The default to econ, is usually from another HVAC fault, other than a blower motor. Something like low refrigerant, or false detection of due to a faulty sensor. The blower is more than likely a blower.

Remove the blower wire. It goes back to the blower motor module its bolted into the top of the a/c case. Replace it. The auto light is a whole other problem I think but lets start her. Ty for using 2carpros
