As the title says i just replaced my hazard switch because mine was broken. My son decided to shove my old one back in and i had to take it back out. Im not sure if in the process of removing it a second time i might have fudged up my multi function switch but once i put my new one in, My volts gauge will pulse, all my dash lights will blink and i believe i hear my fuel pump or something kicking on when all the lights come on. All of this happening when i depress the brake pedal. Im hoping i didn't somehow fry my blazer. My blazer is a 1995 with a 4.3 and 4x4. Sorry for the long post guys

 

Remove the switch and see if the blinking lights and such, quit acting up. Take a look inside and see if any of the terminals are bent, etc.

 

Here some pics or where the switch goes in. When the switch is pulled out there would be no flashing of anything but i wont have rear brake lights (except for third) and i have no turn signals

 

Fixed it a new multifunction switch,now i can keep on truckin now, when i get her all cleaned up i will show off some pics of my blaze.
