When my truck is parked, it drains the battery. Have taken to ford and had checked and tested. They said it was the PCM. I have had the PCM replaced and programmed. Still having the same issue. Have just put in the second new battery. Truck still has a faint humming noise coming from the engine compartment and draining the battery. If I pull the #53 relay and put right back in it shuts off whatever is not shutting down. I put a maintainer on it over night.

The speakers with my sync stereo system sound terrible. They sound fuzzy and vibrating like they are blown but I know they're not because it does it at different times for different speakers throughout the truck. It also doesn't matter if it's radio CD Bluetooth it all sounds like crap.

The engine of my F150 5.4 Lariat sounds as if it was diesel, and on the passenger side the engine block makes a clanking sound. When I start it it doesn't make the noise, but as soon as it warms up it starts again. I checked the cranshaft's connecting rods and everything looks fine, the timing belt is new but the noise is still there, and it vibrates and loses accelaration when you throttle it.

Hello, I have a problem with my 5.4 v3 truck, first I thought it was the chain but after disassembling and changing the tensors I saw some damages, and then changed the oil pump. It kept doing the same noises, in fact you can hear it even more, and also it burns the raw gas. The engine is not vibrating anymore, but I don't get any warning or a check engine light

When I start the truck for the first time it makes a metallic sound that lasts for a couple of seconds

Radio works,but cannot see station or time, sometimes radio changes station by itself. CD player will not accept cd, when it does accept cd it reads Error. Also overhead console does not work any more, no time,temperature or direction can be seen. I've already checked fuses.

Our F150 Eco Boost has started making a wierd noise when we start up the engine...it starts and runs BUT is making a shreeel noise. What would this indicate?

I have a squelling-chirping kind of noise coming from the lower to mid way passenger side of the motor only while in gear.It gets louder if i apply gas but will stop once i put it in park and neutral.It's not the belt because it still makes the sound with belt off, help me please!!!

Good afernoon, I own a Ford 150 fx4 2007 and recently I've changed both VCT (Variable Camshaft Timing), pinions and roller chains, a camshaft, spark plugs and coils. I have as well changed the oil but the engine is now giving off a sound at low revs, as if those chains were touching themselves.Even more, if I drive in reverse, the car usually starts trembling and, in order to stop it, I need to desaccelerate or stop it. No failure is provided by the computer, any ideas?

Ac blower not working. AC not running. Hear clicking in blend door area. Fuses and relay test good. Please help. Wife not happy... I live in Austin

After taking my 2010 Ford F-150 XL to a local mechanic who replaced my heater blower unit after it was successfully replaced and now up and running my radio in which all lights and displays come on however no sound is coming from the speakers which leave me to believe somewhere a connection failure has occurred somewhere underneath my dash between the radio itself and my blower unit any ideas?

Please give me the fuse number for the exhaust valve motor not able to change exhaust sound Thank you very much Tom Gormley 215 824 1947 tomgormley86@gmai.com

Once the ignition key is released after starting the vehicle, the is a grinding noise that lasts at times a brief second or two and at other times it last several seconds. Sometimes is does not do it at all. It seems that it does it more frequently when cranking after the vehicle has ran for awhile or driven or when its hot outside.

The battery saver relay is making a clicking noise and now the truck doesn't want to st

When the door is opened a clicking starts. It will continue for a short time after starting the truck.

I replaced it, but still makes noise, I think it needs calibration done, but can not find the fuse for it, can you help, please. ?

Radio works but no sound in my 2010 f150 the a. C. Quit working at the same time

When warmed up accelerating even slightly turning corners sounds and vibration comeing from rear end?? But not until warmed up

When I accelerate a little hard there is a thumping noise, but there is none if I do it slowly. I already changed the bracket where the wheels are attached, the differential was checked and everything seems alright. Somebody told me it might be the gearbox mounting, could it be?

I did not see the knock sensor wiring

Just about everytime you turn the truck off this loud noise like pressure trying to escape, its not the IWC (tested an passed) and I did replace the oil pressure switch but light remains on, does seem like the oil has a faint fuel smell. It doesn't have a Ford oil filter (ive read that could cause issues with this motor) but I did get a oil change because process of elimination with some of the diag ive done. I haven't checked the pcv value or test the fuel thing on the driver value cover yet or ac and alt. But does seem like the noise is up top

I keep having an issue with misfires on cylinders 1 & 4, after I replace plug and coil issue resolves for a while. I also am hearing a noise that sounds like a resetting socket wrench when accelerating. I have replaced the motor which had a similar sound prior to replacement.

I hear 5-6 seconds of clicking noise from the engine after i start the car. It's on and off but i mostly hear it after the truck is pack for a while

And then the brake light came on and the then wanted me to shut off truck dk I did and then there was nothing no cab lights or head lights and power anywhere in the truck

Audio system doesnt work. Just a popping sound every 6 seconds. Continues even key in or out

Just rebuild the alternator like last month and fixed an electrical problem it had that had cause the alternator to blow now 2 days ago the alternator is blown out again

Wheel bearing noise, how replace wheel bearing
