I too have this same issue and need to take the time to figure out what's going on with it. Ugh.

I had this same problem in college. I pulled the line running to the rear to clean it but then I had an epiphany...I routed the line through the firewall and to the ashtray, cleaned out the reservoir and filled it up with vodka. The alcohol acted as a great de-icing agent for the front while providing wet bar service to the cabin. It was so "James Bond".
That is a common mod raging alchies do to their vehicles. Not saying that is/was you as I remember being in college. I was just shown this mod when I was in high school by an employee at my best friend's father's company. Since then I have come across 2 other complete drunks that have done this. My point, if there is one, is that if I am aware of this I am sure the police are too. Not that it is illegal just pointing out that I don't think it is all that sneaky of a way to hide the booze. And if you ever were pulled over for DWI it would be used in evidence against you.
how do you spray the rear? i've been trying to figure that one out.I'm not getting any fluid to the back, but the wiper isn't moving when I try to spray either. The wiper works on the other settings. Should the wiper be moving when I try to spray?
You roll the knob on the washer lever , look closely and it says rear on it.how do you spray the rear? i've been trying to figure that one out.
i just realized this was the 100 series thread. you wouldn't by chance know how to do it on a 70 series, would you?You roll the knob on the washer lever , look closely and it says rear on it.
I've never had the honor of driving a 70.....or anything other than a 100 for that matter...Great SHAMEEEEi just realized this was the 100 series thread. you wouldn't by chance know how to do it on a 70 series, would you?![]()
filled it yesterday, just trying to figure out how to spray it. maybe it's clogged, we'll see. thanks@wpwilder There is a separate reservoir for the rear wiper in the back of the vehicle. Probably empty.
holy moly it worked. thanks!The button on the dash has three positions. Off, On and then push further (spring loaded) and the washer comes on.
Way late in answering, but...to resurrect an old thread...how do you get the sprayer piece to come off? I just picked up a 2000 100 series yesterday, and the sprayer doesnt work for the back window. Have juice on the front ones, so I know I have washer fluid.
Good to know. Do you know how I get a new one? I don’t see a part number and I sure am not going to put that one back in.It's a level gauge. When you're filling the reservoir it floats up and hits the screen to tell you you're about pour your washer fluid all over the battery.
And if you do use real washer fluid, it'll be less likely to grow black scuzz (that's a word,right?) in the lines and tank!
You might have to clean out your tank. Good luck.
