Any update on what the parts are that fix this? Seems like it is either a sensor or a blend door gear. Mine I found is blowing hot from rear vents only this spring and is out of warranty. These are going to be costly to take to dealer and pay for. At least if I can cut a plastic HVAC case panel off and glue it back closed or replace the sensor easy without pulling doors and dash. Going to be a lot of people that cant swallow a $4-5k dealer labor bill to fix this common issue. Would love to see more detailed pics of the console and if there is a heater core in it. I may just try to block the console heater core too.
