20 Most Recent 2004 Saturn ION Questions & Answers


Let's get this straight , when you turn the key to the start position ,what happens ? Does the starter engage an spin the engine ? Or not . If you what help you need to give better descriptions . You turn the key on an the dash light come on , do the warning light's go off after a few seconds ? Is the anti-theft system light on an then goes off . Do the headlamps work , an shine bright ? Viewing a wiring diagram of the starter electrical circuits to see what it takes to make the starter spin the engine would also be a good idea . It just so happens the starter is computer controlled .
Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S terminal of the starter. Ground is supplied through the engine block.

Your best bet , have it towed to a qualified repair shop.

If you have to ask it's way over your head. Rod bearings are about as deep into an engine as it gets. Best bet is to pull the engine and take it to a machine shop.

If it is a detachable face,make sure the face is on good. If not and you checked the fuses,then you need to check the wireing to the radio. FYI these late model cars have fuses under the hood as well as inside the car.

is there an easy way to reset the passlock

Check the fuse in the interior fuse box and the relay in the power block under engine hood.

The locks don't work from any switch or just the driver's door switch ? The door locks are controlled by the BCM - body control module , that's were the clicking you hear is coming from there are no fuse's that are marked for the locks , fuse's for the BCM .

Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• BCM -- Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• BCM PWR 15A fuse -- Located in the BCM fuse panel, supplies power for the door lock system

The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.

Body Control Module (BCM)

bad clockspring in the steering wheel it sounds like

What pump are you checking an fluid level ? Your vehicle has electric power steering an has no pump or fluid .
Your best bet , take it to a GM dealer , had recall on parts of the EPS , electric power steering (EPS) system .
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

you need a new stalk switch. simple as that

Try pulling the steering wheel back and forth while trying to take the key out. Or, push forward and back on the shifter while it's in park, while trying to take the key out. This could be the steering wheel lock mechanism.

If you think it needs lubrication, try a LITTLE bit of graphite lubricant. Do NOT use WD-40.

Wheel bearing or cv joint.

check trunk fuse

2004 Saturn ION | Answered on Oct 01, 2017


Very common problem. Usually the sensor in the cooling system surge tank is sticking and/or connector underneath surge tank.
