I had this problem with my Villager and continue to have it with my Quest. The Villager went back to the dealer who told me that there were no problems that they could find but it was a common problem with the Quest and Villager. When I need to use the fluid I press and release the switch until the pump kicks on and the fluid sprays. It's a pain but it always comes on after 30 secs. of working the switch. There is a really good Nissan mechanic on allexperts.com who answers 5 questions a day. Sometimes you may have to wait until midnight to get a question in. I also had this same problem with my 97 Quest. It turned out to be a combination of two issues. #1: Crud in the lines, had to use compressed air and a little bit of patience to blow out and rinse the lines a couple of times. # 2 the switch on the steering column as you already know is intermittent. Since I have other issues with the van that are higher on the priority list I've learned where the "sweet spot" is on the switch to get it to work. I simply press in on the switch ( like your supposed to) then gently twist back and forth as if your changing wiper speed until the washer pump energizes. hope this helps.
When the windshield wiper on a 2000 Ford Ranger comes on by itself this can signal a damaged windshield wiper switch. Changing these switches out often corrects this problem.
It is probably comming from the windshield. Have someone run water on the windshield and check it inside with a flashlight.
Either your windshield wasn't installed properly, or the window seal is bad. Getting that problem fixed will be much more effective than using sealant.
Have the windshield removed and retapped.
Rule of thumb, if you can feel the scratch with your fingernail, it ain't coming out, replace the windshield.
According to a quick Google search, there has been a recall on 200SX for this exact problem. Perhaps a dealership near you will be able to take care of the problem.
Water may not be coming through the portafilter due to a clog or blockage in the filter basket, a faulty seal, or a problem with the espresso machine's pump.
You probably have a bad heater core. Find where it is coming from. You probably have debris stopping up the drain below the windshield.
I'm not sure, but I've had this problem before. Check the top of the windshield, and for rust holes in the roof for leakage. I had the same problem with my 1998 LeSabre last month, and it was indeed coming from the windshield.
Leak in exhaust system perhaps exhaust manifold being sucked in through air intake (grid at lower end of windshield)
It doesn't, it is made of glass and plastic film to it from coming apart.
Other postings on the web indicate it is coming from a leak in the upper drivers side of the windshield. Having the same problem on my 2001.
