When I turn on my left turn signal on the lights blink real fast and they are very dim, but when I turn on my right turn signal it blinks at a normal speed and the lights are alot brighter.

My question is, what is causing this?

Thanks

 

Are all the other lights on the left side of your car working? The turn signal will blink quickly if you have a short or a light out somewhere.

 

or if the plug underneath the bumper is loose. try reconnecting it

 

thats what i thought it was at first but all the lights work still, ill look to see if the connections are loose.

 

i forgot to post that it was a loose or dirty connections, i took both bulbs out on the left side and cleaned them and put them back and now everything is back to normal.

Thanks for the help!
