1964 option C14 - WIPER SYSTEM WINDSHIELD ELECTRIC - Need Help

The factory default was for 1-speed wipers without washers through 1965. The RPO C14 2-speed wiper motor also contains the washer pump. All should be present if it is to work. I dont have a picture around but the 2 different wiper motors look different and it needs to be ascertained that you in fact have the 2-speed wiper motor still. It could have been changed anytime in the last 52 years.

There should be a plastic reservoir on the drivers side rad support. The rubber hose should run from there back alongside the wiring harness for the generator & forward lights. The hoses that run to the nozzles run from the wiper motor. The hoses pass under a rubber seal on the top of the firewall, and then couple to metal clips that should screw into existing holes atop the firewall. Those clips are actually the nozzle assemblies and it takes over for the hose, aiming at the windshield through the cowl vent several inches from the windshield. On the drivers side the hose should be around where the trim tag is, while on the passengers side the hose first is routed through the firewall wire loom.

I have a 67 that came with 2-speed wipers with washers standard but at least it is a first generation Chevelle / Beaumont with most things in common with a 64 model.

Take a look at the 2 illustrations from my 67 Chevelle Assembly Manual.

Is the C14 option from the GMVVS sheet or is it on the data tag?

Washer bottle configuration and pump/motor location are where Cam says.

I was searching and found this underhood pic of a 65 Chevelle. Note the hose routing and how it doesn't pass through the rubber seal on the firewall but rather behind it, then refer to the pics that rkycoast posted. The nozzle pics look like the hose is supposed to run behind the seal rather than straight through (see pic #2 above in the previous post). Perhaps that is one of those early model idiosyncrasies that was changed in later years. Anyway, take a look at the picture of the 65 below:

Yes, those pics help a lot (as does the info Cam provided).

Now that I look at the front (previously I assumed - wrongly - that the reservoir would be by the cowl) I do have the reservoir like yours:

(although some bozo ran the coolant overflow line in to its top)

My wiper motor looks like yours (and the one on assembly manual sheet A6), but without the part that appears on the left in this photo with the little hose ends underneath:

So someone, in years past, removed the pump part and just left the wiper motor part (or replaced the whole thing with just a wiper motor).

Mine looks like this:

I can see only 2 wires coming from my wiring harness to the motor - doesn't seem like enough wires to run the motor as well as a pump.

Maybe some day in the future I will try to find an original motor with pump (and nozzles - missing from my car) and figure out how to do it right.

Thanks guys, your information is essential for me to understand what I have and how it should be.

Well, perusal of my new 1964 Acadian Beaumont Shop Manual leads me to conclude that some dastardly person in the past replaced the proper 2-speed-with-washer motor with a single speed, non-washer motor. Phooey. A pox upon that person, wherever he be.

I think I will just live with it. It's not like I will be driving it in the rain, anyway. Sunny days, top down, that's the ticket! (and our rainy season is Summer when it is too hot to be outside w/o A/C, and the sun would bake you to death with the top down - other seasons, different story)
