it there any adjustment on the ac compressor clutch?

whenever im at idle in park the ac runs fine but as soon as i put the truck in gear at idle the ac clutch kicks off.
ccan i adjust this at all?

 

there is a spec for air gap in the clutch, but that doesnt sound like your problem. i seem to recall a post or two about some device behind the dash that you can adjust. not positive what it adjusts though.

are you blowing really cold air when it is on? most a/c systems will cycle on and off if there is not sufficient freon in the system.

i'm not real familiar with toyo's a/c setup. (yet)
