turn signal not working?

Actually, you could be right. In the past, one simple, reliable thermal flasher was used for left and right signals, and a different thermal flasher was used for the hazard flashers. Today, the engineers use a special electronic flasher that has three different inputs from the signal switch. The desired circuit, left, right, or both, is selected by the electronic flasher, not the signal switch as before. The advantage of this circuit is it makes the signal switch extremely simple and inexpensive, and the flasher can tell you when a bulb is burned out.

The fastest way to diagnose this is to plug in a different flasher assembly, but that means you have to buy a new one or run to the salvage yard. A better alternative is to find the light blue/white wire and ground it. If the left signal turns on, the flasher is okay.

The flasher is usually hard to get to, but if you can, you can remove it, stick a small-diameter wire in terminal "A7", then plug the flasher back in. Use a jumper wire to ground that wire in the socket. Don't use a real fat wire as it can spread the terminal causing other problems later. Note that there's a mistake on the fifth diagram. They show two "B7"s and no "A7". If you use the wrong terminal, the right signals will flash.

You should be able to get to the plug on the multifunction switch without removing it. If it turns out to be defective, I'll post the instructions for replacing it.

after disconnecting my trailer lights my right turn signal flashes real fast like there is a burned out bulb. bulbs are good. when i reconnect trailer lights turn signal works just fine. any ideas? i have checked all bulbs and trailer connections and cannot find any wrong with anything

There are two bulbs in the front for the signal. One could be bad and the other working. check that and let me know what you find. Also, let me know if both front and rear are flashing.

okay, I have no taillights and my right turn signal does not work in the rear. I've change the bulbs I've changed the fuses and I don't know.

Hello,

It sounds like the combination flasher is out which control the blinkers and running lights, here is the location in the diagrams below. Check out the diagrams (Below). Please let us know what happens.

My driver side low beam works, but not my high. Then my blinkers stopped working all sides, but my blinkers still turn on and flash when i use my hazards.

might try a new combination flasher unit.

check for power at headlight bulb. or you could have a TIPM problem or related. some guys just run a crossover wire from other side.

oops check ground too.
