Ford Super Duty (1999-2016) :: 2002 F250 - Turn Signal Malfunction Caused By Brake Light Circuit
Jan 4, 2014
I'm having a turn signal issue with my '02 F-250 that started this morning out of the blue. Seems that when the signal switch is set for a right hand turn and the brakes are applied, the signal will then become solid, not flash, and then blow the fuse. Evidently something with the brake light circuit is overloading the turn signal circuit and not canceling when the turn signal is activated.
Here are a couple of things I have tried to narrow down the culprit.
1) Left turn signal works fine regardless if the brake lights are operating.
2) Brake light circuit operates fine by itself.
3) Right turn signal works fine but there seems to be a back-feed of power causing the center third brake light as well as the left side rear brake light to flash in unison. If brake lights are then activated, the flash stops and becomes constant thus blowing the fuse.
4) Emergency Hazard lights work perfect but the center third brake light again flashes as well which reverts back to some type of back-feed of power. Also, if brake lights come on, flashing turns to constant light and then blows the fuse again.
I guess my question is,. does this seem like the multi-function switch needs replacing or could this be a relay issue of some sort? I don' think its a ground issue simply because the left turn signal circuit as well as the center brake light circuit are both being breached when the right turn signal is activated. Your thoughts?

I have an 2001 Ford F250 V10 CCSB. I installed 3157 LED Brake//Turn light. Now when I turn in my left turn signal it blinks fast which I can live with that but it would be nice if it blinked at the regular phase. Here my big problem. When I turn on my right turn signal there's a loud squeal in the cab of my truck. !!!

I did some reading on here this morning and ended up at 1A Auto looking for mirrors. I want to make sure I get the correct thing before ordering. I have a '04 250 with factory tow mirrors that are power mirror and turn signal/clearance light. I want to upgrade to the '08 style. Which of these would work? I would think either, but I'm not sure about the wiring harness?

Parking brake light stays doesn't come on when the parking brake is engaged. The light DOES come on when starting the vehicle and the gauge cluster cycles through its start up procedure. Couldn't find a fuse that would fix my issue...does one exist?
Truck is an '02 F250 w/ 7.3TD and 6 speed manual.

Exactly where that part is, pictures would be useful. Pretty much just had my whole dash apart with no luck. Switched to leds, and can't stand hyper flash like I thought I could. Trying to pull it to make sure I order the right part to correct it.

2013 f-250 crew cab short box, 6.2 gas with 48k miles. Right rear turn signal does not work...SOMETIMES. I took the brake light assembly off...bulb is good, turned on signal and the bulb will flash so I put it back together then drove a couple miles and then signal quits working again. I can't find any loose/corroded/bad wires at the bulb socket and I can't get the bulb to quit working when I have taillight assembly apart, (trying to replicate failure). There are never any blown fuses either.

I have a 2003 F250 Lariat with the OEM power mirrors with the turn signal on them. I let someone drive my truck and they hit something with the mirror and broke the plastic lens. The mirror housing itself is fine. I can't find just that lens anywhere!

02 f250 SD...I need to change the front corner turn signal bulb... How the hell do I get to it? I see the grey plug that I need to take off in between the bottom of the light and bumper but have no clue how to get to it..and what is the bulb number?

2001 F250. I have had issues on other trucks where you get a funny-acting speedometer with a code that comes up as VSS (sensor on top of the rear differential)....And it shifted exact same way.
My new truck speedometer is totally fine and the ABS is on with codes:
C1158 Left front speed sensor coherency malfunction
C1155 Left front speed sensor input circuit malfunction
Shifts about the same way on the trucks with bad VSS.
Question is will a bad front speed sensor affect the way the trans shifts? Doesn't happen all the time. If you go slow it shifts smooth. If you pull off fast a barely noticeable jerk from 1-2 and 2-3....

2013 F250 XL with factory towing package.
My camper and boat trailer do not have turning signal or brake lights when plugged into the round seven pin trailer connector. I have tried both the connector in the bed and under the bumper. I've also connected the trailers to other trucks and the lights work fine so I know the problem is in my truck.

The other day I got in my truck and started down the driveway when I realized I had no brakes, I slowly backed up and parked it. I haven't driven the truck for approx. 2 weeks and it seemed fine then. The master cylinder is full, there are no signs of leakage from wheel cylinders or lines. Today I unscrewed the left front zert and no fluid came out. My pedal goes all the way to the floor.... Whats going on, and if its a easy fix?

I have a 2002 Ford F250 Superduty with a 7.3 diesel. Brakes started sticking on it. I replaced all the calipers cause the boots were starting to crack but not leaking. All four brakes are still sticking. I can drive a little ways and then the brake peddle feels funny and they start dragging all four. I can loosen the bleeder and brake fluid will spray out and release the brakes for awhile.

Battery tested good, tried jumping it as well with cables and with portable pack.
I hear two clicks under the hood (NOT a continuous type click you hear when the battery is dead). The first seems to be up near the passenger fender well when the key is turn to the start position, the second click seems to be down under the motor near the passenger side (near the starter I assume, couldn't tell very well) when the key is RELEASED from the start position. The motor doesn't budge, I don't see any belts flinch or pulleys move to indicate that the starter is engaging. I don't hear anything that sounds like a starter engaging to me.
If not, where the starter solenoid is on this thing? is it separate like the other older ford's I've owned or is it now on the starter? Is there any fuse-able links that could cause this? Wiring diagram? Is there a way to jump the solenoid like in the old school days (e.g. with a screwdriver or wrench)? would like to get this home without towing it or fixing what is really wrong with it in the parking lot.
It's in negative to single digit temps here in Indy now, I fired it up in the morning in negative temps, drove it work. Came out to go home, and now this. So something happened between this morning and now and it's not the battery.

Today I was going to launch my new boat and when I backed down the ramp, the brake went to the floor almost sinking the truck. Long story short, the brake line that runs along the frame to the rear brakes rusted through at a bend that I couldn't see. Seems the line is about 8 feet long. What I'd like to know is can I replace it without dropping the fuel tank which of course I just filled yesterday and can I obtain one at a ford dealer or will I have to order one. My truck is my only transportation.

Truck is an 02 F250 Automatic 4X4, 7.3 PSD.
Cruise control will turn on, will sometimes set speed and sometimes will not. If it does set and work it may kick off at any second or it may run fine. I have noticed it seems to kick off mainly after going over a slight bump in the highway or it may just kick off for the hell of it. Truck has 50,000 miles on it, I bought it new. Also having trouble with the throttle position sensor, it seems to have a "dead spot" at about 58 mph that shows up when I romp down on the pedal to pass on 2 lane roads. Can these two symptoms be related? Both are very aggravating. FWIW it does have the power adjust pedals. Truck is 100% stock, no power chips or other upgrades.

I have a 2002 F250, 5.4 extended cab 4x4. Factory lights. I have no turn signals. They were working just fine and without turning off the truck, all 4 corners quit working at the same time, as far as I know. The indicator lights on the instrument cluster don't work. I have checked/replaced all fuses. Replaced the switch lever and the blinker relay behind the dash. The hazards do work and always have. It might be coincidence but I believe the back-up lights quit working at the same time.

My 2002 F-250 v-10 sat for over a month with me in the hospital for spinal reconstructive surgery. Battery was dead but has been charged and tested as good. The truck cranks strong but will not turnover. I am unable to do other diagnosis, what might be the problem.

I have a 2002 F250 7.3L and it wont start. Its been sitting for the past few days in the cold because the batteries were shot but was plugged in the whole time. I replaced the batteries today and even poured diesel 911 5 hours before trying to start it in case the fuel was gelled. It cranks fine but just wont turn over.

I have a 2006 F250 Superduty 4x4 that the brake lights hazards and turn signals have stopped working in the rear.. The middle cab brake light does not work either.. The running lights do work as well as the turn signal and all lights in the front.. I also checked the trailer plugs and both work for running brake and signal lights.. I have checked all fuses under the hood as well under the dash with a test light and i have nothing blown.. I have replaced the Brake switch as well as the flasher module under the dash and picked up a new multifunction switch (Turn signal/hazard) and that didn't work either.. I'm stumped at this point.. I have not checked the bulbs yet but wouldn't think they would all blow at the same time.. (will do this next)..
