Before I extract my window - calling on all smart people

First check the weep holes in the window frame to make sure they are clear of debris.

Second. I have had 2 leaks in windows and all I did was put clear silicone around the top. Stopped the leaks. Can't see it AND I didn't have to take any windows out. KISS theory.

Thanks for the response. It is not the weep holes they are free and clear. It is not the top of the window as I have been able to isolate to the seal area of the glass with very careful and light water spray targeting just this area.
