Ford 7.3L Power Stroke (1999-2003) :: 2002 - 4x4 Will Not Engage / Lights On Dash Don't Even Light Up
Sep 24, 2016
I have a 2002 7.3 4x4 truck. The 4x4 will not engage, the lights on the dash don't even light up. I took it to the ford dealer and they said the fuse box and gem module. (800.00 to fix). They said the windshield leaked and shorted then out, so I needed to be replaced? I have replaced the windshield and fixed the leak, my question is the fuse box and gem a plug and play and do different years work?

I have a 2002 f250 screw. my door ajar light is lit up on the dash. I have tried the wd40 trick, pulled the sensors and bench tested them. What are the codes the instrument cluster test has for each door?
What I am thinking is, if we get a list posted it would be much easier to diagnose the door sensors for others. there should be a open/closed bit for each door. possibly a code for all doors open too. I am curious if there is a code for bad communication on the VSM.
From what I have read, correctly working the doors should read 00 when they are closed. drivers front open=80, pass front open=40 ... My door code does not change no matter what combination of door open/close I use.
Truck is 2002 f250 crew cab ...
My code is C0 ...

I have a 2002 7.3 e350 quigley 4x4 Sportsmobile with 312k miles. 2nd owner. Bought it with 295k miles 2 years ago. From what I gathered the tranny is original.
After reversing at a downhill angle, stopping, and shifting the lever to Drive, the tranny doesn't seem to put Drive in gear and depending on the angle of the slope, the van will roll back or barely creeps forward even with throttle. Put it in 1st gear, and the tranny engages that in gear and drives forward no issues, then I can shift to 2nd, then Drive and the tranny shifts fine after that.
No weird tranny noises or clunking. Noticed this issue about a month ago or about a couple thousand miles ago. Did tranny service (drain, filter, fill) at the ford dealership at 305k months ago.
I can only replicate this issue when Reversing on a down slope. On a flat surface van Reverses and engages Drive like normal.

I have a buddy with a 1999 F250 W/7.3 TD. His property is accessed through a couple miles of hard terrain, so this may wind up being a loose ground or something that pulled loose.Anyway, the truck just all the sudden won't accelerate. It'll crank & idle all day long, but when you hit the gas.....nothing happens. I realize the diesel doesn't have an accelerator cable, as it is drive by wire. First thought was the APP sensor(accelerator), but most of the dash indicator, O/D, etc. lights are inop too.

When I position the switch into 4x4 High or 4x4 Low the dash lights do not come on. Also, I have a vacuum leak at both hubs.
I tested the vacuum lines from the ESOF solenoid (or whatever it's called, the box on the fender where the vacuum lines originate) and I don't have any leaks in the lines. I put the Mighty Vac straight to the back of the hubs and I definitely have leaks at both hubs.
So, why am I not getting the light on the dash, and why do I have leaks at the hubs? FWIW, I replaced both wheel hub assemblies in March, and everything worked fine at that time. I'm hoping the yellow o-rings are still good. Is there a chance I lost torque on the four bolts behind the hubs causing a failed seal? Is there a seal on the outside of the hubs that could've failed?

My yellow 4X4 indicator light on the dash won't turn off for several days after engaging the 4 wheel drive. I have a manual transfer case not the ESOF system, I am certain the 4X4 is disengaged, but the light stays on, so something is sticking. It will usually take several days for the light to go off. I have had to engage my 4X4 system a bunch the last 10 days and had to engage it where I park at my office yesterday due to a huge mound of snow right on the edge of my parking space, man the guy who plows my lot sucks..oh wait, that's me.. so it will be a while before the light goes out on it's own right now. What needs to be sprayed, lubed, tapped with a hammer, replaced?

I have a 99 F150 5.4 V8 4x4, My problem is when I engage 4Hi the dash light "low range" turns on but NOT the 4x4 light. Now if I go to 4Low the 4x4 light turns on(Low Range light stays on). So in essence the lights are backwards. In 4Hi it is not engaging 4 wheel drive. Also its a SOTF not electronic selector.

Ok so i have an 02 F350 7.3 with 89k on it ... Ive had the truck about 2 years now and ever since i bought it the ABS light has been on. So finally i got to scanning it and codes popped up for the front speed sensors and the rear speed sensor. So i went ahead and just put all new MOOG hub assemblies in the truck which come with the speed sensor already in the them and i also replaced the rear speed sensor, which was difficult!!! Becuase the bolt was seized and i ended up have to drill and tap a new one and even then the sensor seats in the hole in the diff but doesn't seat flush with the housing if you really tighten it down, and it leaked a little fluid at first but i ended up loosening up the bolt a little to make it seat better and then i put silicone around the bottom of the sensor and it stopped leaking... Anyway I've fixed both the code issues and cleared them, BUT, the rear speed sensor code pops back up immediately after clearing it and the ABS light on my dash stays lit .... Idk what to do at this point because I've fixed everything and it still pops the code for the rear sensor, I just want the Light on my dash to go off thats all ! ...

I had my dash apart to install a radio. Didn't really mess with e-brake. Got it all put back together and light on dash is on. Where should I start to fix this? Is the switch with two wires hooked to the e-brake the only way the light can come on? I have worked it manually with no luck.

My truck is a 2007 F-350 DRW. I'm not sure when,because I don't use it much in Texas, but My Four Wheel Indicator lights on the dash quit working. I don't see them in the dash at startup either. I'm not sure if the four wheel drive is coming on at all. There is probably a way to check that without driving off into a mud bog, right? Anyway I have looked for blown fuses etc, no luck yet. (15amp#33 under dash and 30amp#3 under hood). These are according to my manual.

This is my "03 F350 single wheel 7.3 automatic 4x4. For quite some time now I have to manually lock the front hubs. Maybe it would work automatically, maybe not, and now I always have to manually lock the hubs.....but I can live with that. The problem now is that the selector switch on the dash isn't working or something else is preventing the transfer case from going into 4x4. The 4x4 light on the dash also does not come on.
I have checked all the fuses and they are good, I do not have a owners manual so I don't know what to look for in the fusebox. Perhaps it is on a relay? Also, I would like to check the dash switch for power coming and going but how do I get the switch out of the dash? I'm afraid I'll break the bezel around the switch if I pry too much.

A friend with a 2003 came to me Thursday. He has a dash light on that is an image of an engine. Sitting in the drivers seat, it is to his left. I do not recall seeing this image in my 2001. What might his problem be?

I installed a new trailer wiring harness onto the back of my 2002 F250 Super Duty with 7.3 diesel engine. Unfortunately, I was 180 degrees off on my wiring. When I hooked up to the camper I blew Fuse #115 (Trailer Tow Battery Charge) as it connected directly to the camper ground wire. I replaced the 20amp fuse and all other fuses were good. Currently, I have all the truck wires to the harness isolated and have power to all of them except for the parking lights. All the lights on the truck work fine.
My truck has a interior fuse panel on the driver's side as well as two small black boxes under the hood, near the brake booster. The under-hood boxes had only relays in them. Two relays in one black box, three in the other. The box with three relays had trailer left turn and right turn relays. which worked fine. The third in that box, apparently, is for the A/C clutch, controlled by fuse #10. The other black box (with two relays), apparently, are for 4WD Shift on the fly, controlled by fuse #111. So, no relay for the parking lights.
Next, I pulled the fuse panel out a little and checked continuity from the end of the parking light wire (brown with white stripe) at the back of the truck to the back of the fuse box and found that it was a good wire with no breaks or shorts to ground, however no voltage is showing at the parking light wire when I turn on the parking lights. The harness at the back of the fuse box has several wires going into it. The parking light wire (brown with white stripe) is in the same harness as the back-up light wire (black with green stripe) and the back-up light does have voltage, when I put it in reverse.
I'm not sure what happens inside of the fuse box, i.e., how does one fuse run a few wires... is there some kind of circuit board? I know the easy way would be to run a vampire connector from the truck parking lights, or maybe the license plate light to power the trailer lights, however, I'm just not built that way.

I have some LED strips i bought, some i am going to install under the door sills to light my nerf bars/steps. The rest i am installing under the bed rail to light the inside of the bed. I want them to come on with the interior lights. So when i hit the unlock button on my key fob, or open the door said lights will come on.

I have a 2002 f250 CC 4wd 7.3 and I have no power to my reverse light sockets. I am stumped, all my fuses are good, I don't think there's a relay so i haven't checked that. My neutral safety switch is good, I'm getting power to both the blue/pink and black/pink wire. What it could be, at first it was constantly blowing fuse 27 every time I put it in reverse but then it stopped blowing it obviously because they won't come on.

I have a 2001 F250 Crew Cab with Powerstroke. The dash lights are starting to go out one at a time. How do I get to and replace the bulbs?

I was to leave tomorrow for a trip with three horses. Last night when I parked my truck the dome light went on and off and there was a noise (like a relay opening and closing?) coming from the area. (I have been having issues with the turn signal getting "tired". At times they would only come on solid then other times try would quit after sitting at a long light.)
Checked my manual for fuses to this issue and I removed the fuse in the spot indicated for the "dome and courtesy lights", number 14. Actually I had removed spot number 15 (5amp). This ended the noise. Drove the truck after and all seemed in order, cruise control, turn signals, interior lights! This was the incorrect fuse according to the book! This event occurred with the ignition in the OFF position. Not wanting to start my trip before I get this in order.

A few weeks ago i lost the speedometer and the abs light came on. 6 hours later when i got home I tried diagnosing it, but everything worked. Yesterday, the same thing. No speedo or odometer, abs light is on, and the OD off light is flashing. But the trans still works fine, going through all 5 gears and torque converter lockup. plus, pushing tho OD button turn OD off, hit it again and OD engages again. (the truck has a 5 speed allison trans in it) i put the scanner on it and got No response from module for the ABS module, the GEM/central timer, and Hybrid electronic cluster. There are no trouble codes, but it did show P0500 vehicle speed sensor A this afternoon on the way home, the speedometer and odometer came on and worked for .4 miles, then went out again. Where I should start?

This morning my 02 decided to turn the ABS light on, and start bouncing the speedometer. plus, the OD light is flashing when stopped with foot on the brakes, but the trans is shifting fine. Nothing changed on the truck except almost 3 inches of rain fell last night. Will AE tell me if the VSS is going bad?

so got to work today, truck engine light comes on all foward motion stops. Just coasts and idles along. I have 280k on the orig stock trans. I also have dp tuner and did the valve body upgrade along with adding the 6.0 cooler hoping to extend the life of the trans. Reverse works. So i asume I am needinf a new trans. My options are Ford HDr4100 orig 4100, Or BTS built trans. I also pull a toy hauler as well. My question is If I order the BTS can I have a my local shop install it or does it need to be programmed at the dealer. If I get the HD from ford installed will I have to remove the dp tuner chip to get it programmed and also will i need another new valve body replacement.

I have a 02 f250 4x4 7.3l.... I drove it all weekend and no problems. It sat till yesterday I got in it to go to church. It started up and had a little miss was around 60 f. Then the od light started flashing. Not in any code just constant flash. I was parked down in my drive way. It idled fine but acted like it wouldn't take fuel. So looked around and found the hose on the map sensor was broke.
So today I fixed the hose. Checked the oil level and battery connections. Still running weird and flashing od light. I got under the hood and wiggled plugs I unplugged the ice. It revved up then back down and started running smoothly. Got in it and it backed out of the drive way. It ran and drove fine. What I need to know is why??? The ice is a new one from Ford.
