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.
If a fuse goes out, replace the fuseas soon as you can.
