I can't find much of anything in my manuals or in searches as to how the wiper spray system actually functions. I know that the tank is supposed to get pressurized from the spare and that pulling on the wiper arm is supposed to allow the spray action to occur.
When I purchased the car it was missing the wiper fluid tank and cap. It did have the connections to the spare tire and the lines leading from the fluid tank. I've purchased a tank and a replacement cap with the short attaching hose.
I think that I've attached things correctly to the tire and have the tire pressure over 35 psi. However, I'm not getting any spray.
My wipers work fine, but no spray when I pull on the lever. Is the lever simply an actuator that opens a valve, or is the something electrical also going on?
Can someone explain how this system is supposed to work?
Thanks,
Chris
Note: Pictures have now been added in a later post that I've made.
i believe it is strictly a mechanical valve... as the hose runs all the way into the dash... up to the column.....
it sucks when it leaks.....
Clogged spray jet?
Pull the hose off one of the spray jets and try again.
If you have pressure there, stick a needle in the jet and try to free up the blockage. Car wax, water deposits, etc, can clog up the jets. Especially if they hadn't been used in a long time.
If they leak your lap gets wet........
You probably have a blockage in the line.....work backwards (from the lever) and blow compressed air thru it to check.......disconect the lines at the squirters too and blow them out
Don't leave it hooked up to the tire if it doesn't spray. That pressure will want to go somewhere, and odds are it will end up leaking all over your floor while you're out of town for the week so you don't find out 'til days later. Ask me know I know.
POORLY
mine uses an electric pump...
Thanks for the input guys. This gives me a couple of ideas on troubleshooting.
But based on some of the comments and other searches that I've done makes me wonder if I should just go ahead and install a small electric pump along with an new lever with the wiper switch or put a small small push-button switch to activate an electric pump.
Again, thanks for the input. Hopefully after I know more about this car I'll be able to provide input to others as well.

And Happy Father's Day to those of you with kids.
Hey how hard is it to get at the hose where it connects to the lever in the steering column? Filled mine with fluid and had it leaking out when turning and all over my foot. Does not squirt out at windows at all. Figure I have a leak at / in the column.

After doing some more checking, I think that I've got a situation similar to Evan.
At first my washer tank cap wasn't working and the tank wouldn't pressurize. I played with it and now get tank pressure. Now I've discerned that there is a leak at the steering column; I can hear the leak and was able to get a finger through the dashboard holes to feel the air and the small amount of fluid that had been in the line.
I guess that I'm glad that I didn't have the tank full and end up with a quart or so of wiper fluid on my floor.
This morning I'm trying to get access to the steering column switch and see if it is just a cracked line.
There's not too many Father's Days when I can simply play with my car. The kids are all grown and moved and my wife's down in FL helping her parents move back in to their hurricane ravaged condo. Most of yesterday was spent working on my truck and the yard -- today I can play (and maybe have a beer or two).

I've torn into the system and have taken some pictures that might help some others with their original systems (if anyone besides me hasn't already switched to an electric pump).
After the knee pad is removed, there is a small opening from which the washer lines and the 'barbs' can sort-of be accessed.
This first picture shows the opening and the two washer lines. The bottom line (fully black) is the line coming from the pressurized washer tank. The line with the orange stripe goes on the top barb and eventually goes to the spray nozzles. I've disconnected one of the electrical connectors for more access.
The second picture shows the feed line removed and shows the barb from the wiper system controller.
I've managed to temporarily get the shortened feed line back on the barb, but is is tough going without removing the mechanism.
