A correctly operating windshield wiper-washer
system has a spray pattern that cleans
75% of the wipe
pattern (Fig. 21) within ten wiper cycles.
If the nozzles become plugged, apply air pressure.
If nozzle remains plugged, the nozzle must be replaced.
If the spray pattern is too low or too high on the wind-
shield, wedge-type adjustment shims can be used.
Placement of a shim under the nozzle mounting bracket
will raise the pattern three degrees. Reverse installation
of the same shim will lower the pattern three degrees.

GENERAL DESCRIPUION
RADIO ANTENNAS
For radios and radio use see the "Radio Fixed Antenna
Operation" section. ETR means 'Electronically Tuned The
fixed antenna on the right front fender
Receiver'. cannot be adjusted up or down. It may provide
improved reception in rural areas.
- The fixed antenna is designed to withstand most
car washes without damage. If the antenna becomes
slightly bent, you can straighten it by hand. The
antenna can be replaced if severely bent (by vandalism,
etc.). Antennas must be kept clean for good
performance.
RADIO
Because radio problems are normally repaired at
authorized warranty repair stations, the tendency is to
remove the set when a problem is reported, without any
preliminary diagnosis. This results in a large number
of radios being "No Trouble Found" units when
received by the warranty repair stations. Often the
trouble can be corrected without radio removal. wire.
If equipped with
A/C, the blower motor has a
built-in capacitor. Extra electrical equipment added to
the static if not properly grounded or wiring was
improperly routed.
Weak
FM station reception will be affected by
nearby buildings, car speed and direction. These
"flutter" and "fading" conditions are characteristic of
weak FM signals.
ETR radios require clock and button reset if the
battery is disconnected.
Popping Noise
Static and Noise Operating devices such as turn signals, pushing in
cigarette lighter, operating stop lights, etc., may cause
Ground strap connections must be clean and
a popping noise on distant (weak) AM signals.
tight, spark plug cables must be TVRS type and in
good condition and resistance-type spark plugs used.
Preliminary Diagnostics
Capacitors are used in the generator, heating/air
conditioning system, and fuse panel to reduce noise
The inconvenience of driving without a radio
entering the radio through the feed wires. If the car has
while the set is being serviced can often be avoided if
a heater only, the capacitor is in the blower motor feed
