So it finally got cold enough here in Florida for me to use the heat instead of a/c. But when I turned the temp control from blue to red on the driver's side, the temp changed on the passenger side. When I adjusted the passenger side temp control I got the warm air on the driver's side. They are apparently reversed for some reason.

Anyone run into this situation, and if so, how to fix without taking apart the entire dash?

 

has your dash ever been apart? IIRC, its just about impoossible to reverse connections on the HVAC controls, but thats a real interesting occurrence!
