The problem
THE SWITCH USED MAY NOT BE COMPATIBLE WITH THE WIPER MOTOR. THIS SYSTEM, ALTHOUGH FUNCTIONAL, IS NOT IN COMPLIANCE WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 104, "WINDSHIELD WIPING AND WASHING SYSTEM". THE WINDSHIELD WIPER SPEED MAY REMAIN NEARLY CONSTANT WHETHER IN HIGH OR LOW SPEED MODE. THE STANDARD REQUIRES THAT THE DIFFERENCE BETWEEN HIGH AND LOW SPEED MUST BE AT LEAST 15 CYCLES PER MINUTE TO ACCOMODATE A VARIETY OF RAIN, SNOW, OR WHEEL SPRAY CONDITIONS.
What owners should do
WIPER SWITCHES WILL BE REPLACED IF NECESSARY, WITHOUT CHARGE.
