Electrical Circuit Diagnosis; Vacuum System Diagnosis; Refrigeration Section; Front Suspension And Alignment - Fleetwood Bounder 1989 Owner's Manual

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
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 'notwork at all, then check for a
blown fuse, loose connections, and for damaged or
deteriorated wires. If these checks are OK and/or the
blower does not operate at all speeds, then the pro-
blem may be in the switch, relay or motor. Take the
vehicle 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 pro-
blem in the vacuum
system~
or with the diverter doors.
Take the vehicle to a qualified shop for further
testing'.
RefrigeriitionSection ..
NOTE: Excessive or unevenly distributed loads
also affect ride height and alignment. This should
be taken into consideration when making the
check. Also, if the motor home is equipped with
air bag cylinders, it is important that the cylinders
be inflated to the proper pressure for the load
being carried
in
order to maintain adequate ride
height.
Further diagnosis and alignment checks can be
made at a qualified alignment/front end shop.

BRAKES
On Chevrolet chassis, the. master cylinder is located
under the driver's compartment floor, and is reached
through the left front wheel well.

FRONT SUSPENSION AND ALIGNMENT
The term "front .alignment", refers to the .angular
relationships between the front wheels, the front
suspension attaching parts and ihe ground.
Several factors caa affect front alignment, including
tire inflation pressures, wheel bearing condition, steer-
. ing and suspension components. The following
checks can indicate problems that should be
corrected.
1. Check all tires for proper inflation pressures and
approximately the same tread wear.
2. If the unit is equipped with air suspension com-
ponents, be sure to inspect them according to the
literature included in the Owner's Information
Package. Be sure to keep them inflated to the
recommended pressures.
3. Check for a difference in the ride height between
right and left sides of the vehicle.
43
Inspect the flexible hydraulic brake .hoses which
transmit hydraulic pressure from the steel brake pipe
on the frame to the brake assemblies at the wheels
regularly in accordance with the chassis manufac-
turer's Maintenance Schedule. Check for. road hazard
damage, cracks and chafing of the outer cover, and
for leaks and blisters. A light and mirror may be need-
ed for an .adequate inspection. If any of the above
conditions 'are observed on any brake hose, have it
replaced.
Lining Inspection
. Inspect the brake linings per the .chassis manufac-
turer's Maintenance Schedule and any time that the
wheels are removed (tire rotations, etc.).
DRIVE BELTS·
Proper care and maintenance of drive belts is an
important part of good engine maintenance. Proper
belt tension and the condition of the pulley grooves
are of primary concern.
Since belts and pulleys wear with use, look at all
frictional surface areas for signs of wear. Normal wear
can be recognized as even wear, both on the belt and
the grooves of the pulley. Even with normal wear, belts
