Air Leaking at seam on 3 year old double hung windows

I am hope you all can help a desperate guy and his cold family.

We have lived in our home for about 3 years and the double hung windows, vinyl, leak air where the two sliding window panes come together and along the side channels.

Last year i used clear, removable caulk and sealed the windows.

This year i tried to use adheasive weatherstripping along the bottom where the bottom window hits the window sill and into the channels on either side going up about 2 inches inside the channel thinking the leaks were coming from there. no luck. still can feel a lot of air coming from the entire seam where the windows touch in the middle when closed.

I attached 3 pics. one is the overall view of one of the windows (FYI not all of them have this issue but 5 or 6 do). The nerf dart is the seam m referring to. The other two are showing closer pics of the seam and the channel.

Let me know what i might try and do or if you need more info if im not being clear.

Thanks all in advance. my toes are cold and could use your help.

Convection?

Are you sure it's the air coming into the home? I only ask because if the glass itself is inefficient, this can cause a draft. The warm air in our home touches the cold window, cools, and falls. Then more warm air flows/is pushed to that space, cools, falls, etc. This can cause a draft from the window in your house even if the seams are fine. There's some info about that at **************** and a few other links on that page.

Otherwise, if it is air infiltrating, you may need to replace the material between your frame and window panes with something less conductive and less sensitive to fluctuations in temperature. Hope this helps a little!
