Cadillac DeVille driver's seat adjustment control malfunction due to discontinued electrical switch on Cadillac DeVille

Some Cadillac DeVille owners report experiencing issues with the driver's seat adjustment control due to a discontinued electrical switch. These problems often involve verifying the power supply to the switch, as some owners find that the orange wire may not be sending power to the seat motors. Additionally, inspecting the electrical connections under the seat is crucial, as a loose connector can hinder the operation of the seat motors and heating elements. Owners have also noted that obstructions or debris under the seat can prevent proper functionality, necessitating a thorough check for any items blocking movement. If there is no motor noise when using the switch, it may indicate a fuse issue, a malfunctioning motor or linkage, or an obstruction. Furthermore, some owners report that if they can hear the motor but the seat does not move, the problem might be with the plastic drive gear in the gearbox or the lever assembly, with the gear being a common failure point. Prompt attention to these issues is recommended to restore functionality to the driver's seat adjustment control.
