Answer
I have a 2004 Chevy Impala, and the windshield wipers only work on high. Need help with this issuue.
When it cuts off, do all the lights cut off at the same time? If yes, normally the negative battery connection is corroded or the bolt is stripped out. If there are no engine codes or check engine lights but the head lights still work, then the ignition switch is tested, after that the PCM is replaced. Every other part in the system will set a code.
