My honda Civic 04 whistling noise

you possibly have a tire going bad .

hi
if the noise is there and it get loud as the speed increase
then check your wheel bearing.

Check transmission fluid. Is it full...?
Yes. Bad transmission.

Is it when your wheels are turned left on take off? sounds like drive shaft. check cv boot for split. if you know a mechanic they will know if it is the drive shaft as soon as they drive it. If it is a crook drive shaft theoreticly it can not come apart but very annoying & embarassing.

Ok, whenever i turned on the heat in my 2009 Honda Accord, i hear a whistling noise, then i turned off the heat and it's gone. It only happens when the heat is on, help?

It sounds like your brakes are worn out. The front wear faster than the rear.

The CV axle is bad, If the CVboots on the right side are bad, have it replaced too.

I had a problem with a whistling car after 50 mph and it turned out to be the front window gasket. I put silicone on the trim and problem solved.

if this is happening all the time i would jack up the car and manuelay turn the wheels and listen for anything unusual if it is happening when you press the brakes i would pull the wheels and examine them for a stuck caliper or slider, before removeing the wheels try shaking them side to side and up and down to check for exxcessive play that may indicate a wheel bearing or other loose front end parts, fyi a bad wheel bearing when going around 40-50 mph and veering slowly left then right will usally make noise going one direction worse than going the other -jeff

i would have it inspected to be sure it could be a brake shoe
