wiper operation ????
Hi, My wipers only work when the wiper switch is depressed for the washers. I replaced switch, wiper overide switch, and vaccum overide switch. No change with the wipers after the items were replaced. What could I be overlooking?

Since the dark blue wire on your switch is the washer mode of the wiper system. When you press the wiper switch you are grounding out the wiper washer mode.
I would start with this:
Make sure the center dash cluster is grounded at the back of the gauges.
If the dash center bezel is broken at the tiny area, I would run a jumper ground from the switch to the back of the gauge cluster.
Make sure the wiper motor has the ground on it from the terminal on the outside to the blower motor circuit.
Verify the ground on the wiper relay (in the console with a black wire with a white stripe) is a good ground.
Look at the picture on the link I just gave you! Try looking at this stuff and then email me at Willcoxcustomerservice@Willcoxcorvette.c om.
We can help you fix this and it’s not hard. I will be out of town the next couple of days but will check the cust. Serv. Emails as often as I can.

Have you tried unplugging the connection and turning it around and plugging it back in. Yours sounds like it was acting just like mine. I plugged it in backwards accidentally after working behind the gauge cluster and didn't realize it. Try flipping the connection around before you buy anything else! 
If that doesn't change anything, at least it was free.

Look at the picture in post number six, the connector is in backwards, the skinny tab needs to be on the other side.

Flip the connector upside down. You've installed it the wrong way. [not like anyone else has ever done that]
