Ford Wiring/Electrical :: Buzzing / Headlights And Side Lights Flicker
May 5, 2013
Series 7 , 82 model, light switch drama. I think they worked fine before I had removed the dash but it has a multi plug that I never interfered with but the truck had been in water and the contacts on it were rusty and I know the unit has been submerged.
Anyway, the unit clicks and sort of buzzes and the headlights and side lights flicker and the rear LED lights barely flicker, need to watch closely. I have cleaned and used contact fluid all connections under the truck as I washed it the other day too.
Brake lights work perfectly, indicators too, just associated lights from this pull switch. The unit gets hot, not burning hot but hot enough not to hold for too long. So, thoughts ?
Need new unit ?
Touched something ?
Water ingress finally making unit fail ?

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.

While driving I turned on my headlights and my car became possessed. My warning lights started to flicker on and off, my car was dinging out of control. The speedometer, gas, and RPM gauge went to zero. My brights light would not come on. My dinging for the lights being left on, or the key being left in the ignition, after the car is parked, and the door is open, will not go on either. I turned my lights off and all was well. Turned them on again and the same thing happened.
Now, the following day, it is doing this periodically every couple of minutes while I'm driving, whether the lights are on or not. My radio and head lights work fine. I checked all my fuses and they all seem to be AOK. I disconnected my car battery and reconnected it to see if it would reset and it still did the same thing. One other strange occurrence. The last month or so while I've been driving my battery light came on for a few minutes. I had the battery checked and it is not bad. Then last week my gas-cap warning started to randomly appear. I changed my gas cap, and guess what.....it still came on, at random.

This AM noticed the D2 driving lights appeared to be "on" the brightness was about 10% of the norm. Went into cab and flipped the switch on and the lights lit up normally. Turned off. Looked again and lights were "on" in a dimmed way with a noticeable "flicker" Disconnected wire from power source. These are 2 months installed. Is this an internal fuse in the wiring harness or the cube shaped relay? other?

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?

I have a 2000 F350 7.3. I started out with my batteries dying after a few days of sitting. I found the interior lights were coming on dimly, and the relay buzzing. great, got it. I pulled the fuse and ordered the dimmer/light switch. I came back next week and the batteries are dead again. Charged them, drove the truck, and then the radio starts coming on without the key on. Pulled the radio.
Next day the truck starts fine, but now the seatbelt noid is going off all the time and the tranny overdrive is blinking "off" but still shifts fine, and goes into overdrive. The speedometer also works erratically... I read a post about the marker lights leaking, I looked and that's a definite possibility. My question is are all these related back to the GEM or BCM? or more problems?

So I recently bought a 1997 7.3l F250. It is in fairly good condition, but it has some problems with the lights working. The turn signals and hazards all work, as do the tail lights and headlights. However, when I hit the high beam switch, the headlights cut off entirely. Also, the brake lights do not work at all. Ive checked the bulbs and since they all work Im not sure what the issue is.

Wondering if there is a way to program the headlights and running lights so they DO NOT come on when I open the doors?? And to turn OFF when the switch is off??

The front running lights come on immediately, but the tail and side running lights take their time coming on (usually 10 to 20 seconds later. 95 Ford E-350. Is their a relay that could cause this issue?

2005 Super Duty 350. Getting ready to get my truck DOT-ed and I noticed the front amber side marker and parking lamps are not working (both in the headlight assembly). There is a fuse called "exterior lamps" that I believe these are on, the fuse is fine and all the rest of the exterior lamps on the truck work fine (all other markers, clearance lights and I.D. lamps on that same all inclusive circuit). Is there a special relay or something else I'm missing for these four front bulbs?

What I am trying to do it put in 2 led spot light for added backing up light. What i want to do is have them turn on when put into reverse but also have a switch i can use to turn them on when not in reverse. Just need to know what relay I need and if it even can be done.
I was also thinking of just taping into the wiring harness and adding a wire that goes to the spot lights and another wire that goes to a switch that I could turn on and supply power to the light when not in reverse (I know it will light the revers light also) but is it ok to do that?

Two Issues....
1.My rear dome lights work when manually turned on. They do not come on when the door is opened. However, the front dome lights do.
2.The lights on my side mirrors turn blink when using the turn signal, and when hitting the lock/unlock/remote start buttons. They do not work when driving around with my head lights on.

I have a 97 F250 HD. Wiring the rear tail lights. When we bought it the had cut off the wires going to both sides of the rear lighting assemblys and I was wondering what wire went to what i have the left turn signal working just can't seem to get the brake/back up light to work on that side and i can't figure out how to get the right side going either.

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.

Tried to start my truck after sitting for 2 days in sub zero weather. wouldn't crank. pulled the batteries and charged them over night. Tried to start it the next day-wouldn't crank but the starter relay clicked. Was going to pull the starter and check it but decided to replace the relay first. replaced it and tried to start but now have no power to the cab-nothing comes on. I've checked the batteries with a load tester and they are ok. I've checked the fuses and they seem to be ok. when I tried to start it and the relay clicked there was a loud buzzing noise that seemed to be coming from under the dash. it has done this before but this time was louder than usual. I live out in the sticks so taking it somewhere is a last resort. It is a 1999 7.3 with 290000 miles.

I've been wondering about this issue for about a year now. I haven't torn out the stereo to see if the wiring is jacked up (came with the truck). When I have the truck running and the radio is on I pull the light switch and the radio turns off, then turns back on...... The radio also buzzes when the truck is running, kind of like it has a bad ground but I've checked the grounds and powers and all is good.

Here's the breakdown. I have a '95 Ford F150 that I bought the previous year and it has been nothing but a problem. The most recent problem is the attempt to turn on the headlights. I will pull the plunger to turn on the headlights but I will only get the parking lights and when attempting to turn on the high beams I still get nothing. The only way that I get any sort of lighting is if I pull on the turning stick (almost like doing a manual override on a tripped wall plugin). Now here's the kicker. I still have parking lights, brake, tail, cab, and dash lights. Winter in quickly approaching and the nights are already getting dark, pretty soon the days will be just as dark.

Ok, I admit this isn't on a Ford, it's my old man's 1970 AMX, but it's an odd electrical problem we can't figure out. The front right blinker works fine when the headlights are OFF but when the headlights are on it doesn't blink. The other three work as they should. He has tried new bulbs, ohmed and voltage tested the sockets. Ohm reading was around 1-2ohms and voltage was 9v.
The voltage also fluctuated when the blinker was on but when you put a bulb in it didn't blink. He has noted the bulb on the passenger side is brighter than the other side. He's trying to get it ready to take to Pigeon Forge next weekend for a car show and I 4.5 hours away. What could be going on??? Could a bad headlight switch cause this? Bad socket?

On my 2002 Ford Escape my high lights do not illuminate. I changed the light but it does not light up.
On the dashboard, the little blue light does not turn either to indicate that the switch is high.
Is this a relay, where it is placed? Otherwise what would be the problem?
