Hide Away Wipers
Help please. I have a 1968 totally restored convertible and my wiper cover will not close. It has worked after the resto until last Sunday when I was out driving. It popped up and will not close. Could it be the limit switch? Any help would be appreciated. 
Thanks, Tom

Check all vacuum connections. Also, use this as trouble shooting guide.http://www.corvettefaq.com/c3/1968Wiper.doc

Check the Limit switch, you are on the right track there. That is just a normally open switch. For a test just jump across the two wires that go to it and start the car. Or if you know how to use a meter check the switch for continuity with the button pushed down. If you see continuity the switch is good…..well at least that is not what is keeping the door from going down. Good luck.

Vacuum problem, not the limit switch. Limit switch only powers the wipers when the plunger closes the switch.
Check the vacuum relay on the right fender skirt before you plunk down the bucks for a solenoid.

There is a wiper limit switch which is mounted horizontally to the wiper motor....and there is a wiper DOOR limit switch which is mounted below the right side wiper. If this switch is not "made", the door will not close. (The system thinks the wipers are still "up"....) There are a number of things which can cause this, but the wiper DOOR limit switch, its adjustment, or feed to that switch are the primary possibilities.
