Well the snow is falling in Colorado and once again when I start my truck up in the AM the wipers are not working . After the truck gets warm I can get it to work in the low continous setting. This morning I heard the relay click in the intermittant mode but the wiper did not move. Please help. I need to tell you I am not a mechanic and my mechanical skills are luke warm at best. I want to avoid the mechanic if I can.

 

I would guess a wiper motor park switch which is part of the wiper motor. I had to replace mine, it's pretty basic the hardest part is removing the plastic cowl piece that runs along the bottom of the windscreen behind the wiper arms
