Eliminate Windshield Wiper Blade Motor/Transmission Noise
There is nothing as annoying as noisy wiper blades. Like nails on a chalkboard, the sound can drive you out of your mind as you cruise down the road. From a dirty windshield to a wiper assembly that is too tight or loose, there are many different sources of wiper noise. As awful as it sounds, listen closely and try to determine where the sound is coming from. If you hear noise coming from under the cowl of your windshield, your wiper transmission and/or motor requires attention. The following steps will help you cure the noise and give you a quiet ride.
1
Position the wiper
blades at the top of the windshield.
2
Using soap, mark the
blade position on the
windshield for future reference.
3
Locate and squeeze the
tabs or caps at the base
of the wiper arms; if
nuts are present, remove
them.
4
Carefully lift and wiggle
the wiper arms off the
splines.
5
Next, locate and
remove the screws
holding the cowl in
place.
6
Remove the cowl, to expose
the weather stripping,
wiper transmission,
and wiper motor.
7
Turn the wipers on and
listen for the noise. If it
is coming from the joints
of the transmission,
spraying with lubricant
may solve the problem.
8
If the noise is coming
from the motor, remove
the weather stripping,
unplug the motor
connector and replace.
Replace the motor by
removing the retainer
screws; remove the
retainer nuts to change
out the transmission.
9
Remove the cowl, to expose
the weather stripping,
wiper transmission,
and wiper motor.
