‘94 Silverado A/C INOP ?

[highwaystar]

1994 C1500 Silverado AC compressor won’t come on. I added 134a, pressure reads in the green band. I jumped the low pressure connector and the compressor will work. I also replaced the low pressure sensor, still no joy. What to check next? Thanks!

Your charge may be too low still, the low pressure cycling switch will open somewhere around 20 - 25 PSI. Or, you may have a bad pin in the connector which isn't making a good connection when put in place.

"Green band"? What is the actual pressure?
