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 RepliesMy center brake light went out a month ago. Thought it was the bulb so replaced that, still didn't work. Checked the fuse and its not broken so my guess was electrical?
Hasn't come on once that I know of but I was randomly walking behind my truck and the light was on. Truck was off lights were off and key wasn't in the ignition.
Went and turned my truck on and turned the lights on and the cbl stayed on. When I switched my lights off it went out and stayed out.
Now I'm definitely thinking wiring but not sure where to start fixing?
Oh and it's a 1990 F150 XLT
I recently changed out the power boost canister for the brakes on a 1990 f-150 2wd. It was successful but now i have no cruise control. I double checked my plugs, all good. I checked my brake lights, all good. brake pedal seems fine and completely raised when not in use. i looked for a fuse and can't find it for that system, seems odd. it's not in fuse jct under dash, can't find a fuse jct under hood, seems odd also. No check engine light has lit.
View 3 RepliesI have a need for a 12-volt signal to indicate the engine is in start or run mode. I would like to pull this from the engine compartment but I'm not sure what would be the best or easiest way to do this. The 12-volt signal is not used to power anything so it will draw very little current. I have a 94 F150.
View 8 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 RepliesI have a 2006 f150. Both front turn signals do not work. I replaced bulbs still nothing. There back signals do work. They blink really fast.
View 4 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.
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 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.
2003 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???
1994 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 RepliesMy 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 RepliesOkay, my 1986 f150 with a 351w (non-feedback carbed) Has no lights on the cluster, and none of the gauges work (haven't tested the speedo yet, truck is not registered yet).
I also have a minor issue with the turn signals... Fronts work, no rears. The left turn indicator light on the dash does not come on but the right turn one does. All my "primary lights" (markers, tail, headlights) work fine. I have not yet tested the brake lights.
Fuses all look good, truck did have some roof leaks. I've done some research, does this sound like the dreaded voltage regulator issue for the gauges?
My assumption for the left turn indicator light is that there is a replaceable bulb in the dash (probably blown), is that right? Rear signals might be wiring (PO installed his own trailer wiring) or bulbs? haven't gotten that far into it yet...
I 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.
View 2 Replies2001 F-350 diesel. Out of nowhere, I start the truck and there's no turn signals. Fuse is blown so I replace it. It immediately blows. Tail lights work. No turn signal, brake lights, or hazards. I haven't hooked up a trailer or done anything abnormal recently. Only the #1 fuse (20Amp) is blown. Pulled bulbs and they work fine. Inspected wiring under and near lights. NOTHING! Any way to localize a short?

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 RepliesI 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.
My wife drives a 2013 jeep patriot with less than 20k miles on it. The turn signals began behaving eccentrically (beeps at strange intervals, and the right turn signal flashing twice as fast most of the time). We figured out that the right rear brake/turn light was out, so I replaced the bulb. That solved the problems, but on the way I noticed that the widget that the bulb plugs into looks just scorched (see pics). I don't have enough experience with these vehicles to know if this is normal, or if this means more trouble to come.
View 6 RepliesI just bought a hard to start 1990 F250. Per the board, just replaced all 8 glow plugs with Motorcraft. Still wouldn't start (it turns over but will only start if you use either). I attempted to install a new BWD brand (Borg Warner I believe) glow plug connector relay today...I removed the old no problem, but am unsure what wires to plug where....the only connection that I'm sure about is the blue wire that works the WTS feature...it plugs in easily but I don't know if there are other connections that need to be made or not? All the wires run from the posts and into the bottom of the unit.
View 2 RepliesMy car is a 1998 Honda Civic. The left turn signal blinks at double speed when the headlights are off. When the headlights are on, it blinks at half speed. Should I replace the left-sided bulbs? Or the turn signal relay? Or something else? None of the bulbs are out in the front or rear.
One other fact: If the hazards are on with headlight OFF everything blinks in synchrony. If the hazards are on with the headlight ON the front blinkers flash alternating (left-right-left etc).
