Question about 2007 Jeep Liberty Sport

2 Answers

Battery draining while I am at work, both day and night. I tool it to one mechanic and he said it is the jb7 fuse. I know it works the door locks and radio. What else does it work? How do I find out which accessory on that fuse is causing the problem? Do I have to take it to a dealer?

Just google it

year make model fuses

and then look at the images tab.

You need a good auto-electrician to trace parasitic drain.

You either need to do a current draw test on every circuit or find a decent electrical mechanic. the dealer may not be one in this case.

SOURCE: cant get the factory alarm to stop going off .

Look up drivers side dash to the left look up should be a little box with wires, unplug one at a time make sure the truck starts after each wire unplugged. My nephew had the same problem on his Jeep. Alarm is tilt sensitive. Neighbor had the same problem on his GMC.

SOURCE: power windows, locks, dome light, and remote locks not working

Try checking the ground wires. They become corroded or loose and crazy things begin to happen.
Battery to frame and body to frame.
Be sure they are clean and tight.

SOURCE: I have a 2002 jeep Liberty.If i leave #23 fuse in

Just for thought try removing the light bulb under the hood, the socket my have gone bad and keeping the light on.
Good luck and keep me posted. Also not sure if your Liberty has one of the sun visor with a light switch on it, I found the one on my jimmy was always on thank's to my G/F putting things between the visor and ceiling.

the fuse box is behind the battery and the opening clip is between the box and the side panel, the ECU fuse is a 20 second row from the bottom, the blow pretty easy

2007 Mercury Grand Marquis LS lock switches don't work including the truck. The other switches work find.Keyless entry doesn't work either.

Do you know anything about automotive electronic's , control module's etc.... work including the truck.???? trunk ? Electronic control module ( DDM ) driver door module control's lock's an power windows . Do you have a professional or factory scanner to test for DTC'S - diagnostic trouble code's ? Do you know what diagnostic pin point testing procedures are ?
Power Locks
The power lock/unlock feature requests all of the vehicle doors to lock or unlock upon a request from the door lock control switch, the RKE keypad, or the RKE transmitter. Power locking and unlocking functions independently of the key position, vehicle speed, or transmission position. The LCM and the DDM activate internal relays to supply the correct power and grounds for the door lock actuators
The DDM receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, door lock control switches, lighting control module (LCM), RKE keypad and RKE transmitter. The DDM outputs consists of RKE keypad illumination, door lock actuators, luggage compartment lid release solenoid, and the LCM.

Inspection and Verification
WARNING: If equipped with fire suppression system, refer to Section 419-03 for important safety warnings.
NOTE: Before starting electrical diagnosis, check for mechanical binds by manually operating the door locks. Operate the lock system several times from each switch while observing the operation of all the door locks. Be sure the battery is fully charged.
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart Mechanical Electrical
  • Binding latches
  • Battery junction box (BJB) fuse(s):
    • 8 (20A)
    • 103 (50A)

    • 601 (20A)

  • Luggage compartment lid release switch
  • Luggage compartment lid release solenoid (part of the luggage compartment lid latch)

  • Driver door module (DDM)

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If diagnostic tool responds with:
    • SCP or ISO circuit fault; all electronic control units no response/not equipped, refer to Section 419-10 .
    • No response/not equipped for the DDM, refer to Section 419-10 .
    • No response/not equipped for the LCM, refer to Section 419-10 .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the DDM and LCM.
  1. If the DTCs retrieved are related to the concern, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

Battery in my 95 sable wagon keeps draining after a few day's of no use. The battery and alt are good but the wiring from the alt to the battery is old, what is that wire called so I can replace? Also my...

That wire would be called a primary wire. You are probably correct about the door locks.
First, go to a Autozone or Oreillys and ask for a free scan for your system. Tell them about your battery concerns and the primary wire. Their gauges will show if the charging system is okay.

Next, try to look in a owners manual for the fuse diagram. Autozone may assist in giving you the info. You want to know what is on the door lock circuit. The idea is, if the fuse to the door lock was removed, what other things stop working? If you can operate the car without those things then pull the fuse and see if the battery goes down. If you can not operate the car with the missing items, pull the fuse overnight and replace it before you drive. Again if the battery is okay you have isolated your problem to the things the fuse controls.

Then you can start looking for the one source of the problem without needlessly tearing up your car. This may be a wire in the door or door lock button.

Brand new battery is dead with nothing left on. Bad ground?

Remove positive battery terminal from battery & put a 12 volt test light in line between cable & battery post. As long as 12 volt light is illuminated, you have a draw. Start pulling & re-installing fuses, one at a time,until you see it dim or go out. If it goes out, you found your draw. If it dims, slight draw, such as radio memory etc. if all else fails, make sure you know where they all go, then pull them all, and start putting back one at a time. When light comes on bright, you found the circuit causing the draw.

2000 Ford Focus automatic door locks quit working. Replaced Central locking module, but still does not work. All of the doors will only work manually. Remote works to open trunk only - will not work on...

check fuse 63 first.

Visual Inspection Chart Mechanical Electrical
  • Binding latch mechanisms
  • Binding linkage
  • Misaligned door
  • Central junction box fuse 63 (20A)
  • Damaged wiring harness
  • Loose or corroded connection(s)
  • Circuit
  • Door lock switch
  • Door lock actuator

It could also be your GEM (generic electronic module) which is expensive as it controls a lot of stuff. A scan tool can be used to cehck for fault codes from the GEM.

Battery dying every 3 days

I have two comments to make about the drained battery that we found out...

1. The On-Star system stayed on when its suppose to shut-off once you shut off the engine and open the door. The green lite on on the unit is really hard to see during the day, but easly at night. I let the car sit over night and the next morning the unit was still active... hence draining the battery. The On-Star is using the same fuse as the dome lights. So to reset... with the door open pull the fuse, close the door insert the fuse, you should here a relay switch click. Open the door a wait for the dome lights to come on... the On-Star unti will not and should not unitl the car is started. You may need periodically keep on eye on this.

2. The other related problem is the radio fuse which is also identified as a battery guard. Not sure what that means or does yet... but the radio on-off situation seems to have started when I didn't replace the battery cover, so I'm wondering if the negative terminal is shorting out on the car. I'm getting a new cover to see if this corrects the problem... I know its sounds strange but why is there a battery cover to begin with.
