Ford Wiring/Electrical :: 1978 F150 - Dash Lights Are Not Working
Jan 13, 2017
Dash lights are not working in my 78 F150. The climate control lights come on and are dimable with the headlight switch. I pulled the cluster and the Blue/Red wire has voltage. Which might be the ground? The Seat belt light comes on at start and the left turn signal will blink. What am I missing. Oh the cluster is deteriorating. some of the bulb holes are chipping out.

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 2000 Ford F250 lariat 7.3 .... This vehicle has an aftermarket double din stereo pillar gauges for Pyro meter and transmission temp and has also had a snowplow attached but since re moved since I purchased it. It also has H ID headlights, which are run by the passenger side headlight connection.
The problem I'm having is that whenever I turn on the parking lights it is blowing the number eight fuse under the hood. Which is giving me no dash lights running lights parking lights or taillights. Initially the fuse would last for a few minutes and then burn out. I should also add that the trailer wiring harness doesn't work either and the driver side headlight will work sporadically.

2003 f150 supercrew with 166,000 on it. Daily driver. Keeps randomly blowing 10A fuse under dash that controls ABS4X4 urn signals. No routine causes. Just blows at random times. Fuses were blowing instantly upon replacing then stopped. Doesn't blow when turning switches for turn signals or when turning it to 4x4. Just does it randomly. Sometimes will go months without blowing. Tore dash apart and can't find any wiring issues there. Could be somewhere else? Is ABS4X4. Turn signals going bad?

I got my first truck today and it's a 1988 Ford F-150 and it runs great! The only issue is that the speedometer doesn't work and I won't be able to register it until it does. I was wondering what I can try out to maybe fix the issue and if not, how I would replace it. Every other gauge works, it's just the speedometer that isn't. The needle doesn't move at all it just sits at a 0 all the time.

I have been trying everything to get my speedo working on my Ford. It didn't work for 3 months after I got it then I decided to put some gear oil on the cable. This made it work for about 200 miles then it would only work with the clutch in and then not at all. I've replaced the speed sensor(not one on rear end the thing the cable goes into), and the gear that goes on the end of it. If I hook a drill up to the cable the tach moves. Could the cable be stretched or just needs some speedo cable lube?

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...

Just bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.

I bought a 1952 F1 that is mounted on a 1978 E350 chassis.( 351W )
It has all the 78 wiring installed. When cranking engine, it will not start, unless you release key to run position. You have to get engine turning over, and then quickly release key to start. Checked back of switch, not losing voltage at ignition post while cranking...

I have a 1991 idi diesel f250. My dash lights have entirely gone out and i cannot seem to figure out why, i checked the fueses under the driver dash and under the hood for that matter and nothing is blown.
At the same time, the dome lights, door lights, cab lights, stereo, windows, ever the light in the ash trey etc, work perfectly fine. Could a wire have come loose behind the dash cluster and shorted out everything in the driver area?
I still get the high beam signal, check engine, engine, wait to start, and water in fuel light in the cluster. but no back lighting (when turning the key to the on position)...

Turn signals quit working on my 2006 E-150. Swapped out the relay under the dash and it did nothing. Also noticed the brake lights aren't working. The headlights and taillight a are working. I pulled the fuses under dash for the lights and they tested ok. I did notice the flasher relay was making clicking sounds intermittently even when not touching anything.

Truck is in signature. All of a sudden my oem fogs don't work. I took a volt meter to the connection where the bulb plugs in and no juice. Checked the fuse and its good.I get 12 volts or so at fuse for fogs.. The fog light illuminator lights at the switch when I pull the switch. Is there a relay somewhere under the hood. All the relays in the fuse box checked out good and none of them in my truck guide were labeled for the fogs anyways. Looked for 3 hours and cant find a thing. If all else fails how do I cut the wires at the fog lights and run wire to cab with toggle switch? I know I need a relay right? I am not familiar with hooking up relays..

OK, I just got done replacing the alternator on the wife's 05 escape 3.0 V6, after it started on fire. The 3 wire plug was melted onto the alternator, so I had to replace the pigtail. I'm 99.9% sure that I got the wires in the right place. But now, after putting it all back together, it idles sporadically, when I drive it seems almost like it's trying to start out in 2nd gear, and shifts oddly. And there are no dash lights or gauges. Headlights work fine. And everything worked normally before I took it apart.

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.

My brake lights don't work. Turn signals, tail lights, hazard flashers work, but if I hit the brake, nothing happens. What could possibly be the problem? Could there be a wiring issue?

I did lower the steering column, onto the seat. Also lowed the dash and the wiring. Does it sound like the Multifunction switch could be bad? I can put it in drive, so I don't think it's the brake light pedal switch, that's bad.

I had the windshield wiper control replaced on my 91 F150 today and found out that the genius who did the repair (and, I might add, broke the wiper control in the first place) forgot to reconnect the dash lights. This was this particular garage's last chance. Everything else works -- idiot lights, hi-beam indicator, running lights, taillamps, hi-beams -- everything BUT the dash lights, so I know it's not the fuse.

I have a 1981 F100, lately when I've been driving at night I notice my headlights, dash lights, and charging light will flicker at the same time, and even sometimes my headlights will flash on and off by themselves.

I have a 1997 F250 that I am fixing up. The issue is this... The dash lights now flicker off when I place the transmission in Drive position. I can slightly move the slack in the gear selector and the lights come back on. When the transmission is in Park, the dash lights work correctly. Not sure why there is some type of switch to control the dash lights buried within the steering column?
