Wipers - How does the spray system operate? Options

[hi4head]

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
