forgive me God for saying this, disconnect the negative battery terminal for 5 minutes ... this will kill the keep alive memory ... reinstall the cable and see if the light comes back on ... if the AC switch was on during a self test by the tech, that's what set the code ... if the light comes back on, find out the specific code and post it ... need to know what it is before a course of action can be had
