Wiper Switch

[Slugblaster]

My wipers on my 95 Sierra 2500 stopped working. I turn them on by twisting the turn signal and I can hear what I think is the motor humming but no operation of the wipers. I don't know where to begin to fix this problem. Any help is appreciated.

Your problem most likely lies in the wiper control module located and attached to the wiper motor. If you can sodier you can repair it your self by removing the wiper motor and opening the cover on the control circuit board and resodier the ground conections. You could most likely do the sodier repair with motor in place but, I prefere taking it to my bench. You may want to talk to your dealer there is a recal on this control circuit. I choose to repair it my self and not deal with the dealer.
