location of heater motor and ease of replacement

Asked by chevy Jan 19, 2007 at 01:08 PM about the 2003 Chevrolet Trailblazer

Question type: Maintenance & Repair

When blower motor is turned above level 1, the dash shakes and makes loud noise from where I believe the motor is.  The heat is warm but no extra force when the level is turned up.
