Ford 7.3L Power Stroke (1999-2003) :: Red Door Open Light Started Staying On

So my red door open light started staying on. Along with all the lights associated with the doors being opened. The lights don't always come on, but the dash lights stays. As a quick fix I just popped the bulbs out and went on my way. Tried lubing the doors. That didn't work. I started noticing it seemed to be related to when I was slowing down or turning.

I thought maybe it's my passenger leaning on the door around the turns. So I inspected all the doors, they latch fine and don't feel like they're open. Last night I was riding by myself, and I realized that it wasn't anyone leaning on the door. When I would slow down, at the same spot. I would hear a click and the lights by the doors would come on, as well as the light on the back of the cab over the bed.

It did it every time the whole way home. It was approx. 16-18 mph when it would click. It was the same spot each time but I couldn't really nail the exact speed and watch for deer. I originally thought I'd just replace the sensors in the doors, but idk if that'll work anymore since it seems to be affected by other factors.

Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - Airbag Light Is Staying On / Code 25

Just bought a 2002 F-250 4x4 Off-Road Crew Cab 7.3L and the airbag light is staying on. I have found out after the fact that the truck has been previously involved in a front end collision. The damage was to the passenger side front. I turn the ignition on, the airbag light will come on solid (just like all the rest, with the exception of the 4x4 and 4x4 low) then go out. Then it flashes slowly 2x then 5x, then goes out for a bit then repeats a few times before staying on. This tells me I am getting a code of 25. I have searched with no luck to narrow this issue down. Everything mechanically works, cruise, horn, etc. The only thing I can find wrong is when I engage the 4-wheel drive (floor shifter) the indicator lights do not illuminate in the instrument cluster. Neither the 4x4 nor the 4x4 low. I am unfamiliar with this truck, so I don't know where to began searching. I cant afford to take it to a dealer and I have children in the truck quite often, so I would like to remedy this very quickly.

Ford 7.3L Power Stroke (1999-2003) :: Tach Quit Working - Warning Lights Staying

Well today the tach was not working at all and the check gauge, check engine and glow plug lights are staying on. Truck runs and starts great, everything else seems to work except the trans temp gauge. Did a search for the GEM and could not find anything that indicates the GEM controls the tach and warning lights.

Ford 6.0L Power Stroke Diesel :: Headlights On But Switch Is Off

I just happened to look out the window of the house and see that the headlights on my truck were on. However, they were turned off from inside. When I stepped on to the porch, I immediately smelled something electric smoking. I tried turning off the lights by switching the lights from on to off, but that didn't effect the lights at all. There was a humming close to the turbo and the smoke seemed to be in the cabin more so than under the hood. I've had this truck for most of its life and it's never had an electrical issue. What it could be?

Ford 7.3L Power Stroke (1999-2003) :: Power Come On But Won't Start - Broken Ignition Switch?

Went to start 'er up, key spun forwards, power came on but no start, no click, nada. Turn key back and power stayed on, back forward and no resistance whatsoever power stayed on. Took screwdriver, jumped starter relay and viola away we go. Get home, get cylinder out of hole and the tip is broken off down in the column. BTW, had to disconnect batteries to shut it off. I drilled hole in the tip still in the column, insert screw and no come out. Must need to be turned somehow first I'm thinking.

Ford 7.3L Power Stroke (1999-2003) :: OD Switch Not Working / No First Or Second Gear

I have an early 99 f350. when i got the truck the OD switch(maybe light too) didn't work. i ran it for about 1k mi. yesterday i left work to come home and i didn't have 1st or 2nd gear but still had 3rd and od. the only way to get 2nd is to manually put it in 2nd gear. 1st seems to be nowhere around.

I do not have a code reader and wont for at least a month or so. I did install a simple ts6 in it, that's about all i did with the truck.

Ford 7.3L Power Stroke (1999-2003) :: How To Switch Out Of 4WD When ESOF Is Broke

My ESOF crapped the bed as the truck was stuck in 4 Low. I took the transfer case motor switch off to access the gear underneath it.

I'm able to get vise-grips on it but it only turns clockwise. It keeps turning to a point it won't turn anymore and, if I let go, it will switch back to its original position.

I can do without 4WD until I get ESOF fixed, but is there a trick to manually changing it to 2WD?

Ford 7.3L Power Stroke (1999-2003) :: Sticky Ignition Switch

I seem to have a glitch in my ignition switch box or column. Most likely in the column itself. Whats the recommended course of action here? Contact cleaner and then white lithium grease in the column? Can WLG be used on the ignition switch box itself, that's bolted under the column?

Ford 7.3L Power Stroke (1999-2003) :: Almost Died When Headlights Turned On?

I have a 2003 F350 SD FWD Dually With 4.10 Axle Ratio. I'm looking for some front rotors and pads and I'm looking for recommendations. I tow a 44' Goose neck racing trailer on a regular basis so I dont want autozone crap rotors that are going to warp in a few thousand miles. I was on rockauto.com, they have Wagner, Bendix, Motocraft, Powerstop, etc etc. I thought maybe those Powerstop drilled and slotted looked interesting, but I dont know much about them.

Ford 7.3L Power Stroke (1999-2003) :: Driver Window Switch Not Working?

New to these trucks so a quick question on the window switch controls. I put power to the truck for the first time in about 8 years. First thing i wanted to do is see if the power windows worked. Everything went down very nicely but getting them back up was a no go from the driver seat. They all worked well seperatly but not from the pilots seat? Is it a typical issue with these trucks? When rocking the switch I can hear a relay under the dash panel close to where the access panel for the fuses. Mirrors work as well as do the locks. I pryed up the switch panel and un plugged it and reinstalled it with no luck. As it is I cant get the driver side window up or the passanger window up from the driver side?

Ford 7.3L Power Stroke (1999-2003) :: Both Headlights Suddenly Stopped Working

Well a few days ago I pulled up to a gas station on my way to work for some coffee and since I leave for work before 6:30 AM my headlights were on. Well only the running lights were working. Well I shrug it off and later that night I come to the realization that both headlights weren't working. I tried the high beams and they do work. I also pulled both bulbs and both the filaments on each bulb seemed to be intact. What could cause this? I checked fuses 9 and 11 under the hood and they were both fine. I'm kinda at a loss right now.

I know this is going to sounds lame, my wife can't turn them, they have cover over it that has to be unscrewed to get at 'em. It would be nice to shift in and out "on the fly" as weather condition change.

Is it a difficult change?

Ford 7.3L Power Stroke (1999-2003) :: Low Batteries - Headlights Dimming / Brightening With Acceleration

So I have noticed that my Batteries have been low each time my truck sits. Also my headlights have been dimming/brightening with acceleration. So I thought my Batteries were going bad. So I did some tests, I let my truck sit over night and tested the Batteries before starting they both were around 11 volts. @ idle no load 12.3, with load 11.7. @ 1500 RPM 14volts. With this I went to autozone and had the Batteries tested and the guy said that they are good but need to be charged and that the alternator was not charging right causing the low Batteries. The Batteries are about 3 years old. So now Im not sure what to do.

Ford 7.3L Power Stroke (1999-2003) :: Buzzing Sound When Flipping To Switch To Signal Turning

After disassembling what felt like the whole front end of the truck, I finally gain access to the danged thing. Mine has been acting up intermittently for about year and half I guess. When flipping to switch to signal turning, it started making a buzzing sound. At first it was doing it most of the time. Then it cleared up and started working right for several months, then act up, the act right. Well, now it makes the buzzing noise more often than not so i decided to address it. I went to Oreilly, they didn't have one, but told me the part number.

I went across the street to Autozone, that had one on the shelf that was same part number as Oreilly. I put it in and when flipping the switch, the relay does it tick tock sounds like its working, except for there is no indication on the dash cluster that its working, nor are the actual lights working. I swap back to original and buzzing, put in new one and tick tock but no lights. Whats the deal? Is this one of those things that you have to go back to Ford? Or maybe i got a bum relay from parts house and should exchange for another to see if it works?
