does anyone know if it is normal for my 2002 hd150 with climate control, the air cond clutch cycles (15sec) on and off ,even after the motor is warm, control is set to "auto" outside air is 56-65 and temp of control is set as high as 90 ,but in auto the air cond clutch keeps engaging then disengaging?

 

Hmmm. I would have to listen to it. I haven't noticed it cycling on mine.

 

An air conditioner can cycle more often if there is a refrigerant leak and it is getting low. If it were mine, I'd schedule it in for a check out.
