Good morning, I am working on a 08 C300 4 Matic. The driver side window switches failed, determined it was the Door Control Module and they worked for about 15 miles then nothing once again, I can "reset" the DCM by removing the power plug and reconnecting and they work with no issue but only to fail again a short time after. It would do this with the OEM and the used one I recently purchased. Any thoughts? Thanks, Casey
