I just bought an 05 F250 XLT. I noticed tonight that the rear turn signals and brake lights dont 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.

85 f150. My driver side brake light and turn signal in the back quit working. The tail light works tho which is a different filament. The bulb is good and I changed the flasher relay...the circle thing in the fuse panel. Everything else works just fine. looking for a starting point.
View 7 RepliesTurn signals quit working on my 2006 E-150. Swapped out the relay under the dash and it did nothing. Also noticed the brake lights aren't working. The headlights and taillight a are working. I pulled the fuses under dash for the lights and they tested ok. I did notice the flasher relay was making clicking sounds intermittently even when not touching anything.
View 3 RepliesI have a unique problem with my newly acquired 71 F250. The left brake does illuminate when the brake is pressed but when the right turn signal if activated the left brake light does come on. The left flasher light also does not work. All other rear ligh function are normal. I am assuming I have a short or a wiring issue just wanted to know if there was any common item that might be know about this topic. The bulbs are all new. The reverse lights do not work either but pretty for sure its unrelated.

The problem:
No rear brake lights.
No high mount brake light.
No rear turn signals.
No rear hazard flashing lights.
All trailer lights work.
All other truck lights work.
Things checked: Fuses all OK. Visual inspection of multi-function switch. Looks clean. Brake switch at brake pedal has power on one wire. Jumpered the other wire-no brake lights.
I need to haul my trailer and am nervous when I see a Savannah, GA metro police car.
Swapping the 08 mirrors onto older trucks. Which wire I should splice into in the door sill for the right turn signals?
I have an 08, with the tow mirrors/turn signals integrated. On the passenger side, the turn signal does not work. I'm not getting power at the plug.
I traced the wire colors from the headlight and taillight turn lamps and tried splicing into the same colored wires under the passenger door sill. This didn't work (I did get it to work on park lamps though, just not the turn signal). I can't find wiring diagrams.
I have no left rear signal or brake lights. The right side works fine and both left/right tail lights work fine, just no left brake or signal. I checked for broken wires and can not find anything. 1992 Ford E50 7.5L.

Last week wife's right rear turn signal/brake light stopped working. The left one flashes normally. The right tail light works fine which is a different bulb. I tried changing bulbs (didn't work).....tried a new socket with new and old bulb (didn't work). Could it be a relay? Or not relay as they would be both out (left and right)?
I looked at my trailering wiring plug down by bumper and the white wire with green stripe looks split a little towards the end. Could it be a bad ground or short in that wire? Would the trailering wiring have anything to do with it? I was going to try to replace the relay if I could find it, what is the part number for it.
I am working on friends 2011 Ford F450 Diesel He has lost Brake Lights and Turn Signal/Hazards.
Turn signals work in front of truck. Running lights are working fine.
Same goes when trailer is connected on truck. What could be the problem.
Need a wire diagram. I have a connector in the cab that has red,blue,lt green,white wires. It's causing my brake lights not to work. I need a wire diagram that shows were they go. I can't find these wires in my Haynes manual.
View 3 RepliesI have a 2006 F150 and the left rear turn signal and brake light has quit working. Also the license plate lights do not work. The cruise will disconnect when signalling a left turn. I have checked fuses and bulbs and the wiring/connector at the multifunction switch with no luck.
View 2 Replies1994 Econoline E350. All the other lights work but on the front right the turn signal light flashes but the Hazard lite will not flash. I check for power at the wire at the light and there is none.
View 6 RepliesI have a 72 F250. When I put the left turn signal on and apply the brakes, the signal stops blinking. I checked the bulb and it was fine. What is the likely cause?
View 2 Replies1991 F250 Supercab Diesel 4X4. I made a mistake while wiring up my trailer lights and ended up grounding out my brake controller, frying it. Along with that, I popped a couple fuses as well (1, 5 and 9 I believe). Replaced all fuses and got my signals (F/R) back at least.
Here's what's NOT working/messed up:
*Brake Lights
*Cruise Control
*Rear ABS light comes on a few minutes after driving.
*Front hazards work, not rear. When I apply the brake, the hazards pause in the on position.
I've tested the brake switch on the brake pedal (Green/Red and Green) and it works properly. So, current is obviously not reaching the rear brake lights.
Another note. The truck is wired with a 7 pin plug in the bed for a goose neck trailer. It also was wired to a 6 pin on the bumper. I replaced the 6 pin with a 7. The signal/brake pins on the plugs (both) and also not receiving power. What's the next thing to check?
My brake lights, turn signals, and flasher are not working in my truck. Is it a fuse and what fuse? Could it be a relay?
View 2 RepliesDad 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.
View 6 RepliesLong story short, my truck's front turn signals and rear turn signals/tail lights won't work. I am thinking that the relay is burnt. Whenever I look in the manual I can't seem to find the location for this relay. Is is built into the flasher?
Also, I am just assuming because the rear turn signals and tail lights are the same bulb that fixing this should clear up both problems. Am I right in thinking that?
I have already checked all of the fuses. Also, the Hazards don't work either.
I have a 1990 f-150 that periodically (and rapidly) blows the fuse for the turn signals. The brake/tail lights continue to work, but just the turn signals quits. Looking for a schematic of those systems?
View 1 Replies2003 SCrew, 5.4, auto, 4x4.... Yesterday my left turn signal started flashing fast; checked and the front was not flashing. Picked up a new bulb, changed it, didn't fix anything.
I've tried:
-tilt wheel up/down in all settings-no change
-checked the wiring at the top of the column; still good and solid.
-swapped the bulbs left to right and vice versa-no change.
-swapped the sockets left to right and vice versa-no change.
Other info:
-the left front is the only one not flashing with hazards on.
-all original equipment, except I removed the stock side mirrors (w/signal) and installed manual trailer towing mirrors, but that was 2 or 3 years ago.
-the dash indicator light for left turn (arrow) does not come on at all.
-last trailer tow was over a month ago and all was good.
I ran out of daylight last night and at work now so I would like know which Fuse, Flasher, Relay, etc., I should check/replace and where to find them on the truck; under the hood (1st or 2nd stack of the fuse blocks); under the dash above the pedals; steering column???
I have a 1997 F150 5.4L 2wd long bed w/ tow package.
Right (passenger) turn signal/brake light is not illuminating. The tail light on the right side does illuminate when headlights are on. (Same Bulb) All other lights are functioning properly.
When the MFS is in the right turn position the right arrow on the dash flashes and clicks faster than normal.
This happened about a month ago and it turned out to be a blown fuse. The fuse was for the trailer lighting and right turn/stop light, found in the small fuse box under the hood that only holds 2 fuses. Problem solved temporarily...
Now the issue is back, Here are some things I've tried so far:
Replaced the fuse again; Turns out the fuse didn't blow this time, but I tried a new one anyway.
Cleaned the ground for the rear light wiring harness.
Replaced the bulb.
Replaced the relay.
Checked continuity on multi-function switch, right turn position reads 2.8 ohms IIRC
Repaired pin #5 on the multi-function switch wiring connector (wire backed out, right turn related)
Replaced the bulb socket.
Inspected the wiring for broken insulation/exposed wires from that socket to under the hood, didn't find anything exposed. All wires are still in the loom.
I replaced this wiring harness and wiring looms about 6 months ago because the previous owner had done a hideous splice job for unknown reasons, so it should be ok. Should I get a new multi-function switch, or try something else? If the switch doesn't work what's the next step?
