Speaking of Blower motors.   
      
   Last spring I replaced the cabin filters that most pickup trucks and most   
   Tahoes and Suburbans come with.   
      
   The Silverado requires two such filters installed back to back, which are   
   easy to R&R, once you learn how.  The first time I did this, there were   
   two filters in the box, but I couldn't find more than one in the slot   
   where they go under the dash. This time I was bound and determined to   
   change both, as I was hearing some noises in the high-speed ranges of the   
   blower motor.   
      
   I finally found it, but it wasn't in plain sight, which is why I missed it   
   last year. Long story short, I changed them both, but that didn't ease   
   the blower motor noise. So, I went back to my Silverado manual and found   
   that I could R&R the blower motor with the removal of one screw and a   
   twist of the motor housing.   
      
   As it turned out, the blower motor was full of leaves that the first   
   filter had stopped, but they were also the cause of the motor noise and   
   what seemed to be an 'imbalance' of the squirel-cage fan. I can now use   
   the blower at full speed and it is like new again.
