My wife's Cruze recently developed an issue with the drivers side front power seat. The base front lift has quit working. It sounds like the motor is working and it just clicks like a cam gear is broken. The bases rear lift works fine and forward/back is working fine. Before I pull the seat to inspect further, anyone have any ideas as to what to check and possible fixes? I hope parts are available, but at first glance at the parts diagrams it seems only have motors are available. I hate to buy another seat track assembly to fix this minor issue, but it is the wifey's car and I still need to replace the heating element she has been reminding about lately with the cold temps.
