Can the cycling switch be replaced without unloading the system on 1996 a Chevy 1500?
Yes, unless someone has removed the scharder valve in the port under the switch. You will loose a small amount of refrigerant when unscrewing it just as you loose a little air with a bicycle pump.

Thank you very much for the info. This system has been a complete pain. I finally observed that while the sytem is on and the compressor running, if I gently push on either side of the cycling switch it shuts the compressor down. I was hoping not to have to evacuate again. Thanks again
It may not be the switch- but the connector to it may not be sueazing the pins tight enough- have seen it before- I use a pick and bend the clamps a little. The switch may be fine.......

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
