Ford F-150 - 1997-2003 :: No Brake Lights But Turn Signals Work
Jan 23, 2017
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 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.

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.

So I lent my santa fe to a buddy to do some hauling, I got it back yesterday and the turn signals and the brake lights don't work...notta. Regular running lights are working without issue, but no turn signals, no hazards, no brakes. Even the "tick, tick, tick" of the turn signal is gone, it's just dead.

I have a 2003 Ford F150 King Ranch which I just bought, I noticed that the turn signals (both right and left) do not work and also the power mirrors are not working.
My 2003 Ford F150 has the 5.4 vortec, 4 x 4, automatic with 200K on it

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.

Every time I step on the brakes, there is a bright spark in fuse #13. My brake lights, turn signals and hazards don't work. At this point my truck isn't drivable.
According to the owner's manual in my truck, says circuit #13 is for "stop lamps, CHMSL/hazard, trailer tow stop lamp, and speed control."
I'm assuming that the hazard part covers the turn signals as well, but I know the cruise control works even when the fuse is blown. I used it last night on the way home (this was before I realized I didn't have brake lights).
So I know I have a short somewhere. The only mods I've done to the lights are aftermarket headlights, but if the fuse only gets blown when I step on the brakes, I don't see what that would have to do with it. Also, the lights have been installed and working for about a month before this started. The only thing that I did around the same time was install the gauges. I ran the power to them from #5, the customer access circuit.
Are there any other "common" areas for this to happen? I already removed the rear brake lights and it didn't work. I am quickly running out of 20A mini fuses.

All of this happened at the same time so has to be related. The a/c system has no power, the brake lights and turn signals don't work, windows wont work, air bag light on. However, the park lights, head lights and hazards work fine. Starts and runs fine. All fuses check out ok. New battery as well.

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.

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?

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've got a 2001 f150 supercrew 4x4 with the 4.6. I plugged in trailer lights and now I have no brake, turn signal, or hazard lights. I've checked fuses and none are blown.

I have 1999 Ford F-150 xlt and on the passenger side the brake and turn signal don't work but reverse light does. On the driver's side, everything works so I switch bulbs and outlets and it still doesn't work but two of the wires for trailer hook up and cut. I was wondering if that had anything to do with that.

My service advancetrac light comes on about once a month, seems random but when it does the turn signals will not work, you have to hold indicator in place for signals to work-not to safe. My local dealer has not been able to fix issue...

I have checked all wires for krosion and fuse's are good so confused! Just put brand new tail lights bulbs in! The top one comes on as a running light but nothing else works. I also checked under hood fuses too!
1.Only Hazard light that works is on the Right Front passenger side.
2 Drivers side Brake Light & Turn Signal Doesn't Work. But passenger works fine! Left turn signal is out and blinks really fast!
3.Passenger Side Overhead Outside Light on cab is out . Okay that's probably just a bulb!

I'm having problems with my front marker lights. The turn signals work but when I turn on the parking lights or headlights they don't work. They only work with the turn signals. And I can't get the front side marker lights to come on. I've tried everything...

I was using a 2004 Heritage F150 and when I connected a trailer to it something got fried. I lost both my turn signals and brake lights. The trailer worked fine on my friends truck so I don't think the issue was there but with the 4-pin round connector that was on the truck.
I found two 10A fuses blown under the hood and replaced them but that didn't work. They were in slots 19 and 20 and are listed as the camper/trailer adapter fuses. The running lights still work. The interior turn signal arrows don't even light up or anything when the turn signal is activated.
