UPDATE: To answer some questions. Yes I am talking about the Homelink brand in my RAM, Audi and Honda. The sun visor remote is a Liftmaster 3-button remote. Everything works perfectly except the RAM. I am 120 feet from the road to my attached garage and 180 feet to my shop building. All will work (with the exception of the RAM) from the road.
After several more discussions with the dealer they want me to "clear" the remote in the RAM and not relearn any codes. They want me to recycle the system by driving (starting and stopping) several times in the hope this completely clear and reset the Homelink unit. Much like rebooting a computer and many other electronics that we now have to learn to live with. This is what I have been doing and will continue doing until Monday. Then I am going to go step-by-step "learning" the RAM Homelink again.
Keeping my finger crossed (I still have my doubts) and will update on how that works out and we go from there.
