OPEN THE GLOVE BOX DOOR ALL THE WAY DOWN TILL IT IS POINTING AT THE FLOOR NOW REMOVE THE VACUME POD THIS IS THE ONE THAT CHANGES THE AIR FLOW DEFROST /HEAT / VENT /AT THE LEFT SIDE OF THE DOOR THIS IS DONE BY PUSHING UP AND THEN SWING IT TWARDS YOU NOW LOOK ON THE TOP OF THE HEATER BOX UP HIGH NEAR THE FIREWALL YOU CAN SEE THE BLEND DOOR MOTOR IT HAS 2 - 5.5 MM SCREWS HOLDING IT ON THE HEATER BOX OH BOY THIS IS THE HARD PART ALL YOU NEED TO DO IS REMOVE 2 SCREWS I JUST DID IT 2 HRS AGO I USED A 1/4 IN DRIVE RACHAT AND A 5.5 MM SHORT SOCKET A THUMBWHEEL OR THUMBWHEEL RACHAT MAY ALSO WORK BUT IT CAN BE DONE WITH A 1/4 RACHIT HAVE FUN TAKE YOUR TIME DONT GET MAD IT WILL COME OUT.

Best place to get the replacement actuator (Doorman 604-106) is Amazon. $94 compared to local parts stores at $135 and up. Make sure you have a kid or wife handy as you'll need small hands and fingers to get up on the screws holding it down. You also need to disconnect the power connector going to it (not mentioned above). Lastly, the old actuator might be "stuck" and doesn't just pull up and off. Wedging a screwdrive between it and the housing it rests on will pop it up. OH...make sure if you have a Bravada that you get the above part # as its for the Automatic Climate Control system in the Bravada.

And there is a great write up with images too at this link:
