Hi, on my ML270 there is no air coming out of the dashboard centre vents. The outer vents are working okay. Can anybody help or point me in the direction of a post that deals with the same problem? I have removed the Instrument cluster, stereo and glove box but I cant remove the walnut stereo fascia panel and cant see how to get to the back of the vents to see whats happening. Any help would be much appreciated! Thank you
