I converted Max from crank windows to power windows by buying all the appropriate stuff. New door handles in place and window regulators installed. In order for the window buttons to operate the windows there is a module that needs to be plugged in. It has VDO on the sticker of it and I guess it is called a door module and it controls the power door locks also. I have the 2008 Fortwo tech manual that has a diagram of all the modules and their locations in the vehicle. My first problem was since I only had power door locks and crank windows would I have the module already on the vehicle? If so the windows don't work. If I don't have the module there should be the wire connectors already in place because the window buttons and regulators already had the appropriate wire and connectors in place. I should have some type of module because it is needed to operate the door locks. I dropped the Sam down and even removed the driver seat so that I could get my long frame laying under the dash. I cannot find a trace of a module or the connectors. There is a surprising amount of space under the dash above everything. I found the TMPS module and I know where the SRS module is because I replaced it but the door module is eluding me. Does anyone know the exact location or have a picture of it? DCO
