Wiring short. You'll have to replace the wire.

2007 Saturn ion 3 door locks fuse location


Power door lock's are controlled by the BCM - body control module . Are you familiar with automotive electronic's ?
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
• Body control module (BCM)--Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• Body control module PWR 15A fuse--Located in the body control module fuse panel, supplies power for the door lock system

Door Lock and Unlock Operation
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 1.5K ohm resistor 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.

My right side passenger door does not lock automatically anymore. Is there a fuse that operates this.


no all is related to one fuse you can remove the door internal controls and decore and remove center lock motor plug and test two connectors with multimeter with set on 12v and then lock un lock door and check the reading of the multimeter if it read signal then all plugs and wires from central lock control unit to the door central lock unit is okay it this cae you have to replace the door central lock unit with the same if no signal is readed while you lock unlock the door then you have to check central control unit and all wire plus out of it to the door plug

2- you can remove central control unit from driver door and test it in passenger door (usually the same unit ) if it works with lock unlock its then the replaced unit is faulty and needs to be replaced if it not work then check plugs wires from central lock unit (usually found inside driver door ) to the central lock unit in passenger door

3- check signal for said door fro the output of central door unit if no signal then it mean that faulty central lock control unit

The automatic locks are not working and the turn signals are no longer blinking. They just stay lit. I have checked the fuses, and there doesn't seem to be a problem.


the turn signal issue is just the flasher unit has gone bad , check under the dash in the fuse panel area for the flasher unit, It just unplugs and you plug the new one back in,
  1. If there is only ONE door lock not working, the problem is more than likely isolated within that particular door, barring some unusual wiring issue.
  2. If all the door locks work with the passenger side door lock switch, but not the driver's door lock switch then the problem is more than likely the driver's switch.
  3. If a single door lock only works in one direction, either to lock or unlock but not both, then the problem is likely to be the door lock actuator.
  4. If ALL door locks work only in one direction, ether to lock or unlock but not both, then the problem is likely to be a bad door lock switch.

Remote door locks won't work


There is a flash for the body control module for this problem. You need to go to the dealership to get it performed though.

You have a short Somewhere. Check inside the Door where the Harness goes into the Doors. It is the Black Flex duct that looks like a Vacuum hose.
