I have the same situation with mine.The only thing I can narrow it down to is that the fuel pump is making that noise.Mine has been doing it fir four years now and it seems to be an inconvience instead of a problem
It could be low on fluid, the syncros could be worn out. does it need fluid?
There could be different reasons the security light is coming on in your Chevy Trailblazer. The fuse could have blown or there could be a wiring short.
the dashboard cluster could have broken. That happened to my 2004 trailblazer and I had to get it replaced
Whining noise near belts had pulleys adjusted any idea what is causing this
If you brake lights are not working on your trailblazer it could be due to a number of reasons. Your fuse could be blown, or your light may no longer work.
What kind of whining? Could be your serpentine, could be your steering pump.
The transmission in the Trailblazer could be low on fluid. The internal shifting mechanism could be giving problems as well, keeping the transmission from shifting into gear.
Could be the resonator
The whining could be related to the alternator. Does the car have any electrical problems such as the battery drains and dies while car running, are your belt(s) tight? in good condition? It might be a belt tensioner or idler pulley that is causing the whining.
Yes, the ignition on a trailblazer can cause head lights to work improperly.
It is possible to drive a Chevy Trailblazer with no power steering. However, it isn't recommended. The steering column could freeze and there could be no way to steer the car.
Could be the solenoid under the truck ...... come and read about the fixes at www.trailvoy.com Trailblazer enthusiasts forum!
