I am concerned about the moisture I found, it was unexpected as the carpet seemed dry but the sound deadening material between the carpet and the floor seemed saturated. Not really sure where the moisture source is yet.
I tried again to disconnect the module and I can see a tab in the center of the connector that appears to be the release but no matter how I manipulate that tab I can not get the connector off. Given the problems I am having sourcing a replacement I plan to leave it in place.
I took a picture of the controller corrosion, pretty sure it shows why the module is not comminucating.
