is300h Mark Levinson - Drivers Door Noise

[Gossy1988]

Morning!!

I posted previously regarding a noise (which sounds like the bass has gone) from the drivers door, during particular songs.  I have taken it to Lexus who have confirmed that the speaker is working perfectly; however, the noise is a sound proofing issue. Lexus tried to fix the problem but to no avail, they did pinpont the noise down to the window switch.

Since then I have been online and seen that this particular issue is quite common with models from 2013, which have the ML speakers. There is an apparent fix, which is to take the switch out of the assembly and wrap, tightly, with electrical or felt tape. I thought "happy days" I have found a fix.... unfortunately not. I wrapped the switch tightly and even added some more sound proofing under the switch and the same noise is still there.  I can confirm it is the window switch as if I play a certain track which causes the issue, a slight press from my knee against the door panel (woodish trim with the switch) instantly stops the noise.

Has anyone else come across this issue and if so have you been able to fix it? It is very irritating. 

Thanks again.
