    Sometimes when I turn the windshield wipers on they don't #### off for about 30 seconds to a minute. What do you guys think this is?

    It is helpful to tell us what model of truck it is and year.

    Some had the delay/mist built into switch, a new switch could fix it?

    Is the switch in the middle? You know that its a 3 position switch right? open the dash and turn them on, then unplug the switch to see if they stop. if its not the switch, the next is the ECC, and or the wiper motor itself. The motor sends a signal to the ECC to tell it the arms are in home position. If the ECC doesnt hear this, it will keep going.

    I haven't checked it out yet but the wipers only do this in the rain. If I flick them on and off they stop right away (when driving in fog )
