Help! power widow/mirror switch NOT working.

I have a 2006 325i E90, tried to install HID kit but it didn't work, the light kept flickering so I removed it right away then I noticed that the power window/mirrors master switch stopped working, checked alldatapro and found a a bulletin that basically says if the headlight wires have any corrosion the master switch will stop working so I checked all the wires and connections and they all looked good, checked all the fuses and they are ok, tried to check the ETM but the one in alldatapro for this car is useless, tried a brand new switch and that didn't work nether. Any ideas PLEASE
