TB issues

[jauto98]

Hi all, I recently purchase an 04 TrailBlazer and so far have enjoyed it. However, I am having some issues if anyone could help me out.

 

1. Sometimes I hear a high pitch noise kind of like wind noise coming on the passenger side of the vehicle. I have noticed this during slow speeds such as when I am turning or slowing down. It is sort of hard to tell if this occurs during higher speeds because of wind and road noise.

 

2. Lately, I am having this purging noise this morning. It occurs when I shut of the engine. This is when the AC has not been running.

 

3. Intermittently, during moderate to heavy acceleration, I get this sound thats like disc rotating and rattling. This usually occurs above 2500rpm and during the afternoon.

 

Hope someone has a suggestion before I go to the dealer to see what is wrong. Thanks,

 

Jeff
