2003 Buick Lesbare Custom, wipers will not shut off
Our 2003 Buick Le Sabre Custom started having the wipers run by them selves while driving a week or so ago. Yesterday they just started wiping after the car was running. Switch seemed to only wash or mist function but would still keep going with switch off. Headlight, turn signals all work OK. I ended up pulling the fuse for the wipers (#3 under hood fuse block) when wiper reached the down position. I have heard two possibilities, the multi-function switch or the motor. Both expensive. What do think of running a switch to the fuse block and just turning it on when needed? Cheaper than replacements, yes?
