The problem here is NOT the quality of the wire, but the absence of a
protective rubber boot through which all the wires should run!! If
the boot deteriorates, the wires can rub against metal surfaces.
When you fix the wires, replace the boot, too!
OK - here are some thoughts. My suggestion is NOT going to be easy,
so I welcome others comments.....
1) Don't depend on electrical or friction tape. It might serve as
an emergency mesaure, but it may leave goop on the wires, and it will
definitely not last.
My idea involves a kind of tubing called "heat-shrink", which is
available at electronics parts stores in different sizes. This stuff
looks just like the insulation on wires, and is just as tough, but
it's just a tube. When HEATED to the proper temperature, it shrinks
to about 50% of its former diameter. It is commonly used
in electronics to cover soldered joints and prevent shorting to
adjacent wires or metal areas. Heat is properly provided by a VERY
hot air gun, but can also be applied with a match. (I have seen
propane torches used, but it's eacy to get too much heat and melt the
Here's my idea - and it wouldn't be fun.
The idea would be to pull the door panel and see if you can get at
all the wires where they pass from the door to the body. If so, the
goal is to free each wire, slide some heat-shrink over it, heat the
tubing, then re-connect each wire. This would provide a durable,
permanent insulation over the exposed area on each wire.
The BAD part - to free up the wires, you'd have to clip each one
short of the connector (to window switch, etc...) in order to be able
to slide the heat-shrink on. After completing the heat-shrink
process, you'd have to re-connect each wire. I'd probably use
butt-splices for this, as they crimp on quickly. Solder and more
heat-shrink is cleaner and more permanent.
Anyone have better advice for this gent???
