Thread: URGENT: NEED HELP WITH ELECTRICAL PROBLEM ON THE ROAD

The switch pack is connected to the Driver Door Module, which directly drives the window motor and provides a canbus connection to control the other windows. So you need to investigate that module's connections and the door motor connections. The module can't be completely broken if it's still sending signals to control the other windows. However, if the other windows only work from their own switches then the driver door module could be broken.

Hi,

This is a diagnostic chart from the workshop manual. Unfortunately the formatting disappeared when I copied it. It contains a 3 column table (Sympotom/Possible Causes/Action) so if you keep that in mind you may glean some useful info. Following that table is a 2 column Pinpoint Test list that is referred to in the diagnotic table (eg Go to A3 means go to pinpoint test A3). Sorry I can't get it any better. Hopefully it will help you. Good Luck.

Diagnosis and Testing
Principle of Operation
For a detailed description of the glass, frames and mechanisms and operation, refer to the relevant Description and
Operation section of the workshop manual. REFER to: Glass, Frames and Mechanisms (501-11 Glass, Frames and
Mechanisms, Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does
not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor
vehicle.
• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify 1. the customer concern.
2. 2. Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection

Window control switches condition and installation
Window motors/regulators
Window channels/runners
Window cables
Door window glass retaining brackets
Fuses
Harnesses and connectors
Window lift relay
Window control switches
Window motors
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before
proceeding to the next step.

4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

Symptom Possible Causes Action
Window(s)

Fuse(s)
Switch fault
Front switch isolator fault
Motor/Regulator fault
Channel/Runner fault
Cable fault
Harness fault
Check the fuses. Check the suspect window operation from the
individual door switch and from the driver door master switch (it
is unlikely that both switches would fail at the same time, so if
the window is inoperative from either switch, suspect a fault
other than a switch). If the inoperative window is a rear unit,
check the function of the isolator at the master switch.
If the concern persists and a noise cannot be heard when
operating the door window glass, GO to Pinpoint Test B.

You have to remove the door trim. Have a look at the installation video to see how: DISCOVERY 4
Once you have the door trim off the connection will be evident. Then look at the clips under the switch to see how to remove it.
Assembly is the reverse.

Thank you everyone. So, here's the latest.

NRMA guy came, scratched his head, ran a few electrical tests and left. I asked him to create a temporary window in the form of a plastic sheet and he complied. After driving for one kilometre, however, I realised that his attempt would need to be optimised - at 90km/hr and higher the plastic created so much buffeting and noise that I felt like I was being blasted into space on a rocket.

Detour to the nearest shopping centre + 4 rolls of electrical tape + 1 roll of masking tape = voila! See photos attached.

Could be neater - especially on the inside - but workable enough to make 5 hours on the highway palatable. It means I can nurse the car home today and start pulling things apart tomorrow.

Interestingly enough, a highway cop overtook me at some point and I was worried that he'd pull me over and tell me to pull my contraption down before I continued. But, alas, he didn't seem to mind at all. I will take it down then I approach Sydney, however, so that I can drive safely - right now there's 0% visibility to the right.

Hi Steven - FWIW, a few years ago I was reversing my boat to the boat ramp in the rain. Some rain must have got into my switch pack - and it stopped working altogether. The dealer replaced it under warranty and no issues since. Good luck!
Cheers,
Rob

That's a great temporary window! At least it's going to get you home in one piece.
Good luck with the fault finding. Please let us know what it turns out to be.

Quick update gents,

All is good back in the hood, so to speak.

Car got towed to Trivett Sydney, they replaced the faulty window/mirror control switch bundle. I appreciate windows on a whole new level now

Good to see it's all sorted. Did they pull the old one apart & show you?
