No Power to Blinker circuit

Hi,
We are having a problem with Power to the blinker system on a 1991 Ford F250 truck (7.5L).  We have looked at Fuses F5, F9, and F10.  All are good, but we don't have power on either side of the fuses when the truck is turned on.  Does anyone know if there is another fuse or circuit breaker upstream of the fusebox that powers these circuits we can check?
Thanks!

There is no car alarm on this truck.   According to the Haynes manual, the power comes from the Ignition Switch and is enabled when the truck is switched to the run position.  But it doesn't show any other fuses or circuit breakers.

    Do you have a test light to find a 12v keyed power supply Use it to find out if your keyed power source and supply are working.You should be able to find a good source of power at the plug from the back of the ignition barrel.Make sure the power in and power out wires are working.If they are there should be power at the fuse block

What would cause the blinker to blink very fast and the left rear blinker doesn't work.


You obviously have a bad connection somewhere in the taillight. Some trucks it is a common problem and the taillight circuit board is the problem.

My brakelights are both not working after changing the bulbs, changing brake pedal sensor, and checking all fuses. The running lights, parking lights, turn signals, hazard lights all work. Please give me...


Probably the blinker switch ..The brake light circuit runs through the blinker switch..Let somebody look and while you have the brakes applied move the switch around and see if the lights come on

Where is the turn signal fuse. It had a noise indicator when the turn signal was on, now it and the turn signals do not flash


i assume you are talking about a 1991 ford f350. if so i believe the blinker switch or blinker switch fuse is located on the fuse box underneath the dash board. you'll have to remove the dash board "belly pan" to gain access to the fuse box. the blinker fuse is a shiny square "odd" looking push in fuse. i believe it has a small aluminum casing on the fuse itself.

but....
it could also be a fuse relay witch is located under the hood on the driver's side fender well, but i'd check the blinker fuse first...

Check your fuses under hood and on dash. Some of these use two different fuses for rt. & lt. Look in you owners manual for the correct fuses to check. If it is a fuse problem, you will have to find out why the fuse was blown. Good luck

Check the plug at the back of the truck for corrosion. The brown wire entering the truck plug should be the the running lights, if no juice at truck plug in, you need to trace it back to the source looking for broken, pinched, wires, or poor connections.

Turn signals and back up lights dont work, bulbs and fuses good. Blinker lights only work in dash when emergency flashers are on.


Test the circuit board wires on the back side of your taillights where the bulbs go in to see if power is going there with the blinker on, if yes replace the circuit board (quite common with these trucks). If there is no power back there check your flasher relays for each turn signal, assuming they dont click off and on when you tip the turn lever. if all else fails, head for the multifunction switch behind your steering wheel inside the column that your turn signal/wiper/cruise control lever is connected to.
