windshield wiper blades do a lot of shimmying and make a
heck of a noise. This is likely because I have to park
outside, and the wiper blades are exposed to the sun and
elements. I do change the blades yearly, but Iíd like
to know what types of blades are best at maintaining
their flexibility and work most quietly.
blades never seem to get much respect until itís time
to use them! Itís possible a simple cleaning, using
denatured alcohol and a towel (several wipes), or even
soapy water may help.
for the windshield, which may have built up road grime,
tree sap or other contamination, especially near the
bottom, where the wipers mostly live.
insert, the actual rubber part of a wiper blade,
typically takes a set (a slanted posture) while parked
and is subjected to heat over time. Itís slightly
possible smoother and quieter wiping could result from
reversing the inserts within each blade, if they can be
found even a marginal set of wipers can provide better
performance by applying Rain-X to the windshield,
following the directions. I really like this stuff. Also
consider premium grade blades made of silicon rubber;
they really work well and last considerably longer than
standard rubber blades, at about twice the price.
thought: Perhaps hang on to the blades you remove and
use them as the summer set. If you can avoid misplacing
the winter set, they should last for a much longer time.
battery light has been coming on at random times. The
car runs fine both when the light is on and when it
isnít. I know it wonít do it if I take it in ó
figures! Do I need a new battery?
illuminated battery light is telling you that an
intermittent charging system fault is occurring. Itís
unlikely your battery has an issue. Depending on the
vehicle, the fault may be a no-charging or over-charging
battery is like a checking account; it simply stores
energy and is used primarily to start the engine and
provide engine-off power for accessories. The
alternator, a belt-driven generator, supplies energy to
meet all electrical needs and keep the battery properly
intermittent nature of this problem will make it
challenging to diagnose the cause. Iíd start with a
simple inspection (with engine off and cold, wearing no
jewelry on hands) of battery terminal condition and
tightness, and any wiring connections at the side or
back of the alternator. Alternators are typically dull
aluminum in color, cantaloupe size, belt driven, at the
front of the engine, and likely the only such device
with wires attached to it. Wiggling all connections,
including the battery terminals, may temporarily change
the symptom, for better or worse. If the existing
alternator has 125,000 to 150,000 miles or more on it,
its brushes, the only wear item inside, may be wearing
require attention, as a charging system fault can leave
you stranded should charging not occur, or potential
damage, should overcharging beat up the battery or
certain electrical components.
