Turn signal works periodically, even with a new bulb.

Check the fuses first and if they are ok it could be the turn signal switch or multi function switch..

You need to check for power to rear light if none start to check wiring in reverse. Usually at turn signal switch or under drivers side carpet.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

did the housing come with new sockets? if not may be a bad socket or bad bulb.could even have a bulb in wrong.

The rear left turn signal bulb must be replaced immediatly before it melts the light socket, if it has'nt yet. Also please verify that the correct light bulb is being installed. because even though many bulbs look the same they are not identical. Installing the wrong bulb can be the begining of many, many problems in the particular circuit

Both turn signals use the same fuse. If the left side signal works, you may have a burned out bulb on theright side, sometimes even a side marker bulb can cause the problem. Or the turn signal flasher could be worn out, but this usually effects both sides. A third problem could be the turn signal switch. The switch is located inside the steering column and does require some special tools to replace it.

First: press the brake and be sure that both sides light up. If one side does not, turn your attention to it. Remove the taillamp assembly from the suspect side and disconnect it. Unscrew the socket / circuit board and dismount it from the reflector. Take out the bulbs and examine the sockets, looking for melted / toasted / warped sockets. If they are bad, don't even bother trying new bulbs or attempting a repair; go to the parts store and get a new socket / circuit board assembly. Last I looked they cost about $25 apiece.

There are dual elements bulb and single element bulb.

You need to see is there two contacts inside the socket.

If you accidentally put a single contact bulb into dual contact socket......it will cause this problem.

Check it out.

Check the front and rear bulb while trying to get it to blink. I think you will find one of your bulbs is or has gone bad.

You need a new Multifunction switch...Its very common. The switch controls those functions and more. Its hard to explain how it works but I am pretty sure thats what it is.....
