The eco mode on this vehicle regulates the air conditioning, heated seats, and other instruments that use power in your vehicle. By reducing the amount of power being used, it eliminates some of the load from the engine and helps improve fuel economy.
The eco mode is controlled by an AC amplifier. It is located under the dash on the driver's side. I attached pics below. Make sure the connection to it is in good condition. Also, let me know if the AC is working. If it isn't, check the heater IG fuse in the fuse box under the dash. It is a 10 amp fuse.
If the fuse is good, confirm there is power to and from it.
Let me know what you find or if you have other questions.
See pics below.
