Headlamp Wiring
An electrical overload may causethe lamps to go on and off, or insome cases to remain off. Have theheadlamp wiring checked right awayif the lamps go on and off orremain off.
Windshield Wipers
If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop until the motor coolsand will then restart.
Although the circuit is protectedfrom electrical overload, overloaddue to heavy snow or ice maycause wiper linkage damage.Always clear ice and heavy snowfrom the windshield before using thewindshield wipers.
If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.
Fuses
The wiring circuits in the vehicle areprotected from short circuits byfuses. This greatly reduces thechance of fires caused by electricalproblems.
Look at the silver-colored bandinside the fuse. If the band is brokenor melted, replace the fuse. Be sureyou replace a bad fuse with a newone of the identical size and rating.
Fuses of the same amperage canbe temporarily borrowed fromanother fuse location, if a fuse goesout. Replace the fuse as soon asyou can.

problems with bearing life, brake
cooling, speedometer or
odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
Whenever a wheel, wheel bolt,or wheel nut is replaced on a dualwheel setup, check the wheel nuttorque after 160,1 600, and10 000 km (100,1,000, and6,000 mi) of driving. For propertorque, see“Wheel Nut Torque”underCapacities andSpecifications0468.
