Idivayisi kagesi esetshenziswa ukuguqula amandla kagesi ibe amandla kagesi i-Wiper motor ishayelwa injini, futhi ukunyakaza okuzungezayo kwenjini kuguqulwa kube ukunyakaza okuphindaphindayo kwengalo yokusula ngomshini wokuxhuma wenduku, ukuze kubonakale isenzo se-wiper. Ngokuvamile, injini ingaxhunywa ukwenza i-wiper isebenze. Ngokukhetha isivinini esikhulu nesivinini esiphansi, i-current motor ingashintshwa, ukuze ulawule isivinini se-motor bese ulawula isivinini sengalo ye-wiper.
I-wiper yemoto ishayelwa yi-wiper motor, ene-potentiometer yokulawula isivinini semoto yamagiya amaningana.
Ngemuva kwe-wiper motor kukhona igiya elincane lokudluliswa kwegiya elivalwe endlini efanayo, elehlisa ijubane lokuphuma lifinyelele isivinini esidingekayo. Le divayisi yaziwa kakhulu ngokuthi i-wiper drive assembly. I-shaft yokuphuma yomhlangano ixhunywe nedivayisi yemishini yokuphela kwe-wiper, eqaphela ukushintshwa okuphindaphindiwe kwe-wiper ngokusebenzisa i-fork drive kanye nokubuya kwentwasahlobo.
