Mercedes-Benz C320 rear window won't go up after going down on Mercedes-Benz C320

Some Mercedes-Benz C320 owners report experiencing issues with the rear window not going up after being rolled down. These problems may stem from a faulty window regulator, which can prevent the window from functioning properly. Additionally, electrical issues such as faulty switch contacts, a defective switch relay, or a malfunctioning regulator motor could contribute to the window's failure. The power window pinch protection feature may also cause the window to reopen if it detects resistance while closing. Furthermore, if both the window and seats are unresponsive, it is recommended to check the fuse for the door control module, as newer models have protective mechanisms for the window circuit. Lastly, some owners encounter synchronization issues if the window only rises slightly with each press of the switch. It is advisable to investigate these potential causes to effectively diagnose and resolve the issue.
