95 s10 4 cyl.

my wipers work sometimes, is it a bad ground? if so where would it be? please help.

If your problem is it sudenly cutting off during rainy days then it is probably the wiper controll circuit board. Alot of older gm's have this problem the new board is about $30 and can be bought anywhere that sells auto parts.
