1996 Park Ave Interior Lights flashing when driving and parked
 

Suggestions for what to do.

When driving and when parked.

Slider for the interior lights is off.

Looking for the switch in the door to try and troubleshoot the problem. Is the dome/light courtesy light switch located in the door? Is there another problem that I need to look at?

Any ideas or suggestions would be awesome.

Looking for any ideas or suggestions that other people might have to help me with this problem. Not looking to get the dealer involved unless I have to do this!
