Why is it my 2008 chevy uplander rear wiper motor/blade moves some and stops. I let van set 5-10 minutes with key off. Turn on key. Wiper motor/blade moves a few degrees and then stops again. Why?


Can you move the wiper by hand ? Which does your vehicle have ?
WDA/Z88 The rear wiper is controlled based on an input from the rear wiper/washer portion of the multifunction switch. When closed, the wiper ON and wiper DELAY switches provide a unique voltage signal to the rear window wiper motor indicating the desired speed. Each switch has a unique resistor that drops the voltage to a specified value which is interpreted by the rear window wiper motor as ON or DELAY. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).
W49 The rear wiper is controlled based on an input from the rear wiper/washer switch. When closed, the wiper ON switch provides a voltage signal to the rear window wiper motor indicating rear wiper operation is requested. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).

My trunk will not open. When I take off battery cable and replace, it opens once. Is there an easy fix? relay etc?


When the rear compartment lid release switch is pushed, the rear compartment lid release signal circuit to the body control module (BCM) is grounded. BCM then grounds the coil side of the trunk release relay through the trunk release relay control circuit. With this voltage is applied to the rear compartment lid release actuator, opening the rear compartment.

My rear view mirror camera quit working I checked the fuse it's good the backup lights work.Help


Circuit/System Description
When the transmission is placed into REVERSE, a 12 volt signal is sent to the rearview camera image display module indicating that camera operation is requested. The rearview camera image display module then supplies ignition voltage and ground to the rear vision camera. The rear vision camera sends video information through the rearview camera image display module to the inside rearview mirror through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.

Hi i have just changed steering wheel on fiesta zetec 2003 for a ST150 2005 steering wheel will the air bags and connections be compatable with each other.


. Were did you check for codes ? an what are you checking with ? you need a factory scan tool to check for those type codes ? or the light flashes codes
Lamp Fault Code (LFC)
When the RCM detects a fault, it will cause the air bag indicator to flash a coded sequence called a LFC. The code is one digit. The digit is indicated by a number of flashes with a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indicator will remain lit as long as the key remains in the RUN position. If there are multiple LFCs, each LFC will flash in order of priority.
Each LFC has one or more associated DTC.
  1. Press TRIGGER. The RCM will run the On-Demand Self-Test and display On-Demand DTCs (reflecting hard system concerns) on the screen.

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

Testing on and off vehicle Denso alternator 104210-3762


to test on vehicle have engine running and put a voltmeter across the battery poles , this will give you the charge rate , bench testing would require specialist equipment to be able to get the alternator running , if in vehicle test is done then can't see the need for bench test other than condition of bearing, contacts etc, hope this helps
