Re: Re: Audi rear wiring loom
Pat,
Your theories may be valid, but IME with broken wires in the driver's door,
even a wire between the window switches and the window motor will not catch
the insulation on fire if holding on by a single strand. Sure, there will
be arcing and all sorts of funny errant current in the car's electrical
systems when there are broken wires - as shown in many Type 44's when a
license plate bulb burns out and the dash lights don't come on, or type 43's
where corrosion in the turn signal housing causes the dash lights to flash -
but I dare say that I have yet to hear about a single car burning up because
of broken wires in the trunk lid or door jambs. The Bose speaker fires were
something different - involving the failure of components of the amplifier
which was mounted the rear speakers. See:
http://members.aol.com/c1j1miller/radio.html
You can also see the response of Audi (of America)...or, rather, non
response. They dragged their heels on the issue while companies like Nissan
recalled their Bose equipped cars. Look at the pictures - now that's a
fire!!!....but it doesn't have anything to do with work-hardened wires.
My suggestion is that if you have a good light bulb in the car that won't
come on, or an electrical feature that doesn't get power - it's time to dig
out the multimeter and a set of good crimping tools and check the hinge
areas of all doors and the trunk lid. Use the Bentley Manual wiring
diagrams to help you trace things. Remember that if it's something like a
sunroof motor that's away from the doors, it may still be powered through
the driver's door jamb.
If you spent $$$+ buying an Audi wiring harness......well......the money's
spent - don't expect Audi to comp you a harness or two.
