OK, here is the fix. There is a small control module that is bad and located under the rear headliner and near the antenna base. Honda part # (78300-T0A-A01). Cost is around $45-50 depending on what your dealer is willing to discount. To replace just remove the rear drivers side trim plate that is next to the headliner and then the dome light cover and the two bolts and then carefully pull down the headliner to expose the small module. The module is attached with a plastic plug on one side and a 10mm bolt on the connector side. Not a super easy job but not that difficult. There is a youtube video online that is for replacing a damaged antenna base that shows the steps to get the headliner lowered.
