Ford 7.3L Power Stroke (1999-2003) :: 2001 - Buzzing Noise Coming From Flasher Relay?
Aug 10, 2015
2001 F-350, 7.3L,
Has done this off & on for a few years and am tired of it! Noise is kind of a buzzing that seems to come from the flasher/turn signal relay. It stops buzzing when you turn on a turn signal, activate the flashers, or lift up on the shifter arm(?). Had to drive home yesterday with the flashers on! So I see from researching that it may actually be the multi-funtion switch on the steering column. So I removed that, cleaned up all the contacts, and put it back on and the buzzing did not go away.

Had a weird issue come up this weekend. I went to drive my truck for the first time in a couple of weeks and when I got in I noticed a constant clicking from under the dash (whether the truck was on, off or if the indicators / hazard lights were on or off). I investigated and found it was my flasher relay. I have replaced this relay recently (within the past year) to an EP27L to accommodate the LED lighting I installed throughout the truck (hyper flash on the old relay doesn't even describe it properly, it was a constant buzz!) and it has been working perfectly until this point.
I thought it may just be something going on with the relay so I pulled it and replaced with the old EP27 unit I still had. It does the same thing, albeit at a slower rate (every 4-5 seconds). The lights do not blink when it is doing this, but still operate normally when I move my stalk up or down or when I press the hazard / flasher button on top of the steering column.
I am wondering if there is a short somewhere in my multifunction switch that is causing this issue? If so, why would it come up when truck has been sat? I didn't have the time, not the inclination to roll around inside my truck (hotter than hades here in Florida right now) to troubleshoot any further. I pulled the relay altogether until I get some time and cooler weather to look into it further. Otherwise the truck seems to operate as normal, even all the lighting seems to have no ill effects from this?

I went on deployment and handed the wife to crank the truck up she did but didn't drive it so batteries didn't charge back up. I got them charged up and the truck cranked right up. I was plugging it in at night and it would start just fine the next morning. Then a week later batteries kept dying in a few hours during the day. Had to jump it again. then even when plugged in trying to crank it there was a buzzing noise and it would crank but not start. I bought new batteries and it cranked right up and drove fine until I shut it off and same problem and batteries were low again and it will crank but wont turn over. I am thinking maybe alternator.

So I'm working on a customers car, its a 2001 Passat, there is a buzzing sound that started when she would use her left turn signal, and now the sound wont stop, the only way to make it stop is to turn the car off, turn the blinker on, or the flashers. I'm thinking the Turn signal switch inside the steering area.

Now down to the question in hand. I have a 2001 f350 4x4 with7.3 diesel...I have recently noticed a low grind like noise coming from the right front. I have troubled shot the issue and I am 100% sure it is the wheel hub assembly. Did I mention I am running 37x13.50 tires..and now it is the hubs...and they are the original hubs.. My question is every thing I look for shows ABS is on my truck... I look at the hub and don't see it.. so with the Dana 60 front does it have ABS or not? Also, should I go motorcraft, Timken or moog wheel hubs?

My friend and I were working on my truck and he was testing my AIH relay, as he was testing it the fuel pump was clicking on and off a few times over about 10 minutes. He explained that the current must be back feeding through the system and activating the pump. After testing the relay he determined that it non-functional / broken.
When we went to start it there was a strange buzzing from the fuse box area. After testing all of the fuses and then his code scanner not being able to connect to the truck we can only figure that the PCM is done.
The truck will turn over but not start. Any time the key is in the run position the buzzing noise is there unless you pull the PCM relay or the IDM relay. He says (I know very little about this stuff) that the IDM relay is trying to close but because the PCM is fried the IDM is not getting the signal to do so....?
So what now? Do I need a new PCM? He said something about it need to be reflashed to match the old one, is that right? Are all PCMs equal? What else should I know?

I am having trouble with my 2001 F-150. Starting yesterday it would not start. At 1st i thought it wa the battery, so i took it off, charged it, put it back in the truck and still no start. There is a clicking noise coming from a relay in the cabin fuse box, disconnected the battery, removed relay to inspect and everything looks good. After plugging it back in, and connecting the battery, the truck still wont start and there is a clicking sound coming from the dash near the radio. Rhis is my work vehicle!!!

I want to convert my stock turn signals into LED, but i want to do without the hyperblink. I've done some research into this, and have ended up confusing myself. I don't know if I have to add resistors in order to stop the hyperblink that would occur, or if I can simply change the flasher relay and it be more straightforward.

I would I have a 01 7.3 e350 with 111k miles. I drove the van a couple of days ago.it sat for 2 days and now it wont go past 30mph.the van shakes crazy and went when i hit the petal no power with smoke coming out the tail pipe sometimes. When I shut the van off and restart it to drive it,it sounds better. I changed the fuel filter with motorcraft and changed the oil. Here is the kicker. It ran good after I changed the fuel filter the whole day and now its 4th of july and I went to get some drinks and it happened again.

Recently I came across a guy parting out his F-250 with a 7.3 powerstroke. Said it had a blown engine, and didn't know what was wrong, but oil was coming out of the exhaust.
My question here is why that's happening. I don't have any experience with the powerstrokes, so I'd like to know what the culprit is before I even consider buying it.

My 97 F150 4X4 's turn signal flasher buzzes all the time except when brake is depressed or turn signals or hazard signals are active. The flasher is a 5 prong one. What to check?

While doing a visual inspection I noticed that the AIH hot wire (captured nut wire) had broken off and was laying loose. I removed the wire from the relay and made a new 8 gauge wire, I connected it to the relay and was about to add it to the AIH when I got a healthy spark ( it touched the ground wire ) and yes the truck was not running and the key was out at the time.
This sounds to me like the relay has gone south, am I right??? I have a new OEM relay to install but I have a question. In what order are the wires and ceramic fitting go on the AIH post???

I have a 2001 7.3 and have found the engine oil dipstick coming out of the dipstick tube by 6 - 8 inches on three different occasions. Did not think much of it until my other 2000 7.3 did the same thing.
What causes this as afraid it will come all the way out and get into the serpentine belt.

I have a 03 6L Ford F350 and for the most part trouble free. Any way lately I have been getting a clicking noise that sounds like a relay clicking under my dash when my truck is running even when its just idling...
I don't always get it but it has become more common that last few weeks. So I stuck my head under the dash and it sounds like it coming from that little black box's that is attached at the base of the gas pedal ? Could be coming from fuse box cause that what i was going to go after but doesn't sound like it, SO what is the little back box for on base of gas pedal?

The relay for the fuel pump keeps going bad. Is this a sign my fuel pump is going ? I just replaced my 2nd relay ( lasted about 1 week ) 1st lasted 16 years. Or is there another issue to look at ?

Fixing issues with my truck. I just ordered some latex surgical tubing and am getting ready to fix the rattling noise in my rear door by using the Epic's Door Seal Mod. Hopefully this will take care of that issue.
One more annoying noise though. Has there been any fixes to the buzzing window noise that is coming from the front passenger side. If the wind is blowing right and I'm running over 50mph, at times get a loud buzzing noise and really bugs me. Something is vibrating and at first i thought i had a speaker going out but found out that wasn't it.
I've called my dealer and informed them of this and asked if they've heard of this but of course they haven't and this usually means the won't do anything besides look for recalls or something. I have the noise recorded and scheduled an appointment with my Ford Dealer but again, they won't do anything most likely.

I have a 2001 F-350 w/7.3. There was excessive smoke coming from the exhaust. So the first thing I did was to pull the glow plugs to see what they looked like. and while having them out I cranked the engine over. Upon doing so I noticed 1 cylinder putting fuel out of the hole. Meaning it was like you could put your hand about 6 inches above the hole and your hand would be wet from fuel. None of the other cylinders was like that. So what I did was pull the injector from the cylinder next to it and put it in to see if it was the injector failing. But it was still doing the same thing. What would cause this??

I purchased one of the No Start relay for my 2000 Ford F-250 Turbo diesel and need assistance finding the relay to replace.
Originally I thought it was for the fuel pump then then discovered it replaces the ignition relay.
According to the company it's located on the passenger side under the hood. Can't find any fuses there.
I looked in the user manual and found nothing about an ignition relay. Just "PCM Relay Coil, Ignition Coil (Gasoline only), Fuel Heater (Diesel only), Wastegate Solenoid (Diesel only), Injector Driver Module Relay Coil"
The relay I purchased is from: "No Start" Relay, "No-Start" Intelligent Relay System, Vehicle Theft Deterrent

2004 F250 SuperDuty 6.0L Diesel. The turn signal (left or right), it would make a buzzing noise, so I located the relay under the steering wheel (by putting my hand on it and seeing which one was buzzing) and replaced it, I bought a replacement at Schucks, then the buzzing noise went away, and the clicking noise is back.
But.... I don't see the turn signal lights in the dashboard and the turn lights are not working, I checked, what could be the problem ? I read the owners manual, in the fuse box under the steering wheel, fuze #18 is used for turn lights, but it is not blown.

I've recently picked up a new noise. At idle the engine buzzes. It sounds like the vacuum pump running but coming from the engine (the vacuum pump is not running while this noise is happening). This noise could also be happening while I'm driving too but the RPMs bring up the engine noise so I can't tell. Nothing looks out of the ordinary and I haven't done anything different that would give me any direction (no off-roading). It was just there one day.
The truck doesn't seem to be running any differently (right now), just the buzzing. I just want to catch it if it's going to become something serious. An ounce of prevention is worth a pound of cure (not to mention the towing bill!).
