I have an '01 S10 Blazer. Now, I know I'm not a complete idiot, but... When I turn the right turn signal on, it works great. However, when I turn the left turn signal on, it blinks super fast. I was always under the impression that when it would blink really fast, a bulb was out somewhere. My boyfriend and I have both looked at it and there are no bulbs out anywhere. None in the front, none in the back.I was thinking it could be a fuse or something...? I'm not sure but it really annoys me and I'd like to fix it so... Anyone have any ideas?

Thanks!

 

I would grab a new bulb and go around and swap one out at a time and see if it fixes it.

 

did ya try the signal flasher?? was a bulb rec replaced for sum reason and the bulb was installed wrong...
If this was August and i was heading out to Maple Grove for the NHRA races i would have ya meet up sumwhere and i would take a peek at it.. but its not august..unless ya wanna wait lOL.. who needs signals thats what fingers are for.. DOH

 

I would start at the left rear tail light. I have seen more than a few of the connectors at the rear tail lights corrode from moisture, causing odd electrical issues with the turns & tails. If I remember right, the plugs can be disassembled making it easy to clean up the corrosion if that is the problem.
