You may want to check to see if your aux fans are operational. It only comes on at a predetermined temp. One way to check it is to turn on the AC, the two small fans in the front should come on.

Do a search on the forum on your windshield sprayer issue. Some member recently had the same problem and the fix was listed on the forum. I cannot remember which thread but you can type in windshield and see what comes back. Good luck.
