I had a new thermo and anti freeze change on mine and still I get warm to hot at idle, but in motion when you let off the gas it gets cold. I am guessing at the sounds of all of your problems that there could be a linkage to the baffle door that lets air in. If your selector switch now spins freely it probably shook loose. Sometimes it's a cable, others a rod. Have not looked at mine so don't ask where to look, but it is reasonable, especially if it works ok in back but not front. The dealer is trying to figure mine out. Good luck!
