Get code(s) with either the key-on, key-off technique or by reading the code with a code reader or a scantool.
Post the EXACT code here for comment.
It's the only way to go here...........................

when you run the heater the ac clutch will cycle on and off if the ac is not operating the clutch wont kick in ,this is most likley the reason for the code being thrown ,do you no why the ac does not work, leak ,causing all the freon to escape or bad clutch
