Where there should be a pic in your post is a box with a red "X" in it. Right click, choose "Properties" get a URL. Cut and paste that, got "Page Cannot be Displayed" twice. Therefore I do not know what the nozzle on your car looks like.

But - on the chance that you have a 245 similar to the ones I have owned, here's what I did:

Both the rear nozzle and the two on the hood have a little ball with a hole in it that is the nozzle. The ball can be moved about by putting a thin sewing needle in the hole and moving it slowly. I found that a little movement of that ball moves the spray hit spot a large distance.

I think the hit spot of the rear window is half way across and a few inches below the apex of the wiper sweep. Trial and error for what works best.

Good Luck,

Bob
