My right turn blinker has just started rapidly blinking when I use it. The left blinker is still going at standard speed, but the right one has suddenly started rapid blinking. What do you suppose is going on? Should I take it to the repair shop to get it replaced

REPLACE THE TURN SIGNAL BULB THAT DONT BLINK.MOST OF THE TIME IT IS THE ONE NEED REPLACING.

sounds like you got a bad bulb. turn the blinker on an step out to look at them. there should be a blown one.

There could be several things that will cause your blinkers to stop working. Most will have to be diagnosed by a QUALIFIED automotive electrical shop but there is one thing you can try first. Step one is to turn your blinker stalk rapidly between right and left turn. Don't damage anything, just go back and forth several times real fast. Next, turn your emergency flashers on and off. Rapidly, like you did with the turn signal stalk. Again, don't damage anything, just do it as rapidly as you can, several times. What you are trying to do is clean the contacts inside the switches. Those two circuits work together to operate the turn signal lights and the emergency flashers are rarely, if ever, used and the contacts get a little corroded.

You might check the courtesy cornering lights that illuminate and do not blink. These go on to shine on the front corners of the car. Since they use electric when the blinkers work, it may make the blinkers work faster if the cornering bulb is burned out. You probably are not noticing that the cornering light is not on.

Flasher relays relies on bulb wattage for the speed of the blink.
You probably just have a blown bulb in the left rear blinker.:)

the rapid blink is because there is a bulb outage some where, Pull Over turn on left Blinker Get out of your car look at the front left blinker hen walk to the rear of your car and look at the left rear Blinker light then do the same for the right side blinkers if all are working rapidly your left right switch is bad

It's the bulb. There are two filliments in the bulb. One is for when you turn your lights on and the other is for breaking and blinker flashing. When the break filliment goes bad it causes the blinker to flash very rapidly. 100% the bulb. Change it and all will be good again. P.S. if it were a fuse none of the break lights or blinkers would work.

Usually a fast turn signal means that there is a light out. You should probably check all of your lights, including back-up lights, and turn signals. If there is one out then replacing the burnt out bulb should fix the problem.

hi usurally when that happens that means you have a bad bulb or bad wiring.

Look at the second page of the diagram at the link. The flag "E" in lower right has power coming from the switch. It goes to the instrument cluster, right mirror turn indicator, and right front turn bulb. Is the instrument panel light blinking? How about the mirror? Use these facts to find the break in the wire. If none of these lights is blinking, the switch may be broken, as yadayada indicates. See page 1 at the link. It has a separate contact for the rear light, which is why the back can work and not the front, even though the switch is broken.
