There is a couple possibilities for the ec light coming on and not switching off.1-low freon level-possible leak. 2-evaporator temperature sensor- one way to tell is if the a/c comes on and then shuts off after 10mins-this will happen every time the key is cycled.3-the actual a/c push button assembly is faulty.

Where is the fuel cutoff switch in a 2004 nissan quest? The car is not transferring the gas through the plump. It did yesterday. And now you cannot hear the plump. I just want to turn off the fuel cutoff...

i know that the previous gen quest had the fuel inertia RESET switch on the driver side kick panel...

fuel is cutting off via the ECM for your generation though

"If the engine speed is above 1,800 rpm with no load (for example, in neutral and engine speed over 1,800 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed. Fuel cut will operate until the engine speed reaches 1,500 rpm, then fuel cut is cancelled."

E404 error code?

P0404 Dodge - Exhaust Gas Recirculation Position Sensor Performance Early Exhaust Gas Recirculation (EGR) systems component s include and EGR Valve, and Engine Control ?odule (EC?) Controlled Vacuum Switch Valve or EGR Solenoid and an EGR Vacuum ?odulator. Depending on the engine and driving conditions, the EC? will control the EGR Solenoid which will operate the EGR Vacuum ?odulator to regulate the opening and closing of the EGR Valve.
The EGR system on recently built vehicles uses a step motor to control the flow rate of EGR from exhaust manifold. This motor has four winding phases. It operates according to the output pulse signal of the EC?. Two windings are turned ON and OFF in sequence. Each time an ON pulse is issued, the valve opens or closes, changing the flow rate. When no change in the flow rate is needed, the EC? does not issue the pulse signal. ? certain voltage signal is issued so that the valve remains at that particular opening.

Problem with the EC light staying on after repairs were made to the air conditioning system. Can press the EC button and hold for a few seconds and the light will go off and the compressor will kick in....

The pressure/ temp switch on the reciever drier is what the system uses to determine if the system has enough freon. Most likley cause assuming system is properly charged. You can pull actual values through the a/c push button module. If you cannot see an erratic value your best bet is to have the system scanned for codes.
