Ford Super Duty (1999-2016) :: Turn Signal / Hazard Relay Is Clicking With Key Off
Apr 3, 2017
My neighbors 02 250 6.8l the turn signal/hazard relay is clicking with key off, sounds exactly like a turn signal when truck is off and switches are not engaged. Here's the weird thing, if you hit the brakes the relay stops clicking, if you engage the turn signal or the hazards the lights on the dash are in time with the relay as it should be, but when the turn signal switch or hazards are turned off the relay keeps clicking except when you hit the brakes. Also the turn signal will work with ignition off, if you pull the relay out the turn signals and hazards are inoperable but the brake lights still work. I swapped in a new relay and same thing...

Ok so my fire station has a 2003 f550 rescue truck with a rescue body with the round tail lights, we recently upgraded them to the LED ones that are much brighter but of course it flashes at the speed of sound. The question I have is:
1. the relay {flasher} is located on the driver side inner fender? I think....
2. does the same EP-27 relay/flasher fix the problem?

Example, if I'm turning the wheel to the left with the left turn signal on there will be a LOUD click, click, click ect. sound from the column. The sound is louder than the turn signal relay and can be heard with the radio on.
Today is the third time I've brought it in to have fixed and now they tell me it is "normal". They came to the conclusion that it is "normal" because two other trucks on their lot make a noticeable clicking sound and one is just as loud as mine. However, My truck JUST STARTED making the noise a few months ago and was quiet when I originally bought it.
I know this is not a big problem ,but it is annoying and I want it fixed. Anyways, my Ford dealer had bailed out on me so how do I fix it myself?
Can you hear the column switch clicking ALOUD in your truck?

I have a 2013 f350 powerstroke, and the other day i climbed in it noticed that with the right turn signal on that it wasn't clicking through the speakers. Then noted that the arrow wasnt lighting on the dash either. But the lights were still working in the headlight and the tailight. but not the mirror, where to start.

1999 ford F250 SD V10 ... When this goes on the truck misfires and tries to die. Usually I can key the ignition in nuetral and the clicking stops and the truck starts and runs better....

I have a 2006 F250 Superduty 4x4 that the brake lights hazards and turn signals have stopped working in the rear.. The middle cab brake light does not work either.. The running lights do work as well as the turn signal and all lights in the front.. I also checked the trailer plugs and both work for running brake and signal lights.. I have checked all fuses under the hood as well under the dash with a test light and i have nothing blown.. I have replaced the Brake switch as well as the flasher module under the dash and picked up a new multifunction switch (Turn signal/hazard) and that didn't work either.. I'm stumped at this point.. I have not checked the bulbs yet but wouldn't think they would all blow at the same time.. (will do this next)..

I was adding some more running lights today and tried to tie in to the front running/turn signal light. Next thing I know I hear a pop and now no turn signals, hazards or brake lights on my 99 F250 SD V10. My 3rd (center) brake light does work though when I press the brake, it's just the tail brake lights that dont work.
I can't find a blown fuse for the turn signals or brake lights (not really sure which fuse box it's in since the manual doesn't tell me what fuse is what)
I however did find what I'm guessing are the flashers behind the radio. What might have went wrong where before I start dumping money in to flashers and relays.
The next question is, can I jump in to the marker/turn signals and add another single LED light to them off the front? If I can which color wire does what?

Recently, I lost function of brake lights, turn signals, and hazard flashers. All happened at the same time. Some threads discuss flasher relays, short steering column wiring (position of steering wheel), and fuse failures.
I checked #18 fuse and a few others. All had continuity. I assumed my bulbs were all good. My hazard push-pull switch did not feel right. There didn't seem to be engagement. At this point, there was a good chance that the multi-function column switch had failed so I decided to try replacing it. I'm happy to report that this switch was the cause of all the light function failures and now, all is well again.
Removal is done by prying the key lock switch cover off,, removing three 1" Philips head screws that attach the lower column shield to the upper shield. At that point the upper shield can be completely removed. The lower shield was not totally removed because the tilt lever was left on. The switch is attached to the column with two 3/4" Torx 20 fasteners. The upper is easily accessible and the lower fastener can be removed by pulling the lower column shield down so access can be achieved. The two wiring harnesses have a conventional harness lock to depress and the connectors pull outward from the switch. Installation is the reverse of removal, noting the dowel locator and small plastic dowel on the lower shield.

I picked up a set of harley davidson look-a-like headlights online for my 05. I go to install them and when I tighten them up it causes the turn signal bulbs to push in towards the fender on both. I put my hand back there and it feels like the bulb socket is being forced against the header panel assembly. Am I missing something?

I have an 02 F250 6.8 with 51,000 miles on it. I recently replaced the battery about a week ago, and only actually drove it yesterday for the first time since replacing the battery. I drove it about 25 miles, parked, and when I went to restart, it wouldn't. The starter doesn't crank, so I mean its not a cranking issue as in cranking, and not starting. It only clicks at the relay when turning the key. It acts like when you try to use a wrong chip coded key.
All of the dash lights came on, and I can hear the relay clicking, but that's it. I swapped the relays around, and no luck. If I let it sit a while, about an hour, it will fire right up. The battery cables are tight and free of corrosion. I am curious, since I just put in a new battery, could this be the culprit? Why will it start fine cold, but not hot? I have NEVER had an issue with this truck until now.

My truck is a 1999 F-250 Super Duty 7.3 diesel. My left turn signal is fine. My right turn signal is going fast. The rear blinker lights up, but the front does not. So... no brainer... change the front bulb. I did. Twice. Sylvania 3157. It did not fix the problem...

New owner of a 2005 Passat GLS TDI.
For some reason, the Hazard switch clicks a few times after using the turn signals (randomly), or while driving it will start clicking for a few seconds. The lights do not flash. it is only the audible sound coming from the hazard switch area.
Where does that sound come from? the hazard switch? Would replacing the switch with a new one fix it?

I have a 2001 for f250 with the electronic shift on the fly and when I turn the switch to put it in 4hi or low nothing happens I don't hear a click and the lights don't come on but the 4wd light works it comes on when I first start the truck and I put different relays in that we're good and still nothing I tested the the relay box itself for power and there wasn't any.
I used the truck last year for plowing and it worked sometimes it wouldn't go In or come out but after a few tries it would end up working but I've tried everything I could think of I'm starting to think it's something electrical because the relay box isn't getting power to it but idk if a vacuum leak would do that or a bad transfer case motor or iwe solenoid or if it's something more like a broken wire some where.

I installed an EP27 electronic turn signal relay and changed the tail bulbs to Sylvania red 3157Rs in our Exped and everything works fine. I installed another EP27 in our Excur and the relay starts clicking when nothing is on and nothing else has been changed - all stock bulbs and working fine before.
No lights are blinking, but the EP27 turn signal relay is clicking away. Select left turn, right turn or hazard lights and they blink fine. Deselect the lights and the relay continues to click. Swapped the relay from the Exped to the Excur and it clicks, too. Reinstalled the stock turn signal relay and all is fine. There must be some difference or problem in the wiring, it doesn't make sense.

Buddy has a problem on his '03 F-450 cab and chassis. When he turns on a turn signal, everything is OK...but it goes out when he applies the brakes. Also, the brake failure light is lit up on the dash, despite the brakes being fine. These problems happened at the same time. I'm think a ground, but not sure where to look.

I replaced the bulb and it's still not blinking and doing the quick blink on the front and mirror bulbs.
The bulb turns on when on parking lights; it just won't blink.

I'm still fighting tow harness problems on my '01 F 250. I started by replacing the 7-way pig tail with a new one which didn't work. Then I undid all the butchering of the harness that was done previously. The factory harness had scotch locks all over it that were used to splice in a 6-way and a 7-way into the bed. I liquid taped all the nicks in the wires. Then I checked for power at the factory harness end where the pigtail plugs in. I have park/running lights, and one of the ports flashes for the left turn signal/flashers/stop lamps. I got rained on before I could check further up the wire. If I have no power to the wire further up is there another place to check?

While I know this has been covered before, I could not find anything pertinent to 2011-2015 model years.
So, I changed my turn signals to LEDs, and now I have the fast-blink behavior. I realize this is because of the significantly decreased amperage and resistance of the LED modules. I did a similar mod on my 2007, and simply found a replacement low-current blinker relay (on eBay, I think), and replaced it (it was physically located behind the extra small glove box near the middle of the dash.
My questions are, 1) for a 2015, should I use the same method of replacing the blinker relay? 2) Any brand and model that will work for this application and/or where one can be purchased and 3) Where is that relay located on the 2015 model? If not, should resistors be used?

I have never liked that the headlights are below the turn signals on the newer super duties. Has anyone swapped the positions so the headlights are on top? Will be ordering a 2016 next week and this would be one mod I would like to do. Not having the truck yet, I have not been able to do any investigation on what this would take or if it is even possible.
