Review on 2004 2007 Chevrolet Trailblazer 2003 2009 Oldsmobile by Cole Dutta

The hardest part was isolating the failed actuator. Three are used on the car. The easiest way to do this is to disconnect and then reconnect the battery. When the ignition is switched on, all actuators must move during the reset process. Look for the one that doesn't move and you'll need to replace it. The most helpful tip I can give is to use a small 1/4" SAE socket with a hand screwdriver. a regular 1/4" ratchet and the screws are loose so the hand drive has worked really well for me . The new drive fit snugly and worked as it should.
