With lever set at OUTSIDE position, outside air is allowed to enter
and/or pass through heater. With lever set at INSIDE position, air is
recirculated inside passenger compartment.
BLOWER SWITCH
The blower can be operated at different fan speeds to
regulate amount of air forced through vehicle. Fan speed will increase
as switch is turned or moved right.
AIR CONTROL INDICATION SYSTEM
This system consists of indication lights built into
instrument cluster and 4 switches connected to various control levers.
An indication light glows when heater blower is on. Lights also
indicate choice of outlets and whether air source is inside or outside
vehicle. In addition, temperature of air directed from outlets is
indicated for each air outlet by light colors of green (cool air) and
orange (warm air).
ADJUSTMENTS
HEATER (TEMPERATURE) CONTROL VALVE
Place control lever to indicated position. See TEMPERATURE
CONTROL CABLE ADJUSTMENT table. See Fig. 3. Connect cable to heater
control valve and/or air damper lever according to table. Secure cable
sleeve using clips. With engine running, check for coolant leaks and
check operation of heater control valve. If heater control valve does
not operate properly, adjust by moving cable sleeve forward or
backward at retaining clip.

screws. Remove dash panel.
4) Remove blower duct, center duct and defroster ducts. See
Fig. 2. Disconnect heater wiring harness from heater unit. Remove
heater center support brackets. Remove heater unit. Remove heater core
cover plate and joint hose. Remove heater core from heater unit.
Installation
1) To install, reverse removal procedure. Insert heater hoses
fully into pipes, and clamp securely to prevent leaks.
2) When filling radiator with coolant, first open heater
control valve fully and run engine to circulate coolant and discharge
air from inside heater and engine cooling system. Stop engine, and add
coolant.
3) Adjust all control cables. When installing heater hose
grommets, apply sealer. After installing heater control assembly,
ensure each lever operates smoothly.
HEATER CONTROL PANEL
Removal (Montero)
1) Remove heater control knob and heater fan switch knob.
Remove center console. Remove defroster nozzle at temperature control
cable side.
2) Remove lap heater duct and glove box stopper, and push
glove box forward and down. Disconnect inside/outside control cable
from blower assembly.
3) Disconnect control cables from heater unit. Remove heater
control panel mounting screws, and pull out panel slightly. Disconnect
heater fan switch harness connectors. Remove heater control panel.
Remove heater fan switch from heater control panel.
Installation
1) Place air outlet change-over lever at closed position.
With heater side air outlet change-over damper lever in position,
connect inner cable to lever, and secure cable casing using clips.
2) Place heater control lever at OFF position. With heater
control lever in position, connect inner cable to lever, and secure
cable casing using clips.
3) Place inside/outside air change-over lever at INSIDE
position. With heater side inside/outside air change-over damper lever
in position, connect inner cable to lever, and secure cable casing
using clips.
4) Set control lever to each position to check for correct
operation. If lever does not operate correctly, adjust by moving outer
wire at clipped point. Ensure each control lever moves smoothly. If
any noise or stiff movement exists, apply multipurpose grease to all
moving parts.
NOTE: When mounting heater control panel to instrument panel,
tighten upper bolts to instrument panel so they also secure
center panel.
Removal & Installation (Pickup & Ram-50)
Remove cluster panel. Remove all control cables at heater.
Remove heater control panel. To install, reverse removal procedure.
Adjust cables as necessary.

GENERAL INFORMATION
Using Wiring Diagrams
All Models
INTRODUCTION
This CD obtains wiring diagrams and technical service
bulletins, containing wiring diagram changes from the domestic and
import manufacturers. These are checked for accuracy and are all
redrawn into a consistent format for easy use.
In the past, when cars were simpler, diagrams were simpler.
All components were connected by wires and diagrams seldom exceeded 4
pages in length. Today, some wiring diagrams require more than 16
pages. It would be impractical to expect a service technician to trace
a wire from page 1 across every page to page 16.
Removing some of the wiring maze reduces eyestrain and time
wasted searching across several pages. Today the majority of
these
diagrams follow a much improved format, which permits space for
internal switch details.
Wiring diagrams are drawn in a "top-down" format. The
diagrams are drawn with the power source at the top of the diagram and
the ground point at the bottom of the diagram. Components locations
are identified on the wiring diagrams. Any wires that don't connect
directly to a component are identified on the diagram to indicate
where they go.

IDENTIFYING WIRING DIAGRAM ABBREVIATIONS
NOTE: Abbreviations used on these diagrams are normally
self-explanatory. If necessary see ABBREVIATIONS
Page 619 of 1333
WIRING DIAGRAM COMPONENT LOCATIONS
When trying to locate a component in a wiring diagram and you
don't know the specific system where it is located, use this handy
component locator to find the system wiring diagram in which the
component is located. Then, go to that system and locate the component
within the wiring diagram.
For example, if you don't know the specific system in which
the ignition switch is located, look up ignition switch in the wiring
diagram component location tables and go to the appropriate wiring
diagram(s) which contain either full or partial views of the ignition
switch. The full view of the ignition switch is located in Power
Distribution.
The first listing for the component will be the full or most
complete view of the component. Additional listings will be partial
views of the component. Not all components are used on all models.
All components will have a partial view in Ground
Distribution and Power Distribution. Data Link Connectors show
connecting circuits between modules. Alternate names for components
may be listed in wiring diagram component locations tables.

DESCRIPTION & OPERATION
Instrument cluster includes speedometer, fuel gauge and
temperature gauge. Fuel gauge has a built-in voltage limiter to keep
voltage supply to gauges at 7 volts. Some models may also have a
shunt-type ammeter, oil pressure gauge, tachometer, voltmeter and/or
turbo boost pressure gauge. Oil pressure gauge uses full battery
voltage. The tachometer operates by pulse feed.
TROUBLE SHOOTING
FUEL/TEMPERATURE GAUGE NOT WORKING
Check for blown fuse, faulty voltage limiter or faulty relay.
Ensure sending unit connections are clean and tight. Test sending unit
for correct operation. Tighten connections in instrument cluster.
SPEEDOMETER NOT WORKING
Ensure speedometer cable is properly connected and correctly
routed. If speedometer pointer and/or odometer still do not work,
replace speedometer as an assembly.
TACHOMETER NOT WORKING
Tachometer is serviced as an assembly. If wiring harness is
okay, replace tachometer assembly.
WARNING LIGHTS NOT WORKING
Test for defective sending unit, burned out bulb, or broken
printed circuit. Ensure all wire connections are clean and tight.
TESTING
FUEL TANK SENDING UNIT
Resistance Test
Remove fuel tank sending unit from fuel tank. Measure
resistance between appropriate terminals with fuel float in Full and
Empty positions. See Fig. 1. Compare resistance reading to
FUEL TANK SENDING UNIT RESISTANCE SPECIFICATIONS table. If resistance
is not to specifications, replace fuel tank sending unit.

OIL PRESSURE GAUGE
Circuit Test
Disconnect oil pressure gauge wiring connector from sending
unit inside the engine compartment. Connect a 12-volt test light
between harness connector terminal and ground. Turn ignition on, but
DO NOT start engine. If test light comes on and gauge needle moves, go
to GAUGE RESISTANCE TEST. If test light does not come on and gauge
needle does not move, repair wiring to sending unit.
Gauge Resistance Test
Remove instrument cluster from instrument panel. See
INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Check continuity
between oil pressure gauge terminals. See Fig. 4 or Fig. 5. See
OIL PRESSURE GAUGE RESISTANCE SPECIFICATIONS table. If resistance is
not within specification, replace oil pressure gauge.
