XK8 gurus,
I need to inspect and troubleshoot the driver door wire loom. How do I get the front end of the loom through the grommet and hole in the door (where the loom exits the door going to the plug connector in the door week)?

Do I pull the grommet out? If yes, how? Then push the round plug through the hole back into the door?

Thanks in advance.

I solved my own problem of removing the driver door loom from the door.

There is no separate grommet in the loom’s hole at the hinge end of the door. It is a grommet like flare at the door side of the rubber boot that protects the loom as it goes from door to the plug that attaches to the body in the door well.

To remove the wire loom, I unscrewed the plastic nut holding the rubber boot to the body (just above the door hinge) and twisted the knurled black plastic sleeve counterclockwise and pulled the plug away from its socket in the body.

I then pusjed the back side of the grommet end of the boot forward, through the hole, toward the hinge. I then turned the grommet end sideways, pinched it narrow so it would fit through the hole, and slide the grommet end back through the hole into the door.

simple once you know what to do.

Any advice on how to test the integrity of the loom without pulling it apart?

Thanks,
DrDan

 

Well done....

 

Are there any clips in the door for the door harness or can it be removed once all connectors have been disconnected?
How you investigate depends on the fault you think you have. If you think you have a broken wire you just set your meter to resistance/ohms and connect the meter to each end of the wire. An open circuit (high resistance) indicates a fault is present. A good wire should be very low, no more than 1 or 2 ohms.
If you think you have a short between 2 wires in the loom then the symptoms of the short should be giving you a clue where to start, i.e. problems with speaker. Testing for this is more long winded in that you set your meter to resistance/ohms, connect one end of the meter to the suspect wire and then connect the other end to each of the other wires in the loom in turn looking for a low resistance where you are not expecting to see one. I recommend you write down the connections/wires you test as you go so that you know what you have and haven't tested. Bear jn mind a short has probably been created with wear over time so you may need to flex the loom at known stress points, i.e. with a door harness, where the loom bends when the door opens/closes. Good luck.

 

what is a loom?

 

The big wiring harness in an engine bay is often called a loom....
