car runs now but lights stay on, windows don’t operate, and turn signals don’t work. Is there a way to diagnose a faulty footwell module? Mine was installed 500 miles ago in late October at dealer, so I’m surprised there would be an issue but I have been working on the car a lot since then.

 

Inspect the FRM connector pins for water intrusion, damage and/or corrosion.

 

I called the dealership that did the recall work on the FrM in October and they said it was fine. They didn’t replace it, they added a plastic shield to it and checked roof drains. They said it is under extended warranty to 186k. But I shipped it to CA for programming ($60) and a week later got it back. Installed and works fine. Not sure how I messed it up but apparently very common and not always related to water damage.

 

Glad to hear it's fixed!
