engine Light pops-on.

I twice ( to make sure ) did the code check by tuning on - off with the
ignition switch, and always end up with Code 33.

I believe is AC Clutch Relay or something like that not working
properly.

My AC works great, so any suggestions where to start looking ?
Or Most likely what the problem is ?

Thanks.
