88 GT.

AC clutch will cycle on and then off shortly after - will continue to do this as long as I am calling for AC - would this be an indication that the system is just low?

Note: the clutch does spin when engaged and there are no 'unusual' noise coming from the compressor either.

Thanks

Sounds like it's low. If you've converted to 134a, pick up a cycle switch for 134a and install it into the receiver dryer. It will make the compressor cycle correctly for the pressures of the new refrigerant. You can readjust the R12 switch, but unless you have gauges or know how much to turn the little adjusting screw, the $15 or so for the new switch is worth it.

Yep

Clutch Cycling Switch (R-134A)

That combination of numbers should cover just about every parts store.

The black piece on the clutch cycling switch is removable, it protects the terminals in shipping.
