2005 Buick Rendezvous Lighting problems

I was driving and my headlights flickered then I lost low beams .. Parked and went back out to go to the store and I had no lights low beams wouldn't work fog light stop working and high beams stopped working look in fuse box to see if a fuse blew and 6 fuses blew and shot sparks out of the fuse box under the hood. *Tr

Update: prior issues were due to bcm failure which that was my assumption based on numerous owner reviews. This part is a major safety issue if fails and buick is aware and won't recall. These should last for the life of the vehicle. Occasionally one will go bad but shouldn't. The fact that many rendezvous models face this issue of failure prematurely shows that it is a defective product! Many have almost dies due to this failure. Car shutting off and lights going out while driving down highways/ expressways. *Tr
