Excellent idea, seeing as how when one of the two filiments go within the parking/brake light bulb, the others are not long for the world. I use the heavy duty bulbs; they cost a few pennys more, but will take some abuse from those that off road.

Mine did that and it ended up being a bad multifunction (turn signal/wiper) switch. I couldnt get the left turn signal to work no matter what I tried but a new switch fixed it.

x1000 on fluid. Do a full blinker fluid flush (not just a change) when replacing. Make sure to replace the copper washer on the drain as they're known to leak after. just kidding.

Seriously though, I'd go with the flasher relay because it's designed to do that if a bulb is burned out. It's under the dash on the drivers side. It's either that or you have something fooling the circuit (did you switch to LED's?). Usually, the amount of load on the circuit determines the interval of the flashing (to an extent). I hope that makes sense? If you haven't changed anything and it just started doing it, it's likely the flasher relay. Relays do go and there's also not much more on that circuit.

Ohhh hahaha I read the first post not realizing the original post was 2011! LOL.


You've got a 2009....? If so, yours goes through a Smart Junction Box, not a flasher relay... You have the mirror ones too and they're good as well (although that shouldn't affect it anyways)? That's not good because it's computerized and set to flash it 80 times per minute or 160 times per minute if a bulb is out. I would buy a cheap pack of bulbs and try one side and hope it works if that's the case...
