You can test your blower motor by disconnecting the leads and using straight battery power (with a 20 amp fuse) and ground to see if the motor works right. If not replace it.
 
If the motor is okay it is probably your blower motor control module that's in the blower housing where the blower leads go. It's under the relay panel. The relay panel has two bolts and can be pushed up some to get room to take out the blower control module. It works like the resistors in old style systems; it sticks into the air stream for cooling.
 

#8 of 9 acadia front ac blower motor stopped - fixed it! by michigal

My '07 Acadia blower for the front ac stopped working. The aux (rear) blower worked fine, so I knew it wasn't the ac (thank goodness!) Thinking it was a bad motor, we found out where it was located (under the front dash/glove compartment) - we pulled down the cover, and easily got to the blower, pulled it out and put some wd40 on it - surprise! it started working! back in it went, and all was well. .

2008 GMC Acadia front blower went out. Rear ok, compressor ok. Just like you, took out the blower motor and it was tight, tight, tight. A little WD-40 and it was good as new. Blower motor is under glove compartment - black panel with large bump in middle. Two pins hold in place - pull pins out with pliers to unlock and remove. Blower motor is black cylinder where the bump was. Grab it and twist to unlock and remove (no screws) - a lot like an old headlight bulb. Once you have the blower assembly removed, there are two torx screws that hold plastic cover in place. Some lube at the bottom and under fan should loosen it up. Looks like it's getting water/condensation and rusting a bit. Hope it lasts a little while before locking up again!
