Having problems with your 2006 Chevrolet Trailblazer ?
Loud whining noise
\015 My trailblazer is making the same noise. it is driving me nuts. I changed the Idler Pulley and the altenator. I used the screwdriver test on the altenator and it sounded like it was making the noise, so I put a new one in, that wasnt the problem! Any suggestions?\015
