hi I have a new to me 02 f250 4x4 v10 6speed man while driveing home to day a buzzer started going off under the dash when i touch the brake peddle it stops no dash lites on the cruse hasent worked since i owned it three weeks could these be realted what is buzzer warning all help appetacated

 

I had a similar issue recently on my 02. It was the fuel relay buzzing and clicking when the car was off due to low voltage from the battery. My battery ended-up dying. Maybe your alternator? or maybe the brake switch is failing.

 

At first i thought brake switch but then i noteced if turn signal turned on it stoped. After some qualty time under the dash i found source of noise i think it is a multifunction relay/flasher when unpluged turns dont work wiredest thing is all six brake/turn lights work but turns flash fast i hate to reaplace parts with out knowing fault thankfull for all help

 

ok so the noise was coming from what turns out to be turn flasher the buzz has stoped but turn siganals flash fast but the four ways flash at normal speed all bulbs are good any thoughts
