I am not sure I see the correlation between fuse 9 and the lighting system.

That means we can assume they are not causing this. Fuse 9 is for the transmission range sensor so if it keeps blowing then I suspect the sensor is shorted or another component on that circuit is the cause of it.

Let's test the wiring for this and make sure there is no short.

Let me know if you have questions on this and we can go from there. Below are the wiring diagrams and fuse layout to show the TRS is the only thing on this fuse.
