My left side blinkers started blinking at mach 10 today while the right side still blinks like normal. How can I fix it?Is it a relay or something?

 

One of the bulbs is out...

 

either the bulb is out or you dont have a good contact on one of them....lol mach 10

 

How dare you post this in Electrical!

Don't you know you're supposed to check the Lightning Forum first, before posting in the correct Forum?

I already replaced the front one.........to no avail (even though it wasn't working,it does now) still got the spaz mode goin on.The rear turn signal bulb does work...............

Raoul,
I forgot that all questions need to be seached for in the lightning forum

 

Sounds like the multi-function switch is bad. Does it work right if you only push on the lever hard enough to get the bulbs to flash but not lock on?
