I've noticed recently that my compressor is short cycling. At first I thought it was due to low charge but it is not happening all the time. More often than not the compressor and fans will cycle about 4-7 seconds off, 7 - 10 seconds on, but sometimes will run constantly. Could this still indicate low charge if not happening all the time or could it be another issue?
That seems like normal cycling for low fan speeds and/or cool temperatures. This is especially true if the econ button is on.
Could it really be normal to cycle that many times a minute? Wouldn't that wear out the compressor?
Considering the age of your vehicle....why not have the system properly serviced and then evaluate the possible problem. Cycling of the compressor is not a safety concern on the low side. This is a control function to prevent evaporator freeze up. Hi pressure cycling is another issue...yes, some vehicle will employ the use of HPCO switch to prevent excessive pressure build up. This is a system protection device.
Also ambient temps and evap heat loads effect cycling points.
Best diagnosis procedure is to know the system is properly recharged....then evaluate the system. Stop the guessing....know for sure.

You don't give the ambient temp it's cycling at? if it's cold, it may cycle that much, otherwise it's not normal,you have a drier/expansion valve system that cycles very little if at all during hot weather...Have your pressures checked and note the pressures it cycles at.. If just the compressor is cycling, you could need a simple clutch gap adjustment.. More information is needed...
