Mine did the same thing. Diconnect the Positive battery cable. Leave it off for about 5 minutes. Reconnect and your system will reset itself. Get in and watch the numbers cycle. Don't start your car until the cycle is complete. If it resets but reverts bach to the "econ" thing then you need to charge your system (Freon).
there is a module that controls the motor located arend the blower moter that will need to be replaced. Not sure if this is available other than dealer. check with auto parts stores first. I would ask for blower motor control module.If this helps please reply and good luck
You should make sure you have proper charge for sure.has your battery gone dead lately? I know on some of them digital climate controls will act exactly like this and have to be reset or go through a setup sequence.
The linear actuator that regulates the blend of air between hot and cold was broken and needed to be replaced. That was my suspicion. Fuses were all good. Relays were all good. Compressor pump cycled. Freon was "proper". Dealership only charged about $400 in parts and labor to confirm my guess.
