hey guys i got a 2001 ranger 4wd 4.0L
it idles a little low with nothing on and when ac is on the truck wants to stall bad i cleaned the iac valve and changed the mass air flow sensor the compressor clutch is free and blows cold im stumped is there another sensor or soleinoid that would fix this problem please help a fellow ranger out thanks

 

Vacuum leak?
Seized compressor could be causing the problem.....

 

Could be a vacum leak is there a way to test for that I know the compressor is good the clutch rotates free so thats fine. Is there a sensor that works with the compressor to make it idle higher when it draws power
