The license plate light and back left light fuse keeps blowing. I have replaced twice and it lasts for about 30 seconds before blowing again.

Hello,

If the light and the fuses keep blowing it could be due to a short in the circuit.
Best way to go about it is to trace the wires and find the issue. It could be that you have two uninsulated wires touching or has corrosion in the connectors.

In order to check the wirings you will need to use a multimeter. This will allow you to check voltage as well as resistance for the wires.

Here are couple of helpful articles:

I have attached the rear light wiring harness schematics for your reference.

Please let me know of any questions.
