Take out the board and see if there are any cold solder joints on it. If there are, heat 'em up with a soldering iron and resolder the joints.
my room mate who lives in the basement is a studying aircraft electrical engineer. he tested the board for me and all the solder joints are good, but the problem is getting too unsafe and i need to solve this. if the board is good and the gound is good, plus, he tested the switch on the collum, anything else? the only thing that was ever pointed out is those 2 little spring connections from the board that contact that disc which i might assume is my wiper delay. my level of understanding electrical is limited to say the least. but one spring has a ball on the end and the other is only 1/2 a ball.... does my description make any sence? i have tried to take pics but when i zoom in, it's all blurred and of no help even if i posted it. i can't order one from the parts store cause they have no decription of that board, just the expensive complete unit!
