When the wipers are turned on in the low speed, they switch to interval mode when the turn signal switch is activated. When the turn signal switch is in the off position, the wipers will remain on interval. To get the wipers back into the low setting, you have to jiggle the turn signal switch to get them to function properly. Sometimes this takes several attempts. All of these trucks in my employer’s ownership have the same issue with some being worse than others.
