I have a 2009 Versa that the compressor also runs for 8 seconds, then shuts off for 8 seconds. It will constantly do this as long as the ac is engaged. My freon pressure is 50 over 230 while compressing. The pressure never rises over 250 or drops below 40. I replaced the pressure switch by the condensor to no avail.

You can review the AC system and diagnoses in the FSM. I'd spend a little of my time on it, then I'd haul it into an AC specialist and have them run a diagnoses and recommendation. The manual diagnoses steps seems to start on page 31 of the MTC chapter (page 22 if you have some consult tool things).

Seeing as how this has happened to more than one vehicle, please post your fix when you find it. Thank you.
