It is a black box with a 2 or 3 wire plug-in. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Hello,

The flasher is interrogated into the hazard switch and some have a separate flasher than the Hazard switch. Located in the dash behind instrument panel cover above steering column. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

They are either part of the hazard switch or controller by the switch.

You have to remove the hazard switch and replace it-its built-in.

Take a flat head screw drive and pry the hazard button off. This will break the old switch but it will expose the part so you can get it out. Take the same Medium size flat head and slide it next to the switch at the 4 o'clock position, take a needle nose and grab the switch in the middle. By pulling on the switch and wedging the screw driver between the dash and the switch you will be able to release one side of the switch from the dash. Now without letting go of the switch with the needle nose, take the screw driver and wedge it in at the 11 o'clock position. This will release the other side of the switch. Give it a pull and the whole thing will come out of the dash. Disconnect the wires via the plug being careful not to let the wires pull back into the dash and plug in new switch. Then simply slide switch in the opening and it will click into place

I am pretty confident that you have a wiring issue. The only way they can stay on is if they are getting power from a different source then the circuit the fuse is on.

If you can turn the flashers on and then pull the fuse, you can then test for power through the circuit until you find where you have it. Clearly you should not have any power when the fuse is pulled so when you find power then you just passed the short.

Lastly I just want to make sure you pulled the fuse for the hazard switch and not the one for the turn signals. They are different.

Both have stopped working. Fuse? Where is it located? Is there a "flasher module"? Where is it located? Do you have any other "tips?"

Check fuse labeled turn signal (15 amp) in the left instrument panel fuse block. Most likely it is the relay though, it is actually part of the hazard switch, left center of instrument panel.

The turn signal flasher is integrated into the hazard flasher and is located under the dash on the passengers side or in the hazard switch itself. Here is a wiring diagram and location (below) so you can get the problem fixed and some location and how to diagrams.

Here is a guide so you can do some testing

Please let us know what you find.

Cheers, Ken

There is a buzzing sound from turn/haz flasher when t/s is turned on. Replaced flasher, still does it. Replaced t/s switch, still does it. Hazard lights ok. Just a buzzing from the flasher when t/s are used in either direction. It does not occur all the time but when it does there is just a buzzing sound no lights or indicator lights.

Check and test the turn and hazard switch-turn signal circuit goes thru there before gets back there/front

Cannot locate directional flasher to change it. Checked both fuse panels and under the hood.

Thank you

I think it may be part of the hazard switch. What are they doing. Are all the bulbs ok?
