Hi Scotty,
I have a 02 Chevy Trailblazer with 179,000 miles on it. My TB is making a humming noise when I drive normal Speed or fast speed . What is the problem and can I fix it my self.
thanks and go Scotty team
your throttle body is humming?
Or did you put TB as the initials for trailblazer?
Yes
What does that mean
Do you have your radio on? I have that same vehicle with the bose system and amp and sometimes I will get alternator whine through the speakers. I have tried everything to try to fix it and have not ever been successful. In my car if i turn off the rear speakers it goes away. Does it get worse as you accelerate?
How old are your tyres?
If they’re all brand new, are you still on the original wheel bearings?
Otherwise, pinpoint the general area of the noise first -
I thinks it’s the wheel bearing
Did you diagnose it or are you guessing?
Well lots of things can make humming noises watch my video finding the source of car noise is Scotty and you can find out how to find any type of noise in a car
Ok thanks
