I need to replace my 99 mercury mountaineer electronic flasher for my turn signals and can't find it to replace it

The flasher units are different for turn signals and four way flashers. Not sure but most are under the dash not far from the steering column

See the lite blue wire that carries voltage from flasher to multifunction switch, with the turn signal on, that wire should be hot, use a test light to check for voltage. If wire is hot, I think the multifunction switch has a problem. If it isn't hot, I think the flasher has a problem or that wiring circuit.

It's the same flasher unit for both turn signals AND emergency flashers. Even though one side works, the other won't. If you have a good fuse for the turn signals, then replace the flasher unit.

Check your fuses first, then go on to the flasher unit. Repost progress.

bad earth to the ofending lights, burnt out flasher unit, worn switch. all assuming youv checked the fuse fisrt, after that check the flasher unit which should be in or near the fuse box and it will look like a rely so make sure youv got the manual or guide book befor you start pulling out the relays

check out the emergency flasher relay - may need new one.

You need to replace your flasher cam, to find this you need to turn your indicators on then look around under the dashboard for the thing making the tick tick noise, this is your flasher cam.

In mountaineer it is located on the steering column right behind the diagnostic plug.

your flasher relay is located in the central junction box, which is located under the left side of your dash and it also contains fuses for your turn signals and many other components

Check the FLASHER, also can review the Fuses, located inside the passenger compartment, under the drivers-side of the instrument panel.

Both the turn signal flasher and the hazard warning flasher are mounted on the fuse panel on the truck. To gain access to the fuse panel, remove the cover from the lower edge of the instrument panel below the steering column. First remove the two fasteners from the lower edge of the cover. Then pull the cover downward until the spring clips disengage from the instrument panel.

The turn signal flasher unit is mounted on the front of the fuse panel, and the hazard warning flasher is mounted on the rear of the fuse panel.




To access the fuses, remove the fuse panel cover. Note the spare fuses (A) and provided fuse puller tool

Power Distribution Box
Located under the hood, in the engine compartment. It houses the fuses and relays for most of the under hood components which are not controlled by a dash mounted switch (such as the alternator, fuel pump, ECM, etc.). The fuses and relays are replaced in the same manner as the fuse panel inside the vehicle. The power distribution box cover is hinged on one end and utilizes a retaining latch on the other. Simply release the latch and lift the cover up to gain access to the fuses and relays.

Hope helped with this; remember rated this help. Good luck.
