I'd recommend you buy a Haynes or Chilton aftermarket service manual, they are <$20 US and will be available at nearly any chain auto parts store.
Either will give you enough information to find and possibly remove the blower assembly.

The blower motor control module needs to be replaced, that will solve the problem. The module is underneath the hood on the firewall in the back. It has 2- 6mm screws. Unplug it, pull it out, put the other one back in. Plug it in. This is common for this model buick.

Hi. The removal is really easy; unplug the motor under the glovebox, and remove the 3 screws that holds the assembly in. You can have it out in 10 minutes.

SOURCE: replace the blower motor.
Under the glove box:
Disconnect the blower motor power transistor electric connector (the transistor is far over to the left, with a curly wire coming down to it.)
Remove the blower motor power transistor mounting screws the remove the transistor.
Disconnect the electrical connector from the blower motor (slightly to the right of the motor).
Remove the blower motor mounting screws and then remove the blower motor assembly.
(there are, I believe, 3 screws; 1 just below the connector; 1 above the connector, higher up, and slightly to the left; and 1 over to the left of the blower motor)
Remove the circlip from the blower motor shaft to release the fan from the motor.
Installation is reverse.
Hope this helps you deal with it.
