I recently fixed this issue. Interior and cargo lights would come on and off while driving. More so on bumpy roads. I used canned air to blow out the connector located on the left side of the cluster. I also hit it with a small shot of electrical cleaner. So far so good.

Update on issue. It is not completely fixed. It doesn't happen as often, but doesn't happen when wiggling wires at the plug so I am thinking there may be another cause. When it cools off (hopefully soon) I will give the door switches a look.

Based on what I've read on this forum in the past, and as previously posted here, it seems likely it's caused by a solder joint on the cluster that has a hairline crack. You could look for videos showing how to fix that. Or if you're handy with a soldering iron and have one that can heat up to say 850 degrees, you could just briefly remelt each cluster solder joint.
