It started out being my power windows. They would occasionally act like they were losing power. They would work, then they wouldn't. I learned to just be patient. I noticed that if I kept playing with them, the power would come back and I could move the mirrors. At the time I didn't know if it was an electrical problem or if the motion pad itself was going out. I then started having trouble with my power windows. They would start to roll down and stop, or they would roll all the way down and then when I wanted to roll them up, they wouldn't. It really got to be a problem at drive thru windows and at the bank. I got so annoyed with it that I troubleshooted the problem online and after reading multiple complaints, one seemed very reasonable. It stated that the wire cluster feeding the driver door had a very short ground wire. It suggested pulling the black rubber wire protector thing back and inspecting the wires. Sure enough, after multiple, detailed checks, I found a black wire that had snapped in two. I found a wire connector piece in my husband's tool box and pieced the wire back together. Problem solved. It's been two months and I haven't had a problem. I'm sure it'll happen again with all the opening and shutting of the door, but now that I know the signs ... it's an all too easy fix! I'm very happy with my Impala.
