Radio or blinkers speedometer gas gauge don't work but car run headlights even work
If you have that many failures all at once, it's generally a bad BCM. Body Control Module. If you go to Ebay, you can find them really reasonable. About $20-$40. Or you can pull one from a local salvage yard. I just checked Ebay and there's a few for sale.
Just a quick note. If the BCM doesn't cure the issues, you may have to put in a new gauge cluster. Have you checked fuses and blinker relays first? It may be a coincidence that everything failed at once. But before purchasing a BCM, I would check or replace the fuses and relays. If your check engine light is on, you might want to have the error codes scanned as well.
