2005 tahoe. When its warm out I click the switch and the wiper works. When its cold out I click the switch and it doesnt work. I drive it into my garage and let it sit in a 60 degree atmosphere for 20min and when I click the switch it works, back it out of the grage to where its 20 degrees and click the switch and it doesnt work. I took the tail gate panels off and ttried it and same thing. I could understand if water was freezing but its totaly dry. I wonder if there is some stupid mercury switch which prevents it from working in the cold, if so I never heard of that before.
