Blinker issues on 1996 blazer
 

Ok, during the day when my parking lamps are off and headlights are off to, my right brake light is out and my left front turn signal blinks at a diffrent time then the rear. At night with the headlights and parking lamps on the rear brake light works and the blinker problem still remains. Does anyone have any ideas as to what this would be???

Start with checking & replacing ALL of the bulbs (not headlamps) check cleanliness of contacts as well,look for obvious wire abrasion or broken sockets,and then maybe put in a new HD flasher unit! Also look for shoddy installation of trailer power hookups!
