This is normally an ignition switch issue so I would suggest replacing it as it is not that difficult on these vehicles.

I will attach the info below but I would suggest just checking the voltage coming out of the switch to see if it is cutting the voltage off to the coil. This will confirm the switch is shorted.

Below you will find the info from the manual that will give the detail that you need to test and replace it.

Please let us know if you have other questions. Thanks
