TROUBLE SHOOTING

BLOWER MOTOR
If blower motor will only run at high speed, check blower
motor resistor. See BLOWER MOTOR RESISTOR under TESTING.
INSUFFICIENT HEAT
Obstructed floor outlets or heater hoses. Bound or improperly
adjusted dampers. Improperly adjusted control cable. Plugged heater
core.
NO VENTILATION
Improper damper adjustment. Incorrect mode selector cable
installation. Improper duct connection, or duct damage.
TESTING
* PLEASE READ THIS FIRST *
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG RESTRAINT
SYSTEM article.
BLOWER SWITCH
Disconnect switch, and check continuity between indicated
terminals using ohmmeter. See BLOWER SWITCH CONTINUITY table. See

BLOWER MOTOR

Disconnect blower motor connector. Connect battery directly
to blower motor terminals. Ensure blower motor operates smoothly.
Reverse polarity, and ensure blower motor operates smoothly in reverse
direction. Replace blower motor if it does not function as specified.
BLOWER MOTOR RELAY
1) Remove blower motor relay from junction block, located
under hood on driver's side fenderwell. Using ohmmeter, check
continuity between terminals No. 1 and 3. See Fig. 7. Continuity
should not be present.
2) Check continuity between terminals No. 2 and 4. Ensure
continuity is present. Connect 12-volt battery to terminals No. 2 and
4. See Fig. 7. Ensure continuity exists between terminals No. 1 and 3
with voltage applied. If continuity is not as specified, replace
relay.

HOW TO USE SYSTEM WIRING DIAGRAMS
1998 Mitsubishi Montero
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.
