    Default 94 Suburban wipers only work when it's cold outside

    I have had this truck for 12 years and living in the desert, wipers have not been much of an issue. Well today they were. When it is cold outside, the wipers come right on. If it's warm out I can hear the motor moan like it wants to go, but I have to manually give the wipers a tug to get started. They will also just stop in the middle of the windshield and I have to give them another tug. I have replaced the wiper motor but nothing changed. Ideas anyone?

    Thanks.

    Will try that. When I swapped out motors, I put my old wiper board in because the donor one was cracked.... It appears I replaced my own bad part!
