what engine?

 

4.2 straight 6 engine.

 

purge solenoid is located on the driver side of the engine block...below the manifold. disconnect the electrical connector and evap tubing and replace the part. you may have better access from underneath or thru the wheel well liner.

this is the welcome area. for future threads...post in the trailblazer section and you will get more responses.
