Default Buzzing is killin me

The tweeter on the driver side dash is buzzing loud and crazy, it's matching my rpm's too. I disconnected it, but then the sound moved to the driver door speaker. Nothing has changed recently or have been messed with to cause this. And also the other night was driving back from Ford Fever at MIR in MD, and had my headlights and fog lights on and everything thing started flashing, WTF. turned off the fogs and it seemed ok. Is it my Alternator? Battery? Grounded Wire? Please help, the buzzing sounds alomst like a supercharger with out the added hp/tq, so i dont like it. thanks

have the alt checked for a bad diode that'll allow ac ripple current to back feed, if that is okay, could need a new set of wires that are rated/ radio supression wires, or radio needs to have a noise filter installed.

it could be Alternator induced radio noise.... check the small capacitor that is by your coil.. it looks like an old school condenser for igniton points

Alternator was checked and the guy said it's normal. Something that's causing the speakers to buzz when the radio is on, and the headlights (just the center lights, not corner or parking) to blink when the fog lights and radio are on.

as they said above there is an ac noise condenser mounted on top of the coil that probably needs replaced. Also be sure to chech an make sure the factory grounds for the battery are tight.

pickup a radio noise suppressor at your local parts store.

then buy some suppression spark plug wires.

then do this.

You need to check the wiring in the column at your multi-function switch. It is know to melt at the connector from the fog lamps. This is what causes your headlights to go out.

^^ what he said.

if those wires are melting there will be big problems down the road.

some thicker plug wires will fix the speaker noise.
