Ok so my fire station has a 2003 f550 rescue truck with a rescue body with the round tail lights, we recently upgraded them to the LED ones that are much brighter but of course it flashes at the speed of sound. The question I have is:
1. the relay {flasher} is located on the driver side inner fender? I think....
2. does the same EP-27 relay/flasher fix the problem?
My neighbors 02 250 6.8l the turn signal/hazard relay is clicking with key off, sounds exactly like a turn signal when truck is off and switches are not engaged. Here's the weird thing, if you hit the brakes the relay stops clicking, if you engage the turn signal or the hazards the lights on the dash are in time with the relay as it should be, but when the turn signal switch or hazards are turned off the relay keeps clicking except when you hit the brakes. Also the turn signal will work with ignition off, if you pull the relay out the turn signals and hazards are inoperable but the brake lights still work. I swapped in a new relay and same thing...
View 8 RepliesI am looking for the location of the fuel pump relay for my 1999 Ford F550 V10 4WD Gas truck.
I have replaced the fuel filter and fuel pump. When the key is turned the pump gets juice and 2 seconds later is not getting juice. No lines are coming into it, so it's not getting up to pressure and shutting off.
I've done a bunch of searches and can't really find much. The turn signal in my 03 SD doesn't work, and the back side is loose, probably a broken tab. I have cranked the mirror up, down, right and left, popped the tabs loose yet it feels like I'm missing one or a screw. I read that I may have to "Pop" my mirror off to get to stuff. The dealer said I have to buy a complete mirror assembly just to change a freaking bulb on an 03?
View 1 RepliesRecently got a 2003 f 250 6.0 that has had a little work done on it. Absolutely love it with 1 exception. When I turn on the ac or heat It blows a 10 amp fuse that goes to the blower relay. It was occasionally now it's all the time.Blower ok, fan speed resistor ok. What or where to look.
View 8 RepliesI 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!
View 7 RepliesJust got done with a ball joint replacement on my 2003 F550, everything went together great, just as it should. Until I got to the drivers side hub lock.
I have Mile Marker 449s/s manual hubs. Turn from free to lock and theres this loud clicking sound about halfway to LOCK (passenger side doesn't do this). Hub will stay locked for about 2 rotations, then it unlocks and makes a clicking sound. You cannot turn the hub back to FREE, it gets halfway and stops. I tried forcing it and broke the spring fingers inside. Have a new set on order.
Is this a locking hub issue or an assembly error? I was going to take these steps.
- Take passenger side hub lock off and see if it operates normally or same on drivers side.
- If same, remove axle and re-seat/re-assemble everything again
Anything to specifically check? All the parts went back in, washers were in correct order, outer snap ring is in groove.
I went to have the code read, and it was no signal from the rear ABS speed sensor. I replaced the sensor, and the light is still on. Also my speedo is off a bit. It is reading about 7-10 miles an hour faster than what it should. The mechanic can't seem to find the issue. I have a 06 F250, Powerstroke.
View 2 RepliesI picked up a set of harley davidson look-a-like headlights online for my 05. I go to install them and when I tighten them up it causes the turn signal bulbs to push in towards the fender on both. I put my hand back there and it feels like the bulb socket is being forced against the header panel assembly. Am I missing something?
View 2 RepliesI have a 2003 F550 6L diesel flatbed truck. Last week, the overdrive button would activate by itself. I'm assuming there was a loose wire so I taped the button to keep the overdrive off. Two days later, the overdrive came on while the button was pressed in and then smoke came out of the steering column/lever area. I pulled over and turned off the truck. The smoke stopped after 10 seconds and I restarted the truck. The overdrive light/functionality no longer worked and the instrument cluster also wasn't working.
The next day I was driving, and the truck died at a stoplight. I got it towed home, and opened the steering column and noticed that the overdrive button wire had burned. I removed the harness clip and charged the batteries. It started but the instrument cluster still didn't work. 2 minutes later the truck died. I replaced the alternator but still it won't charge the batteries. The truck dies 2 minutes after getting a battery boost to start the truck. The instrument cluster also doesn't work. What could be causing this issue?
I have an 02 F250 6.8 with 51,000 miles on it. I recently replaced the battery about a week ago, and only actually drove it yesterday for the first time since replacing the battery. I drove it about 25 miles, parked, and when I went to restart, it wouldn't. The starter doesn't crank, so I mean its not a cranking issue as in cranking, and not starting. It only clicks at the relay when turning the key. It acts like when you try to use a wrong chip coded key.
All of the dash lights came on, and I can hear the relay clicking, but that's it. I swapped the relays around, and no luck. If I let it sit a while, about an hour, it will fire right up. The battery cables are tight and free of corrosion. I am curious, since I just put in a new battery, could this be the culprit? Why will it start fine cold, but not hot? I have NEVER had an issue with this truck until now.
My truck is a 1999 F-250 Super Duty 7.3 diesel. My left turn signal is fine. My right turn signal is going fast. The rear blinker lights up, but the front does not. So... no brainer... change the front bulb. I did. Twice. Sylvania 3157. It did not fix the problem...
View 11 RepliesI have a 2001 for f250 with the electronic shift on the fly and when I turn the switch to put it in 4hi or low nothing happens I don't hear a click and the lights don't come on but the 4wd light works it comes on when I first start the truck and I put different relays in that we're good and still nothing I tested the the relay box itself for power and there wasn't any.
I used the truck last year for plowing and it worked sometimes it wouldn't go In or come out but after a few tries it would end up working but I've tried everything I could think of I'm starting to think it's something electrical because the relay box isn't getting power to it but idk if a vacuum leak would do that or a bad transfer case motor or iwe solenoid or if it's something more like a broken wire some where.
Buddy has a problem on his '03 F-450 cab and chassis. When he turns on a turn signal, everything is OK...but it goes out when he applies the brakes. Also, the brake failure light is lit up on the dash, despite the brakes being fine. These problems happened at the same time. I'm think a ground, but not sure where to look.
View 5 RepliesI replaced the bulb and it's still not blinking and doing the quick blink on the front and mirror bulbs.
The bulb turns on when on parking lights; it just won't blink.
2012 F250 left turn signal on all the time no right turn signal.
View 2 RepliesThe truck I'm working on is a 2003 f550 with a 6.0, and 382000 kilometers. My service truck died on me couple days ago, while running. As I rolled to a stop, I noticed that my temp gauge on the dash dropped to cold. (Truck was hot). Tried starting, and I have a crank, no start situation.
After towing it to my shop at work, I hooked it up to my scanner, and found that the pcm will not communicate with the scanner (otc genisis). I have no injector buzz with key on, wait to start light comes on for an abnormally long time. I have 48.3 volts on the ficm,(4 screw), and haven't been able to find any chafed wires as of yet.
I'm still fighting tow harness problems on my '01 F 250. I started by replacing the 7-way pig tail with a new one which didn't work. Then I undid all the butchering of the harness that was done previously. The factory harness had scotch locks all over it that were used to splice in a 6-way and a 7-way into the bed. I liquid taped all the nicks in the wires. Then I checked for power at the factory harness end where the pigtail plugs in. I have park/running lights, and one of the ports flashes for the left turn signal/flashers/stop lamps. I got rained on before I could check further up the wire. If I have no power to the wire further up is there another place to check?
View 2 RepliesWhile I know this has been covered before, I could not find anything pertinent to 2011-2015 model years.
So, I changed my turn signals to LEDs, and now I have the fast-blink behavior. I realize this is because of the significantly decreased amperage and resistance of the LED modules. I did a similar mod on my 2007, and simply found a replacement low-current blinker relay (on eBay, I think), and replaced it (it was physically located behind the extra small glove box near the middle of the dash.
My questions are, 1) for a 2015, should I use the same method of replacing the blinker relay? 2) Any brand and model that will work for this application and/or where one can be purchased and 3) Where is that relay located on the 2015 model? If not, should resistors be used?
I have never liked that the headlights are below the turn signals on the newer super duties. Has anyone swapped the positions so the headlights are on top? Will be ordering a 2016 next week and this would be one mod I would like to do. Not having the truck yet, I have not been able to do any investigation on what this would take or if it is even possible.
