I've googled this, and have visited many web sites, but no one seems to have my type of problem listed.
This is weird. In the daytime, when no lights are on, my turn signals blink at normal speed. Ok. But, when I turn on my lights at night time, it doesn't make any difference if I'm activating my left turn signal or my right turn signal, the turn signals blink much faster.
Can someone please explain what I should do to fix this problem. Thanks a bunch!

First check all bulbs. Does your vehicle use same switch to active headlamps as well as signals?

No, the switch is on the dash, to the left of the instrument cluster.
All bulbs were checked a while back, (earlier this summer), and and I found bulbs on the front signals to be, (I'm at work, and trying to recall this), to be 1157, and the manual shows that they should be 1137. (?)
Now, don't get me wrong, I just seem to remember it was something like that.
BTW, I haven't had this but for less than a year, it was my son's before that, and it seems to have always blinked like this.
But, I believe the 1137 & 1157 are both dual filament bulbs.
Question) Doesn't the signals blink faster when there is a greater load?
Could it be that I simply need to replace the signal relay component, which I haven't decided to do yet, but I'm leaning towards that.
