2002 ML 270 windows and mirrors not working.

Bugger, what was recently an intermittent fault with lack of power to the windows and mirrors has now become permanent, they were sometimes taking a while to "wake up" especially in cold weather, now all are completely dead, I have checked the fuses all are ok.
Plugged in the Icar soft , when you scroll down to LCP lower operating panel (which i believe controls the windows) it says it's unable to communicate with it....
anyone got any ideas ?
Thanks.

I think, but not sure, the windows are run off the AAM (all activity module)
You might have to resort to someone with STAR

Thanks, i think you're probably right, I was hoping there may be a couple more things I could try before resorting to that.

if all windows are not working, then it points to something common with them all, which will be a module of some sort.

Success ! The module under the center console is faulty, no obvious signs of damage but when I warmed it up with a heat gun it started working. ebay here I come.....

Maybe check for a dry solder or give it a clean with contact cleaner.

Good idea, ill see how long they stay working for and maybe try that, cant be much wrong with it, just had a look on fleabay
theres plenty on there for around £50.

Just fitted the replacement window switch module (£30 off ebay) happy to report everything working perfectly. Next job, engine service before the mot in Feb.

Well done.
Was this the one that responded to warmth OR some other one..? If the latter, where was it located..?

Cheers, Yes it worked after I warmed it up (a bit) with a heat gun, when I plugged it back in it worked fine for about half an hour then it died again. It sits underneath the console between the gear lever and the cubby box, I will try and upload a photo.
