Do I Have a Burned Fuse Holder?
Do I Have a Burned Fuse Connector?
Your car has many fuses, some protect very little like a rear windshield wiper
while others protect major system circuits, like the engine management system. The primary purpose of an electrical
fuse is to help protect a
circuit from damage in the event of a short. A fuse is designed to break stopping
the voltage flow in the event of a power overload or short circuit. Each vehicle
has several fuses that are
necessary to safe guard electrical circuits. An electrical circuit will always
fail at the point of highest resistance. Most of the time that point is the fuse
holder. If an electrical circuit fails, an electric window system (for example) the first thing you
should check is the fuse.

- Step 1 - Remove the fuse and inspect, does it have
signs of extreme heat, possibly even melted? If so you have a burned fuse holder. This
condition occurs because fuses are subject to vibration and moisture. Once
the fuse is replaced the situation will occur again because the fuse holder
receptacles are burned and will create high resistance. To check for this
condition remove the fuse of the circuit involved and using a flash light
inspect the fuse holder receptacles with the plastic around them, if they
are melted and discolored they need to be replaced. There are two ways to go at this point, you can replace
the fuse panel or locate the wires involve using a
wiring
schematic
and create a new fuse component outside of the fuse panel. I have done this
many times and it works very well.
- Step 2 - Sometimes a burned fuse holder is not always
easy to detect, in this case remove the fuse of the circuit in question and
replace it with a new one. Next with the key in the "on" position move the
fuse in and out of the fuse holder and note the effected device such as
electric windows. If the device starts working while you are moving the fuse
in and out, you have a burned fuse holder and a repair is needed.
