Question: AC inside control panel

I can't switch my AC from EC to recirculating mode on the control panel. The compressor guage low side reads 70 psi and will not engage. Is it possible that my EC sensor under the dash is bad? Please help.

    you need to scan the climate control system and find out what codes you have. EC means "economy" and the compressor will never come on while it's in this mode. there is no EC sensor.
