Lately when I flip my turn signal on the windshield wipers come on. They don't stay on just usually go across once or twice. My truck is a 93 s-10, I was wondering if the whole switch needed to be replaced or if one of you had another idea of what it may be. Thanks,
Dennis

It's the switch, but try getting some electrical contact cleaner and just spray it in there before you try changing the switch.

Give it time and if you have to use the whole bottle of cleaner
