Wiper Motor

I need some help with my windshield wiper motor on my 67 RS. I don't believe the wiper motor was ever hooked up correctly when I got the car. Now that winter is here and the occasional shower is starting to come to SoCal, I'd like to get this figured out so I can stay safe.

I'm not sure if this motor is the original one or not. From what I can tell, the tube from the washer fluid goes into the bottom of the cylindrical washer motor, but there is no tube hooked up to the output at the bottom of the washer motor. On top of the washer motor, there is a dark blue wire and a yellow wire. On the wiper motor, there are three terminals on top (two together and one not). As shown in the blurry picture from when the engine was just removed, the two-prong connector (with two yellow wires on one terminal and a light blue wire on the other terminal) and the singular black wire are hooked up. There is nothing on the two terminals facing forward and there is nothing hooked up to the plastic connectors on the left.

Can someone help me out? I searched around for a long time and wasn't able to find a picture of how it should look.

Currently, I can turn on the wipers and they work only if the button is pushed so that the washer motor is working too. Once I release the button, the wipers finish their cycle and park at the correct position (what I assume to be the correct position, because I don't have the wipers actually installed - just watching the linkage during operation).

Here is the picture:



Thanks!

Re: Wiper Motor

Jeff, here's a close up of mine.

Pull the plastic cover off first, then hook up the wires and observe the operation. If it all works, you may still have to replace the squirter diaphragm to get it to squirt. Good luck!

Re: Wiper Motor

I don't have that connector with the single yellow and single blue one on the front. I wonder where that went? Thanks for the picture! How about the plastic hookup on the "left" side of the motor. Are there tubes coming off of yours? If so, where from and where to? Also, how about the in and out of the little washer motor cylinder? Or perhaps the little cylinder is a replacement washer motor and that's why there are no wires or tubes hooked up to the main one. Because the same wires are hooked up to the little cylinder on mine (single yellow and dark blue - separate spades). I can take better pictures tomorrow if that will help...

Thanks!

Re: Wiper Motor

Jeff, somebody hacked yours to add that cylindrical pump. (which in my opinion may work better than the original- if it works!) Looks like you have the wires, just not the connector. Put spade lugs on them.

There are three spigots for the hoses on the white plastic part. The large spigot connects to the reservoir. The other two go out to the windshield nozzles. Often, this part needs a rebuild also and you can get a rebuild kit from AutoZone which may or may not contain the pump diaphragm. Mine did not so I had to buy that separately from a corvette parts vendor online.

Your switch may also be bad, as Shop Monkey suggests. The two front wires are related to the washer pump which operates when you push in on the switch(iirc). I think you should be able to run the wipers independently so check to see if you have good connections at those top connectors for starters. Also try the wipers with that cylindrical pump disconnected.
