Problem overview

Some Mercedes-Benz CLK320 owners report experiencing issues with window operation due to the fragility of the plastic window switches, which are known to break easily. These problems can result in the window switch failing to make proper contact, preventing the window from functioning correctly. Owners may find that the window only moves a small distance up or down, making it difficult to fully raise or lower the window. In some instances, pressing the window switch multiple times may allow the window to advance inch by inch, indicating a potential malfunction of the switch or related components. Additionally, difficulties such as the window moving in the opposite direction or getting stuck open may signal underlying issues with the switch or window mechanism. To resolve these concerns, owners should also consider the condition of the power window motor, power window regulator, or control module, as these components can significantly affect window functionality.
