Remove the windshield washer reservoir and give it a good cleaning with a mixture of 1 part bleach and 3 parts water. You may be able to clean it without removing the reservoir by flushing it throughly and the cleaning it while still on the vehicle with the bleach mix. After it is throughly cleaned put a bleach mix in the reservoir and disconnect the hoses from the spray nozzles and run the washer until the hoses are clean. Use a needle to clean out the nozzles, and the connect the hoses and run the washer until the nozzles are clear. Remove the bleach mix and then fill the reservoir with a commercial windshield washer fluid. I recommend Rain X.

the pump motor likely is bad. get a used washer fluid reservoir at a pick n pull yourself or at car-part.com. page with * is lowest cost.

It sounds as if there is a blockage either in the base of the screenwash reservoir or the feed pipe from the reservoir. You could remove the screenwash reservoir tank and clean it out and at the same time check the pipe.

Please remember to rate this solution.

Remove the hose from bottom of tank, steal your wifes hair blow dryer and melt the ice that way. If you can remove the tank easily place it in a sink full of hot water at that will melt it. They make special additives for windshield washers, but regular rubbing alchohol will work. No matter what you use rub some of it on a small area of your car to make sure it will not damage the paint. Hope this helps
