Default A/C compressor issue

My compressor keeps clicking on then off (for about 1 sec.) it keeps doing this about every 10-15 second intervals. I don't Ned air right now since it is winter. Can I disconnect wire harness temporarily until I have time to diagnose is the spring?

Pretty sure thats normaly how an AC clutch works, cuts in and out unless you hav AC on it stays on.

Thanks, I didn't know that. But should it be noisy? I can hear it clicking on and off, it's kinda loud.

Rapid on/off cycling of the clutch indicates a low refrigerant charge and is not normal operation.

Even in the winter, the AC is used to remove moisture from the air inside the vehicle when using any of the windshield defrost modes.

If you are low on refrigerant, it may just need a can or two to top it back off. But if you would rather wait for warmer weather to inspect and repair, you can just disconnect the clutch wiring.

there is a low-pressure sensor on the accumulator--the compressor is likely cycling off due to a loss of refrigerant . . . if you disconnect the electrical connection to the sensor, the compressor will not run . . . you probably have a leak somewhere, hence the low pressure
