TO:
ALL CHEVROLET DEALERS
Repeated or prolonged attempts to operate the washer pump under certain conditions (washer bottle dry, washer fluid frozen, etc.), can result in a high
inductive current through the washer switch. This may cause the switch contacts to stick, applying constant current to the pump, which may result in
damage or failure of the pump.
The switch was redesigned in July of 1987, to be more tolerant of high current and reduce potential for sticking. The new switch was incorporated into
all vehicles built after August.
If it is necessary to replace an inoperative washer pump on vehicles built before VIN's JE515660 and JY522263, the switch should also be replaced, if
there is any indication that the washer fluid may have been frozen. The new switch part number is 10094628.
