It is not the fuse and it is one module for the seats under the driver seat which I will check the connections first before I get another. The question is does it have to be programmed or is it plus and play ?You may want to check the fuse, I believe on this model it's under the hood so check your owners manual. The other cause is the Heated Seat Module which is known to also go bad and I think on the Lacrosse is separate from the other seat functions.
So in other words if it's new then no need to program but if it came used and or from a junkyard it will need it or it might just work?As it was already in the car and it's not matched to any car number it should be plug and play. The only thing I would maybe recommend, especially on newer cars electronics, is pull the battery cables when installing it and key start it the first time to try them out.
Okay. thank you. I will give it a shot and post the resultsFrom the same make and model or at least same part# yes. I'd be a little worried about a used module from some posting on them having to be replaced. But if it's a warranty type item it may be worth a shot.
