2002 Buick Century Question: Itermediate wipers don't work right. What controls them?
Are you talking about the delay function? if so this is controlled by a timer that is built into the wiper motor, do the regular speeds funtion as they should? - Tbone1980
Agree with Tbone, the motor is most likely the problem. Mechanic can test it but will need it to malfunction to do so! Possible switch, usually motor! - pushrod
AGREE WITH BOTH - globalhelper
