After encountering an unusual electrical problem that prevented our Prius from passing the ADEQ smog test, we went to the Toyota dealership only to be given a shoulder shrug and telling us there was nothing wrong with the car - yet we still couldn’t pass the test. Highline took the time to troubleshoot the situation, and discovered someone had wired a vanity mirror into the electrical portal used to check for smog. Not only did they troubleshoot and correctly identify the problem they ALSO took our car to the ADEQ smog check facility & got it inspected & passed certificate!
