The L series has a variable displacement compressor, mine stuck at zero displacement and I had to replace it. Check to see if your car uses a similar compressor, that could be all that is wrong.

The system is controlled by an expansion valve at the firewall. Several manufacturers have used this system over the years. It allows for constant compressor operation with variable flow. My mother’s Cadillac had a similar system back in the sixties smooth operation with no clutch cycling.
