Ok guys and gals. I started my 01 the other day at about -15 deg. C. no wipers. Later in the day with the sun shinning the temp. went up to about -5 deg. C. The wipers worked. A couple days later the same issue when my wife moved the truck for snow removal. Again this morning when I went to pull a little GMC out of the snow. I am hoping they work later today as we are snowed in.

Anyone have this issue? What was the problem?

BB.
