Compressor working, cabin temp doesn't get to setting before system shuts off

Just bought a 96 deville. computer reads service ac system compressor off. Took it to my mechanic. He said it looks like someone probed all the wires to get rid of the code. also said the wires probably weren't put back right. worked on it for approx 2 hrs. cannot get any juice to the compressor, please help System is fully charged, compressor cycles on and off. I think the passenger cabin temp. sensor could be off. It shuts down after just a short time. Cabin temp is no where near the auto adjusted temp. setting.

If my freezon would be low then why is it very cold air when I'm going on the road
because the temp difference between the hi and low side will be greater faster than a normally charged system the reason it cycles off is the keep the evap. from freezing up, but running to low on Freon can cause poor lubrication in the compressor causing damage to the compressor, yes it will blow very cold for a short period of time with a low charge

Do you have any stored codes in the computer ? If a problem occurs that could damage the compressor, the computer will deactivate the system until the problem is fixed and the codes are erased.

My ac went out on my 98 cadi deville a few month ago. It just tells us low refridge. we tried to put some more in and the gage to fill it up says it is still full. but since then my econ/vent; heater; rear...
on those caddys you disconnect the battery and wait a few seconds and reconnect and it will reset ac system. when it goes into service mode the system just shuts down. the battery procedure is how to reset. when the ac compressor is not engaging you will not get an accurate reading on your gauges. it might be low but the compressor must be engaged for the system to take more freon.

A/c system kicks on and off randomly
If the cabin temperature is remaining cool, the cycling of the compressor is pretty much normal as long as it isn't happening frequently and allowing ac inside to not cool. Operation is controlled by sensors that detect both cabin temp and system pressure.
If it is not cooling correctly one of those sensors may need to be replaced, or there is a partial restriction that is causing incorrect pressure readings..
