FUSES & CIRCUIT BREAKERS
FUSE PANEL LOCATION
The electrical system is protected against shorts by fuses
that are designed to fail, to prevent damage to the wire harness. The
fuse block is located under the instrument panel on the driver's side.
If a fuse is blown, locate the cause before replacing the fuse. Spare
fuses are contained in the fuse block.

BLOWER MOTOR TEST
1) Turn ignition on. Check fuses. If fuses are bad, check
wiring harness for short circuits. If fuses are okay, check voltage
between heater relay and ground circuit. If voltage does not exist at
heater relay, check for broken wire between fuse block and heater
relay.
2) If voltage exists at heater relay, check relay, and
replace if necessary. See BLOWER MOTOR RELAY TEST under TESTING. If
relay is okay, disconnect blower motor connector. Set heater switch to
either LO, MED or HI setting.
3) Check voltage between harness side of connector and
vehicle ground. Battery voltage should be present. If battery voltage
is present, go to next step. If battery voltage is not present, check
continuity between resistor terminals. See BLOWER MOTOR RESISTOR TEST
under TESTING. If continuity is not present, replace resistor.

2.6L Engine ........................................... 45
2.6L Optional ......................................... 45
3.0L V6 ........................................... (1) 24
3.5L V6 ........................................... ( 1) 24
( 1) - Check hood clearance on 1986 and newer models.

CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
The SRS has no user-servicable parts. Always have servicing
done by an authorized dealer.
When performing maintenance on air bag equipped vehicles
always observe proper safety precautions.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation
ANTI-LOCK BRAKE SYSTEM (ABS)
CAUTION: Never mix different diameter tires. On loose or uneven
surfaces, the ABS system may require longer stopping
distances than conventional brake systems. Exercise caution
when removing mud or snow from the wheels so as not to
damage the ABS wiring or speed sensors.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
appropriate COMPUTER RELEARN PROCEDURES article in the
GENERAL INFORMATION section below.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.

federal law. Warranty period is 5 years or 50,000 miles, whichever
occurs first. Covers remedy of non-conformity if vehicle fails to pass
an EPA approved emissions test during the first 24 months or 24,000
miles of this warranty. During the remainder of the warranty period,
covers remedy of non-conformity resulting from failure of certain
emission-related components. See copy of warranty for specific
components covered.
EMISSION SYSTEM WARRANTY (CALIFORNIA)
Warrants that the vehicle was designed, built and equipped to
conform at the time of sale with all applicable U.S. and California
emission standards, and that the emission control system is free from
defects in materials or workmanship which would cause the vehicle not
to meet these standards for 5 years or 50,000 miles, whichever occurs
first. On 1990 and later models, warranty coverage is 3 years or 50,
000 miles, whichever occurs first, with certain emission-related
components covered for 7 years or 70,000 miles, whichever occurs
first. See copy of warranty for specific components covered.

FUSE PANEL LOCATION
The electrical system is protected against shorts by fuses
that are designed to fail, to prevent damage to the wire harness. The
fuse block is located under the instrument panel on the driver's side.

WARNING: Avoid breathing R-134a refrigerant and PAG lubricant vapors,
exposure may irritate eyes, nose and throat. To remove
R-134a from system use R-134a recycling equipment that meets
SAE J2210 specifications. If accidental system discharge
occurs, ventilate work area before resuming service.
ANTI-LOCK BRAKE SYSTEM
The anti-lock brake system contains electronic equipment that
can be susceptible to interference caused by improperly installed or
high output radio transmitting equipment. Since this interference
could cause the possible loss of the anti-lock braking capability,
such equipment should be installed by qualified professionals.
On models equipped with anti-lock brake systems, ALWAYS
observe the following cautions:
* DO NOT attempt to bleed hydraulic system without first
referring to the appropriate ANTI-LOCK BRAKE SYSTEM article
in the BRAKES Section.
* DO NOT mix tire sizes. As long as tires remain close to the
original diameter, increasing the width is acceptable.
Rolling diameter must be identical for all 4 tires. Some
manufacturers recommend tires of the same brand, style and
type. Failure to follow this precaution may cause inaccurate
wheel speed readings.
* Use ONLY recommended brake fluids. DO NOT use silicone brake
fluids in an ABS-equipped vehicle.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure. See
appropriate COMPUTER RELEARN PROCEDURES article in the
GENERAL INFORMATION section below.
BRAKE FLUID
For vehicles equipped with a traction control system, idle
engine while pouring brake fluid into reservoir.
CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
ELECTROSTATIC DISCHARGE SENSITIVE (ESD) PARTS
WARNING: Many solid state electrical components can be damaged by
static electricity (ESD). Some will display a warning label,
but many will not. Discharge personal static electricity by
