2005 Mitsubishi lancer

Your vehicle has similar signs that some VW's showed in the early 2000's. Depending on where you live, here in the Midwest, we found a main wiring harness that ran under the inner edge of the driver side, under carpet was exposed to salt and water during the winter. This caused connectors to brake and cause many issues.

As for your issue, seems that all these components may be sharing the same electrical circuit and therefore not working properly.
