PRODUCT RECALL CAMPAIGN

PRODUCT SAFETY CAMPAIGN

SUBJECT: 98031 - WINDOW FOGGING

MODELS: 1997-98 CHEVROLET S10 ELECTRIC TRUCK

THE HIGHWAY SAFETY ACT, AS AMENDED, PROVIDES THAT EACH VEHICLE WHICH IS SUBJECT TO A RECALL CAMPAIGN OF THIS TYPE MUST BE ADEQUATELY REPAIRED WITHIN A REASONABLE TIME AFTER THE CUSTOMER HAS TENDERED IT FOR REPAIR. A FAILURE TO REPAIR WITHIN SIXTY (60) DAYS AFTER TENDER OF A VEHICLE IS PRIMA FACIE EVIDENCE OF FAILURE TO REPAIR WITHIN A REASONABLE TIME.

IF THE CONDITION IS NOT ADEQUATELY REPAIRED WITHIN A REASONABLE TIME, THE CUSTOMER MAY BE ENTITLED TO AN IDENTICAL OR REASONABLY EQUIVALENT VEHICLE AT NO CHARGE OR TO A REFUND OF THE PURCHASE PRICE LESS A REASONABLE ALLOWANCE FOR DEPRECIATION.

TO AVOID HAVING TO PROVIDE THESE BURDENSOME REMEDIES, EVERY EFFORT MUST BE MADE TO PROMPTLY SCHEDULE AN APPOINTMENT WITH EACH CUSTOMER AND TO REPAIR THEIR VEHICLE AS SOON AS POSSIBLE. AS YOU WILL SEE IN READING THE ATTACHED COPY OF THE DIVISIONAL LETTER THAT IS BEING SENT TO CUSTOMERS, THE CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE APPROPRIATE CUSTOMER ASSISTANCE CENTER IF THEIR DEALER DOES NOT REMEDY THE CONDITION WITHIN FIVE (5) DAYS OF THE MUTUALLY AGREED UPON SERVICE DATE. IF THE CONDITION IS NOT REMEDIED WITHIN A REASONABLE TIME, THEY ARE INSTRUCTED ON HOW TO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION.

DEFECT INVOLVED

GENERAL MOTORS HAS DECIDED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN 1997-98 CHEVROLET S-10 TRUCKS WITH ELECTRIC DRIVE. RAPID FOGGING OF THE INTERIOR GLASS CAN OCCUR WITHIN TWO MINUTES AFTER THE HEAT IS TURNED ON IF (1) THE OUTSIDE TEMPERATURE IS BETWEEN 35 AND 76 DEGREES FAHRENHEIT AND (2) WATER HAS COLLECTED ON THE HEAT EXCHANGER DURING PREVIOUS OPERATION OF THE AIR CONDITIONING (WATER CAN REMAIN THERE EVEN SEVERAL DAYS AFTER THE AIR CONDITIONING WAS USED). IF RAPID FOGGING WERE TO OCCUR DURING DRIVING, IT COULD OBSTRUCT THE DRIVER'S VISION AND LEAD TO A CRASH WITHOUT PRIOR WARNING.

ADVISE ALL DRIVERS TO FOLLOW THIS PROCEDURE TO HELP AVOID FOGGING DURING DRIVING:

"STOP AND WAIT" PROCEDURE

NEVER DEPRESS THE HEAT SWITCH WHILE YOU ARE DRIVING. WHEN HEAT IS NEEDED, PARK THE VEHICLE IN A SAFE PLACE. DEPRESS THE HEAT SWITCH. IF NO FOGGING OCCURS AFTER THREE MINUTES, YOU MAY BEGIN DRIVING. IF FOGGING OCCURS, USE THE DEFROST MODE UNTIL THE WINDOWS ARE CLEAR FOR SAFE OPERATION OF THE VEHICLE.

TO REMIND DRIVERS OF THE "STOP AND WAIT" PROCEDURE, WE ARE ENCLOSING A CAUTION LABEL FOR INSTALLATION ON YOUR VEHICLE AND A SUPPLEMENTAL INSERT FOR YOUR OWNER'S MANUAL. YOU SHOULD INSTALL THE ENCLOSED CAUTION LABEL ON YOUR VEHICLE ACCORDING TO THE ATTACHED INSTRUCTIONS OR YOUR CHEVROLET DEALER WILL INSTALL IT FOR YOU AT NO CHARGE.

USE OF AN "ANTI-FOGGING" AGENT ON THE INSIDE SURFACES OF THE VEHICLE'S GLASS, ACCORDING TO THE MANUFACTURER'S DIRECTIONS, CAN REDUCE THE SEVERITY OF FOGGING. THE EFFECTIVENESS OF THESE AGENTS IS A FUNCTION OF MANY VARIABLES, SUCH AS TIME SINCE THE LAST APPLICATION, ANY CLEANING OF THE INSIDE GLASS SURFACES DURING VEHICLE WASH, ETC. ALL DRIVERS SHOULD CONTINUE TO FOLLOW THE PROCEDURES DESCRIBED ABOVE EVEN WHEN AN "ANTI-FOGGING" AGENT IS USED.
