QuestionI have a 1999 Freelander DI 1997 cc. My rear window, rear demister and rear wiper have all failed.This happened whilst I attempted to lower the rear window. When I press the window control switch I now get a short audible warning. Any suggestions please. Thanks Gareth.
AnswerHi Gareth,
I'm not too sure about this but here goes...
I looked at the Heated Rear Window techsheet and found this interesting footnote:
"The CCU will only operate the HRW when all of the following conditions are met:
The HRW switch is pressed.
The engine is running.
The tail door window is closed.
The roof is fitted (3 door models only).
NOTE: The HRW will not operate if the tail door window has not been calibrated. For more information on tail door window calibration, refer to the Windows section of this manual.
So I followed the trail to the Windows section and found this:
...
Tail Door Window
The tail door window is opened and closed by using the non-latching switch mounted on the centre console, below the radio/cassette player. Tail door window operation is controlled by the Central Control Unit (CCU), and will only operate when the ignition switch is in the 'ignition' position.
...
If the rear wiper is operational, the tail door window will not lower until the wiper is on a downward stroke. When the window is in the lowered position, wiper operation will be suspended. The tail door window will be disabled if any of the following occur:
The soft back is lowered.
The soft back is removed.
The hard back is removed.
...
I'm not sure if the above will help but it does point to possibly the following adjustment:
Tail Door Window Calibration
When the CCU is changed from transit mode to a valid market mode, and after the vehicle battery has been disconnected, the tail door window must be calibrated to provide the CCU with a window position datum.
When the CCU mode is changed to a valid market, or the battery reconnected, the CCU automatically begins the calibration process by energising the down contacts in the window lift relay module until the window lift motor stalls, to ensure the window is fully down.
The calibration procedure is completed as follows:
1. Ensure the tail door is closed, the vehicle unlocked and the alarm disarmed.
2. On three door models, ensure the roof is on (hard back) or lowered and secured (softback).
3. With the ignition on, use the console switch or the vehicle key in the tail door lock to raise the window until the motor stalls with the window fully closed.
4. Switch off the ignition.
NOTE: If the calibration procedure is unsuccessful, the CCU will sound a warning for approximately 0.8 seconds and fully lower the window.
Perhaps the recalibration will 'reset' everything and clear up your problems. Otherwise, it looks like the CCU is faulted or you have an electrical short somewhere.
Best of luck,
