I have a '91 s10 4.3. My left turn signal lights up, but will not blink. However, it does blink when I run the hazard lights. My right turn signal does nothing at all at any time. I figured I had a bulb problem, but that was obviously wrong. Also, on top of this, my brake lights do not work. Any suggestions?

 

check your multi function switch.The sitch that controls the hazards, the wipers, and directionals.
had this problem on my wifes 2003 blazer

 

Thanks blzrls. Turns out it was the turn signal switch. Glad to have that problem behind me. Hopefully no more will pop up for a while.
