Hello
I am new on here I have a question to all that have trailblazers, I have a 2008 trailblazer that Vibrates in drive and when I am at a stop light but when I went home I took off my serpentine belt off and notice I don’t have any vibrations when the belt is off can it be the motor mounts or the fan clutch

The typical reason for vibration at idle only is bad motor mounts. But removing the belt should not affect that situation. In your case I would suspect anything that is driven by the belt.
