Now, it will start, run and drive, but none of my lights (interior, brake, turn signals), except my headlights work. I have no radio, instrument cluster lights, no gauges and no heating/air.
I have checked all the fuses and none are blown. If it is the BCM, should I buy a used one or spend the extra $100.00 and get a new one?

Hello,

This could be a problem with your vehicle's fusible link 2. In the diagrams down below I have included the first page of your vehicle's Power Distribution wiring diagram, which shows this fusible link, as well as a guide on how to check a fusible link in an automobile. Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
