Hi, I am facing a problem with my 97 ES300, windshield sprayer is not working. Whipers are working fine when i try to start spray but spray does not happen. I am not sure where to look for fix. If someone can share some info with pictures it would be great. Tank with windshield sprayer is full and it was working fine until few months back. I always use right grade replacement liquid, never play around with water or other stuff as a sprayer.

1. Is whiper moter and sprayer moter together like a single unit or two different units?
2. Where is sprayer motor located in car and any details about replacement steps along with pictures would be greatly appreciated.

I am a DIY person but have not worked much with cars yet. Mostly other stuff at home.

Thanks
