lucerne master switch replacement
I replaced the master switch for the power windows etc. in his 2011 lucerne and now nothing will work like the computer doesn't see the new switch. I'm sure there is some magic keystroking that has to performed but have been unable to get that information. If anybody knows the magic potion I would be real happy if they shared it with me. Checked all the fuses and that's not the problem plus all the other door switches work. I know my BMW and other cars require power windows syncing under certain circumstances. Poor buy spent $240 for this switch and it won't do anything.

A little FYI,
When a request is sent to a driver's door module for something to be done, that module sends that request to the Body Control Module which sends the order to the component that does the job. All this communication is sent along a CAN network and when something is disturbed or a part replaced , the network has to be updated,notified, of the change. This requires a special,capable, scan tool to do this.
Access to the info , the correct tool, and knowledge how to use it are required . Until this is done the system will not recognize the part and many times reinstalling the original part will no longer work either.
The days of trying to help ourselves are gone and we need to accept that.
So as you can see, there are several places that could have lost the request or the order and most likely a good part could have been replaced when it was not the problem unless it was proven to be defective.

Carl, all the power to you !
Maybe a little info might help looking at it from a different angle.
Even if you managed to get the starter to turn the engine over , the coils will not fire, and the fuel injectors will not work.
Do you still want to play around with that?
They have made it IMPOSSIBE to do much work without having access to the info and the special tools. I believe they call it progress. A shop has to pay for a subscription to even get the info and it "ain't cheap.
