06 Lincoln Navigator liftgate opens okay but need help to close why?


Power Liftgate
The power liftgate feature will allow the customer to automatically OPEN or CLOSE the liftgate by activating the interior open/close switch, the remote keyless entry transmitter or by manually initiating liftgate movement. The power liftgate uses a power cinch system to latch the liftgate.
The power liftgate system consists of the following:
  • Power liftgate control switch (located in the overhead console)
  • Power liftgate motors (located in the rear headliner area)
  • Optical sensor and power liftgate encoder wheel (located in the left power liftgate motor assembly)
  • Pinch strip switches (located on the body by the liftgate)
  • Home position switch (located on the cinch actuator)
  • Forkbolt switch (located on the cinching latch assembly)
  • Detent switch (located on the cinching latch assembly)
  • Liftgate close chime module (located in a unit external from the power liftgate module)
  • There are a lot of electrical switches an motors
  • Visual Inspection Chart Mechanical Electrical
    • Power liftgate motors
    • Power cinching latch and linkage
    • Power liftgate pinch strip switches
    • Liftgate and liftgate hinges
    • Liftgate assist cylinders
    • Liftgate strikers
    • Exterior release handle and linkage
    • Liftgate weatherstrip
    • Liftgate alignment to body and striker

Subwoofer blows fuse


Short circuited component/s at its circuit board. Check and replace it. Check for shorted component/s at the amplifier stage circuit. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

The running bords on my 2008 Yukon stop working


Circuit/System Description
The assist step control module (ASC) controls the running board actuators to extend or retract the running boards. Each actuator consists of an electric motor and a potentiometer. The module supplies a low reference and 10-volt reference source voltage to the potentiometer. The ASC control module monitors the voltage drop across the potentiometer on the position signal circuit. When the actuator shaft rotates, the voltage on the position signal circuit changes. The ASC control module supplies the actuator motor with a 12-volt control circuit and a ground control circuit. The ASC module controls the direction of the actuator by changing the polarity of the control circuits.
You should take this to a ASE certified repair shop that has the diagnostic tools to check for stored DTC'S in the running board control module . A code reader for check engine light codes will not work for this system !
This system can set numerous DTC'S

How do I reset lift gate on 2004 lincoln navigator. It doesn't open or close anymore with the remote


Maybe your key fob needs a new battery !
Power Liftgate Initialization

NOTE:If the power liftgate system is turned OFF in the message center, the system cannot be activated with any switches or with the liftgate handle. The system will need to be turned ON for any power operation to occur.

NOTE:The power liftgate may not operate under the following conditions:

  • a low voltage or dead battery.
  • a disconnected battery
  • a power liftgate that has been left open for more than six hours.
  • a power liftgate that has been manually closed and left ajar.
If any of these conditions has occurred, the power liftgate must be reset.
  1. Manually close and fully latch the power liftgate.
  1. NOTE:If the power liftgate does not open during this step, refer to the symptom chart to diagnose the power liftgate for no operation.
    Power open the power liftgate by using the keyfob or overhead console switch.
  1. Once the power liftgate is fully open, close the power liftgate by using the keyfob or overhead console switch.
    This system can also set DTC'S

The fuse of Jamo Sub-200 gets blown off. is there anyone who might know the reason. thanks


try replace the blown fuse with ampere and check the sound if still ok.
some fuse got blown if the load current exceed. maybe high volume can cause the high current.
other cause by short circuit coming from the amplifier.

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

Electrical short in the subwoofer


You're quite right when a fuse blows there's a short. The short will be in either the power supply section, or the main amp. You will be looking for a semi-conductor of some sort. A multi meter on the ohm setting will track it down quick if it's a transistor. As the meter scale will be just like you have touched the probes together. Follow the circuit back from the fuse. Check any part that you suspect. If the sub uses an IC power amp, it could be a strong suspect!

More likely to have shorted out Class D amplifier module that was badly designed.

Audiosource AST-Sub 10 subwoofer. it blows the fuse when turn on.


It sounds like your audio amplifer has a short (probably the out put transistors or module). This should not be an expensive epair.
To check your speaker you can use an ohm meter. First, pull of one of the two wires that connects at the speaker. You should read 4 to 8 Ohms. Also you will hear a little pop through the speaker as you touch the wire. You can also use a 9 volt battery in the same way.
Good Luck
