Care of  Safety  Belts 
Keep belts clean and dry. 
A CAUTION: 
Do not  bleach  or  dye  safety  belts.  If  you do, it may  severely 
weaken  them.  In  a  crash  they  might  not  be  able  to  provide 
adequate  protection.  Clean  safety  belts  only  with  mild  soap  and\
 
lukewarm  water. 
Glass 
Glass  should  be cleaned  often. GM  Glass  Cleaner (GM Part No. 1050427) 
or  a liquid household  glass  cleaner will remove  normal tobacco  smoke  and 
dust  films. 
Don’t  use abrasive  cleaners 
on glass,  because  they  may  cause  scratches. 
Avoid  placing  decals on the  inside  rear  window, since they may have to  be 
scraped  off later.  If abrasive  cleaners  are  used on the inside 
of the rear 
window,  an electric  defogger  element  may be damaged.  Any temporary 
license  should not be attached  across the defogger  grid. 
Cleaning  the  Outside of the Windshield  and 
Wiper  Blades 
If  the  windshield  is  not clear  after  using the windshield  washer,  or if the 
wiper blade  chatters when running,  wax or other  material  may  be on the 
blade  or windshield. 
Clean  the  outside  of the windshield  with GM Windshield Cleaner,  Bon-Ami 
Powder@  (GM 
Part No. 105001 1). The  windshield is clean if beads  do not 
form  when 
you rinse it with water. 
Clean 
the blade  by wiping vigorously  with a cloth soaked  in full strength 
windshield  washer solvent.  Then  rinse  the blade  with water. 
Wiper blades  should be  checked 
on a  regular basis and  replaced when worn. 
Weatherstrips 
Silicone  grease on weatherstrips  will make  them last longer, seal better, and 
not stick  or squeak.  Apply silicone  grease  with a  clean  cloth at least every 
six months.  During very cold,  damp  weather  more  frequent  application  may 
be  required.  (See  “Recommended  Fluids  and  Lubricants”  in the  Index.)

Fuses and Circuit Breakers 
The wiring  circuits in your  vehicle are protected  from short  circuits  by a 
combination  of fuses,  circuit  breakers,  and fusible  thermal  links 
in the 
wiring  itself.  This  greatly  reduces 
the chance of fires  caused by electrical 
problems.  See “Fuses  and Circuit  Breakers’’ 
in the Index  for more 
information. 
Headlamps 
The headlamp  wiring is protected by a  circuit breaker in the lamp  switch. 
An  electrical  overload  will cause 
the lamps to flicker  on and off, or in some 
cases  to  remain 
off. If this  happens,  have  your  headlamp  wiring checked 
right  away. 
Windshield  Wipers 
The  windshield  wiper motor  is protected  by a clrculc DreaKer  ana a ruse. 11 
the motor  overheats due to heavy  snow, etc., the wiper  will stop  until the 
motor  cools.  Although  the  circuit  is protected  from electrical  overload, 
overload  due to heavy  snow,  etc., may  cause  wiper  linkage  damage.  Always 
clear  ice  and heavy  snow  from  the the windshield  before  using  the 
windshield  wipers. If the  overload 
is caused  by some  electrical  problem and 
not snow,  etc., be sure 
to get it fixed. 
Power  Windows and Other  Power  Options 
Circuit  breakers in the  fuse  panel  protect the power windows  and  other 
power  accessories.  When  the current  load is too  heavy, the  circuit breaker 
opens  and  closes.  This  protects  the circuit 
until the current  load returns to 
normal or the  problem  is  fixed. 
Trailer  Wiring  Harness 
The standard  seven-wire  trailer  wiring  harness is protected  by an in-line 
fuse  in the  battery  feed wire.  This  fuse  is near the  junction  block. See 
“Trailer Wiring Harness”  in the  Index  for  more  information.
