rapid oil loss, such as a leaking oil line or oil pressure sensor, and repair or replace as
necessary.
b. Check the oil pressure sensor operation by substituting a known good sensor.
c. Check the oil pressure sensor wire for being shorted to ground. Disconnect the wire
from the oil pressure sensor and with the ignition in the ON position, but not running,
the oil pressure light should not be working. If the light works with the wire discon-
nected, check the sensor wire for being shorted to ground. Check the wire routing to
make sure the wire is not pinched and check for insulation damage. Repair or replace
the wire as necessary and recheck before starting the engine.
d. Remove the oil pan and check for a clogged oil pick-up tube screen.
Parking Brake Warning Light a. Check the brake release mechanism and verify the parking brake has been fully re-
leased.
b. Check the parking brake light switch for looseness or misalignment.
c. Check for a damaged switch or a loose or shorted brake light switch wire, and replace
or repair as necessary.
3. Warning li#ht(s) inoperative with iflnition on,
and engine not started
a. Check for a defective bulb by installing a known good bulb.
b. Check for a defective wire using the appropriate wiring diagram(s).
c. Check for a defective sending unit by removing and then grounding the wire at the
sending unit. If the light comes on with the ignition on when grounding the wire, re-
place the sending unit.
1. Turn siflnais or hazard iiflhts come on, but do not flash
a. Check for a defective flasher unit and replace as necessary.
2. Turn signals or hazard iiflhts do not function on either side
a. Check the fuse and replace, if defective.
b. Check the flasher unit by substituting a known good flasher unit.
c. Check the turn signal electrical system for a defective component, open circuit, short
circuit or poor ground.
3. Turn siflnais or hazard lights only work on one side
a. Check for failed bulbs and replace as necessary.
b. Check for poor grounds in both housings and repair as necessary.
4. One siflnai light does not work
a. Check for a failed bulb and replace as necessary.
b. Check for corrosion in the bulb socket, and clean and repair as necessary.
c. Check for a poor ground at the bulb socket, and clean and repair as necessary.
5. Turn signals flash too slowly
a. Check signal bulb(s) wattage and replace with lower wattage bulb(s). 6. Turn signals flash too fast
a, Check signal bulb(s) wattage and replace with higher wattage bulb(s).
b. Check for installation of the correct flasher unit and replace if incorrect.
7. Four-way hazard flasher indicator iiflhi inoperative
a. Verify that the exterior lights are functioning and, if so, replace indicator bulb.
b. Check the operation of the warning flasher switch and replace if defective.
0. Turn signal indicator ii#ht(s) do not work in either direction
a. Verify that the exterior lights are functioning and, if so, replace indicator bulb(s).
b. Check for a defective flasher unit by substituting a known good unit.
9. One turn signal indicator liflht does not work
a. Check for a defective bulb and replace as necessary.
b. Check for a defective flasher unit by substituting a known good unit.
1. Horn does not operate
a. Check for a defective fuse and replace as necessary.
b. Check for battery voltage and ground at horn electrical connections when pressing the
horn switch. If voltage is present, replace the horn assembly. If voltage or ground is
not present, refer to Chassis Electrical coverage for additional troubleshooting tech-
niques and circuit information.
2. Horn has an unusual tone
a. On single horn systems, replace the horn.
b. On dual horn systems, check the operation of the second horn. Dual horn systems
have a high and low pitched horn. Unplug one horn at a time and recheck operation.
Replace the horn which does not function.
c. Check for debris or condensation build-up in horn and verify the horn positioning. If
the horn has a single opening, adjust the opening downward to allow for adequate
drainage and to prevent debris build-up.
1. Windshield wipers do not operate
a. Check fuse and replace as necessary.
b. Check switch operation and repair or replace as necessary.
c. Check for corroded, loose, disconnected or broken wires and clean or repair as neces-
sary.

3. Windshield wiper motor operates, but one or both wipers fail to move
a. Windshield wiper motor linkage loose or disconnected. Repair or replace linkage as
necessary.
b. Windshield wiper arms loose on wiper pivots. Secure wiper arm to pivot or replace
both the wiper arm and pivot assembly.
4. Windshield wipers will not park
a. Check the wiper switch operation and verify that the switch properly interrupts the
power supplied to the wiper motor.
b. If the wiper switch is functioning properly, the wiper motor parking circuit has failed.
Replace the wiper motor assembly. Operate the wiper motor at least one time before
installing the arms and blades to ensure correct positioning, then recheck using the
highest wiper speed on a wet windshield to make sure the arms and blades do not
contact the windshield trim.
1. Speedometer does not work to minimize sharp bends or kinks.
If the sheathing has been
