I have a 2006 Trailblazer and recently my turn signals have been working funny.
The front one are working at superspeed, but the backs won't work at all.
Does anyone know what I can do about this? I really need to get it fixed quick.

Thanks all!!

 

i believe there is a recall for these. As far as a quick fix i dont know, but the recall should save you some coin!

 

From past experiences with GM vehicles the superspeed blinker is an indicator that one of the turn signal bulb is burned out. Just my previous experiences.

 

like said superspeed- means one is burned out...
but why the rears are out?
I think that each rear tail circuit has its own fuse. check the fuses for the tailamps.
