Ok...update.
The switch didn't do it.
I hooked up a pressure gauge and it reads 0 when the AC is on and the clutch is engaged.
With the AC turned off the pressure is 60lbs.
So I can assume it's holding pressure, at least on the low pressure side.
When it cycles, the clutch is not engaged...
My air quit working so I thought it would probably just need a recharge since I've never had to do anything to it.
The pressure is actually fine but I noticed the clutch cycling on and off repeatedly.
What should I start looking for to fix it?
Thanks
Jim
