can i add cruise control to a Chevy Trailblazer not equipped from the factory?

Yes you can, the cheapest way to go is by going to your local junk yard and taking the system off of one that is equipped with it. Your fuse block is already set up to receive it; follow either the Chilton or Haynes manual when disassembling the junker and when installing it in your vehicle.
