I have a 99 blazer. Everyhting was working fine until today. I pulled into the driveway and seems like everything just went crazy. My rear window wont open anyway, dash, alarm pad, rear button. My door locks only work via my alarm pad. My headlights stay on no matter what they are set on. ALL happend at the same time. I pulled avery fuse I could, all good I really need some help!!!!!!!!!!

 

Scratch the light issue, Come to find out the lights automaticly come on in the garage, NoOb! But whats with the rear window and door locks??? I'm Stumped!!!

 

And I don't here the actuator doing anything. Checked my horn fuses and nothing. Even tried switching around the big fuses under the hood. Someone please help!!!!!!!

 

Look for a 3amp fuse under the hood. Even if it doesn't look blown, replace it and give it another try.

 

Thank You Soooo MUCH!!!! That was it! I guess it has happend to the previous owner a few times. There was a 10amp fuse in it's place. I replaced with a 2amp extra fuse from the inside fuse box. I have 3 Memphis 12's and 2 amps I was going to install tommorow. You just made my life a whole lot easier!! If your any where close to Asheville, NC. Please let me buy you a couple beers!!!!! Thanks again, Patrick

 

Glad I could help and I'll take you up on the beers if I'm ever up that way!
