The battery is brand new......replaced it to make sure. The infrared light blinks when the button is pushed. You can't see it with your naked eye but can be viewed with a cell phone camera. I eliminated all possible causes on the documentation I received from Forest River that I posted earlier. I can turn the lights on from the control panel, push the "on" button on the remote and I can adjust the lights. If I push the "off" button on the remote while the lights are on I lose all function of the remote. I can then turn off the lights from the control panel and start over.
It's a brand new TT, just picked it up last Friday. I have talked to the dealership and it is under warranty but I would have to bring it back to the shop. Was hoping to fix this on my own instead of tearing it back down, getting it re-hitched just for a light issue. At least now I have function of the lights..........good enough for me for now.
