Ford F-150 - 1997-2003 :: Rear Turn Signals Fast And No Tail Lights
Jul 12, 2015
My '99 F150 is having wiring issues. It started with a left flasher being fast and the rear bulb not working. I put in new bulb and that didn't fix it. Then I realized that I also had no tail lights. The reverse lights are good and the brake lights work too.
So far I have searched for and repaired suspicious splices done by PO, added a ground wire that was cut off from the trailer wiring harness, checked every fuse that I could with an ohmmeter and I pulled the multi function switch and tested it with an ohmmeter also. It tested fine but I did find one of the female pin connectors had pulled out of the harness. I managed to get it back in and seemed to click into place alright. Somewhere over the course of all that I now have both sides of my flashers fast and still no tail lights. Good news is that I haven't broken my brake lights or reverse lights yet.
Could I have a bad flasher relay? Earlier in the process I did have my 4 way flashers working correctly and a couple times I even had the turn signals going. Now, none of the rear blinking lights work but the front ones go 90 to nothing and I still have no tail lights. My truck does have the auto lamp thing.

This has been driving nuts for 2 days.... Brake lights dont work. Either pushing pedal or turning on lights. Turn signals work just fine.
Cab/cargo/3rd brake light on back of cab doesn't work either. I have checked/done the following:
- Checked Brake pedal switch for continuity. Tested fine.
- put multi meter on wiring all the way back to brake lights. No drop in voltage.
- changed bulbs. #3157 dual filament.
- positioned steering wheel all the way up and all the way down as suggested on here. No change.
- checked multi function switch (turn signal switch) for wiring issues. None found.
- kicked rear quarter panel for caveman adjustment out of frustration. No change.
What am I missing?

I found out last night that all 3 of my brake lights are out. However, my tail lights work, and my turn-signals work. So obviously its not a big wiring deal. I was looking for the brake switch but i don't know where its at because i looked underneath. What fuse is the brake lights cause my manual doesn't have it listed. I drive a 04 Elantra GLS.

I have checked all fuses, checked wires on top of steering column all checked out ok. Hazards work but when I press brake tail lights just blink with no brake light but the 3rd brake light works??? Signal switch maybe??

I have a 2006 F150 xlt 5.4 3v. I've owned it since Oct. 15'. In approximately Nov. I lost the rear right brake and blinker light, and then around Christmas I lost the rear left brake and blinker. I also have no rear hazards, but the inst cluster flashes at a normal rate when the flashers are engaged. All running lights work, and 3rd brake light works. Front blinkers work and all other electrical works. Have checked all fuses and bulbs with no solution.

A friend of mine has a 2004 F150. The tail lights and the 3rd brake light are working but the rear brake lights, flasher and turn signals have stopped working. What could be wrong? I googled the problem and did find one person with the same issue in a 2001 F150. There apparently was a recall (#05S28) of the SCDS (Speed Control Deactivation Switch) but that vehicle kept blowing fuse 13. My friend checked his fuses and they were all ok,

Dad borrowed truck and wired 7 pin trailer harness. Lights worked on truck/trailer for use but upon return the turn signals didnt work. Hazards and running and brake lights did work. Replaced TS flasher and Haz flasher. Still no signals. Pulled steering wheel and replaced turn signal cam only, not whole switch. Now no brake lights, no rear hazards or turn signals. Losing my marbles trying to follow schematic and using test light and mulit meter. All bulbs and fuses are good. Running lights and head lights working as well.

I noticed yesterday morning that my turn signals were not working on my 2000 F150 4.6L 4X4 XL truck and I need diagnosing what the cause is. The hazards, windshield wipers and my brights still work so I was not sure if it was just the switch. I have done the following:
* I went and got a new turn signal flasher at the parts store last night but when I went to put it in under the fuse box under the hood it was to big to fit into the holes. By this time the dealer was closed and I couldnt go and get a new one from them. (I wasn't sure if both needed to be replaced at the same time).
* Since there are two under the hood i just swapped the positions and still nothing happened everything worked accept my turn signals still worked. (by swapping I mean I took the one that was in fuse location 301 and put that one into 304 and 304 into 301.)
* I went to my owners manual and checked every fuse to make sure that anything related to my turn signals and flashers etc were not blown and they werent.
That is were I am at. I don't think its the switch but is that a common thing to go out?

I just bought an 05 F250 XLT. I noticed tonight that the rear turn signals and brake lights don't work.
The front turn signals work fine, although they flash fast. I know that usually means a light on its way out. neither taillight flashes though, which puzzles me.
My second issue is that, of the 3 brake lights, only the high mounted light illuminates when I hit the brakes.

1998 F150 ....Left signal lights flash supper fast or not at all but if I pull the arm down (for left side again) but stop before it clicks in place, signal lights work normal. 4 ways work good; right side works good 95% of the time; all bulbs are good. So like Spotty suggested it's the signal arm switch? Does that sound right? Many years ago I changed it twice in my old Ford Taurus; twice because I was buying used from a wrecker.

I recently bought a 07 Expedition with light left front damage. After the repair I noticed that I'm not getting any power to the rear turn/brake, and backup lamps.The tail lamps and third break light work as does the trailer plug. I know that they were working prior to repairing the front. I did disconnect an aftermarket alarm during the repair. Basically all I replace was L/F sheet metal. Of cause I checked the obvious things like fuses and current to the tail light sockets.

I have a 98 f150 that I don't drive often. I had it out tonight and realized the my brake lights wouldn't come on unless I pressed the peddle down hard. Does the switch work off of pressure? They used to come on as soon as I would touch the peddle.

My sons 2006 F350 brake lights and rear turn signals quit working. When the headlights are on, all the lights operate but the rear turn signals and brake lights do not nor do the emergency flashers. The front signals work but flash very rapidly. Although I'm not an auto electrician, I'm fairly mechanically inclined but the fact that the front signals work, the rear don't and all lights work as lights, just not as turn signals or brake lights.

I've got a 98 Silverado. Break lights and rear turn signals won't work but tail lights and reverse lights work. Also the brake light on the cab does work.

I did my research and it turns out I need a relay switch for my blinkers. these bulbs are bright but flash too fast..
How do the relay switches work, what do i plug them into and do I need one relay switch per blinker?

I was turning left in my 01 Excursion and I think I hit the turn signal while doing so and tripped something. Now I have no turn signals and no brake lights. Headlights and tail lights work fine. I checked a couple of fuses under the hood that I believe are for turn signals, according to my manual they are fuses #20 and 22. They aren't getting any power, but the fuses themselves are fine. Is there another fuse somewhere to check? Or something else entirely?

I made the conversion of the regular bulbs to led ( stops, position, turn signals ) but I have fast blinking in turn signals. I know that the led has fewer electric resistance than the regular bulbs so the car takes this like a damaged bulb.
I know two possibilities:
1- A resistance for each one of the led to confuse the system.
2 - Changing the electronic relay
I don't know which one is better. I need a resistance for each bulb? which relay is the appropriate one for this car (there's a lot of references on the internet and I can't find the relay in the hood's car).

I have a 1998 or 1997 Honda Accord and just noticed the other day that my left turn signal was blinking faster than normal. Now I know that this would denote a burnt lightbulb but I got out of my car to see if one wasn't working on my left side. All of my lights seem to be "on" but the left side turn signals are flashing faster than normal. Also I did hit a speed bump at app. 40 mph the other day.
