a bad blinker bulb. replace the bad one and it'll blink fine.
often the blinker is made to blink faster when there is a bulb burned out
Why would you want the blinker faster. They should blink at factory specs.
try replacing the blinker under the dash that little box that makes the blinker sound
You must be out of blinker fluid.
The signal flasher relay may be on its way out.
blinker are you serious? BLINK !
If they turn on but don't blink, you probably need to replace the signal flasher relay.
It sounds like you have a turn signal bulb out probably the left rear.
Check all of your turn signal bulbs. One of them may be burned out.
It has been my experience that when the blinker comes on but the lights don't blink there is one or more bulbs burned out. If that is not the case check the flasher.
One of the bulbs is burned out. Turn on the blinker and look at the front and back turn signals to find out which one.
your blinker will turn on but not blink if a bulb has gone bad on that side or if your relay or fuse has gone bad
