Ford Wiring/Electrical :: 1990 F150 - Center Brake Light Went Out
May 28, 2014
My 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

Why the parking brake light in my dash stays on, 2004 F150. Fluid in master cylinder is full, has no signs of leaks anywhere.

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?

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.

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?

I have a 1999 Ford F150 6 cyl. 4.2, 2 WD with 160,000 miles. Replaced the battery May 2010.
Today battery light came on. Battery gauge did not look like it was discharging. Had battery checked they said it was a little low but OK. Then they continued test and tried to check alternator, test stopped and they said something wrong with alternator most likely.
I took alternator out and had it bench tested. They said it was OK, putting out 98 amp on 95 amp alternator. They said check wires, grounds, harness, connections. Checked connections and wires as much as possible, reinstalled alternator, light still on.
Have not checked fuses yet. Was told to start vehicle, disconnect positive battery cable and if engine continued to run alternator was good, if cut off alternator was bad and to replace. Should I try this and is it true?
What is the part on the fire wall that is between the alternator and the battery that the wire connection runs through? Can it be bench tested/checked?

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.

I've searched all over and can't seem to find the answer. When I pull the tail light out of my 12 F150 there is a blue/wht wire and a black wire going to the back up light. I assume the blue wire is the positive and black is the ground. Is that correct?

I have an 06 F150 XLT and lately the map lights blink when starting and driving. This does not occur every time but it sure is a problem when driving at night. What is causing this and hopefully a minor repair.

I've been trying to trace down a issue with the airbag warning light flashing. The seatbelt light is flashing also. The airbag code is 53. If i search it i get the front crash sensor..I replaced it with a new sensor and pigtail. Other than that the search leads me to believe it could be anything.
I've checked and clean every connection that i could find. I haven't removed the center console yet to check the module. I did buy the truck last fall as a winter/work truck. The issue started a couple of months after i started driving it. Not sure if the module would just go bad.

I 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.

Start out, drive about 20 minutes, get on the Interstate and the battery light comes on 2008 F 150 5.4L 4X4 - 57K miles..... get to my destination, went about 20 miles, turn around to come home, without turning the truck off because of the battery light being on and I notice the charging gauge drifting down to the left, get back on the Interstate and the wipers are slowing down and lights on the dash are dimming.....go around 15 more minutes I lose all lights on dash, wipers, defroster everything, charging gauge is now pegged all the way down to the left and the truck is starting to act up running like crap so I barely make it off the Interstate and call a flatbed, I guess I was about an hour into the trip ..... battery is only about a year old and it started fine that morning and the day before when it was about 12 degrees ...... dealership had the truck, just gave me a call and said they can't find anything ?? ..... never a days problem since I bought it new in late 07' ....

Okay, 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...

Looking for a wiring diagram for a F-150 XLT LARIAT 5.8L 4BBL, all the books I have looked at show the wiring for this year with fuel injection and this truck came with a 351W with a Holley 600 4BBL, I have a few wire's in the engine compartment that melted away all the insulation, they are located close to where the harness passes the firewall before the ignition module. Is this a common problem on old models ?. Need a clear copy of the correct diagram for a f-150 1987 with carburetor, how I can get a copy so I can fix this problem before it gets worse.

Problem with my 2006 F150 5.4 4x4... Voltmeter spikes, battery light comes on, grinding noise as 4x4 engages on its own then everything returns to normal after about 60 seconds. Took to Ford who replaced the alternator and battery, still doing it so they replaced the alternator again...they checked the wiring and replaced some other misc parts and don't know what the problem is. The problem occurs once every few days, after only a few minutes or after a few hours, completely random.

I have a 1962 ford falcon ranchero. The driver side brake light, goes out when brake pressure is applied, but is on when lights are fully on, but even then brake pressure is applied and goes out. Right brake light is fine. And turn signal on right works. But driver side back light goes out when brake pressure is put on and when turn signal is put for left side. Right makes a turn noise left side doesn't. I recently replaced the turn signal switch. So its brand new. But older wires every where else. No cuts anywhere on wires. Fine. And replaced the bulb also.

2010 F-250 14,000 miles, gas engine with Knapheide utility bed. Tilt wheel has been kept in the up position from day 1.
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.

I have a 1990 F-350 7.3 lariat crew cab. The tail lights fail to work but all the turn signal and brake lights work. I changed the light switch located to the left of the steering wheel but that didn't solve the problem. all the fuses under the dash appear to be ok to. Is there another fuse for just the tail lights.

My truck is a 1990 F-150 with the 351. I was replacing the spark plugs last night, got it all wrapped up and everything squared away, and after firing the truck up I noticed a ticking noise. It was not there before I replaced the old plugs, and it is not at all loud. I can hardly hear it with the hood closed. It appears to be coming from the driver's side of the engine. It does not misfire when its idling, and it revs smoothly. However, while driving it is noticeably choppy and feels sluggish.
Any thoughts on what it could be? I used dielectric grease on the boots, but I did not replace the plug wires themselves, or the distributor cap. I am probably going to replace the plug wires today though, because the plugs I took out were not in good condition and its been a bit too long since I replaced them last. Its also worth noting this engine is less than years old. This is a frustrating problem because I've replaced the spark plugs on her before, so I'm not quite sure what I did wrong this time.

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.

Here's the breakdown. I have a '95 Ford F150 that I bought the previous year and it has been nothing but a problem. The most recent problem is the attempt to turn on the headlights. I will pull the plunger to turn on the headlights but I will only get the parking lights and when attempting to turn on the high beams I still get nothing. The only way that I get any sort of lighting is if I pull on the turning stick (almost like doing a manual override on a tripped wall plugin). Now here's the kicker. I still have parking lights, brake, tail, cab, and dash lights. Winter in quickly approaching and the nights are already getting dark, pretty soon the days will be just as dark.
