Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.THe AC error code indicates the blower vacuum switch is closed and should be open.See below:
Check continuity on the switch.WE should not have continuity until blower comes on and pulls a vacuum on the switch.The issue may be a defective switch ot defective board reading switch closed.Let me know if switch is closed or not and we will go from here.
