Randomly my blinkers cruise and parking lights starting having issues. I fixed the blinkers which just stayed illuminated instead of flashing that was solved via a new relay. Now my parking lights are stuck on, and while this happens the chime will sporadically go off even though there is no key in the ignition and the headlamp selector is in the off position.

Couple questions. First are the front and rear parking lights remaining on?

If they are then we need to check voltage going into the under hood fuse block from from the hazard switch.

Once we know if there is voltage coming into the fuse box we can pretty much confirm this is a switch issue. However, if there is not then this circuit is getting power from somewhere and we will have to find that source.

More than likely this is a switch issue so let's start with this and go from there. I attached the wiring diagrams below for your review. Let us know if you have questions. Thanks
