'97-4.0L SOHC-50k
A/C just starting this habit of kicking on and off the a/c compressor when the truck is idling?
Seems fine when I'm driving. A/C could be cooler.
Does this sound like a low charge or is there a limit switch that cycles the system on and off at low RPM's when there is problem somewhere else?

Any ideas?

Thanks!

Its time to have the system recharged.
 






Im having the same problem. It started when I put my supercharger on. I thought maybe it was the a/c compressor. I recharged my it; The problem still existed.
My engine seems to have alot of stress when im idling. Is there anyway i can make this better. Maybe raise the rpms?

96 explorer 4.0l
10k on new supercharged motor.
80k on bolt-ons around the engine.
 






there's a sensor that checks the pressure of the a/c system, when the pressure gets too low, the compressor simply turns on. all you need is a little recharge like mrboyle said.
 






Thanks for the quick help!!

Now, I have to find somewhere to buy a can of R-134a and a tap line in WI?

I would recommend checking the pressures of the system prior to adding any more refrigerant.

Good luck.....
