What causes a new AC compressor clutch failure?
Clutch failure is usually caused by high pressure or voltage issues, or a combination of both. With a wrong charge the pressure switches will cause the compressor to constantly engage and disengage. If there is not enough charge the compressor will overheat due to a lack of oil circulating.

Suggest that you start with the basics like checking if there is power supply to the compressor by checking the fuses and wiring. If the relay is fine, after checking the fuses and wiring, check if the AC switch on the dash is working or defective.
Where is the low pressure switch on civic a / C compressor?
You want to jumper the wires on the connector that attaches to #19. This part should be around the drivers front, standing in front of the car with the hood open, it should be bare aluminum and around the size of a soda can. Looks like you got the high pressure switch there. The low pressure switch will be on a part like this.
