2. Check the metal tubing lines to be sure they
are free of dents or kinks which can cause a
loss of system capacity due to. a line restriction.
3. Check the flexible hose lines for brittleness or
deterioration which can be the source of a
system leak.
4. Check for proper drive-belt tension.
Operational Quick Checks
The following checks may indicate if the amount of
refrigerant (charge) in the system is low. The ambient
temperature must be above 70°F.
NOTE: Engagement of the compressor clutch in
both of the tests below indicates that the clutch
electrical circuit is OK. If the clutch does not
engage, then check for a blown fuse, loose con-
nections or damaged or deteriorated wires. If
these checks are OK, then the problem may be
in the compressor clutch or switch. Take the vehi-
cle to a qualified shop for further testing.
Vacuum System Diagnosis
If the air is not flowing through the proper outlets
(floors, dash, or defroster). then there may be a prob-
··Iem in the vacuum system, or with the diverter doors.
Check the doors to see that they operate properly and
do not bind.

Next check all vacuum hoses and connections be-
tween the vacuum source, AIC control and vacuum
motors for leaks. If any hoses are damaged or deterio-
rated, they should be replaced. If the hoses are OK,
the problem may be in the control assembly or vacuum
motor(s). Take the vehicle to a qualified shop for further
testing.
Electrical Circuit Diagnosis
The blower electrical circuit and motor is OK if the
blower operates at all of the designated speeds. If the
blower does not work at all, then check for a blown
fuse, loose connections, and for damaged or
deteriorated wires. If these checks are OK andlor the
blower does not operate at all speeds, then the prob-
lem may be in the switch, relay or motor. Take the vehi-
cle to a qualified shop for further testing.
STEERING AND SUSPENSION SYSTEM
Front Suspension and Alignment
The term "front alignment" refers to the angular rela-
tionships between the front wheels, the front suspen-
sion attaching parts and the ground.
The pointing in or "toe-in" of the front wheels, the
tilt of the front wheels from vertical (when viewed from
the front of the vehicle) and the tilt of the suspen-
