98' Silverado Wiper Motor Buzzing, Wipers don't work.... Any ideas?

    So on my way to work this morning I tried using my wipers, but all I got was a buzzing/humming sound coming from what sounded like the wiper motor. Any ideas as to what the problem may be? I did a little research and some people said it may be the solder connections are cracked. Or could it be the motor is bad and I should just replace that?

    Thanks,

    Doug

    Id shoot for a wiper motor.. Welcome to one of the most common problems on the GM trucks of our generation. You could try and tap it with a hammer (lightly) if you need it to get you home...

    About ten years ago my wipers quit working on my '96 Suburban. If I rememmber correctly it was a elec. board and not the wiper motor. Appearantly this was a common problem. Sorry but I can't remmember what the board was called. There was a GM bulliten back then.

    We had an identical problem on my(then my mother's) '94 Suburban. The motor would turn if I whacked it with a wrench, but would sometimes freeze right in the middle of a cycle. Replaced the motor about six or seven years ago and haven't had another problem.

    Curious if you've got it fixed yet Doug?

    My GMC is doing the same thing, stopping and buzzing, but sporadically and I want to get it fixed before the fall rains start...

    Also curious how hard it is to get to the wiper motor - I haven't had a chance to look yet.
