Anyone ever have a Speed Sensor Problem?

[Steve47]

Had the 97 Astro at the mechanic 4x's now for the same problem. The speed sensor comes loose after driving. The last time around I climbed under there and wrapped electrical tape around it to stop the plug from moving around. Anyone else experience this? Any solutions?

I read somewhere here about wiper problems, (cutting on and off and sometimes not working at all) ,,, Someone posted something about drilling the motor case and attaching a ground wire? In case I read that wrong, how can I correct this problem? I also think mentioned was the ground on a circuit board and it cracks?

Update: Found these boards online, Can you tell me which one I should use for the 97 astro Van.
