So I've got a 2003 chevy blazer 4door 4wd blew the Cruze fuse a couple of times then brake lights would stay illuminated found the problem it was the multi function switch probably 2 months go by and it blows the fuse again popped a new one in and the whole car got janky i have no coolant temp or fuel gauge abs seatbelt security airbag and battery lights are on my gear selector doesn't select on th dash but my prnd all show up if that makes sense and now the car just wont start sometimes have fuel have spark when it doesn't want to start i crank it it will fire then immediately turn off

 

What fuse are you blowing? Does it keep blowing when you replace it?
