Temporarily sealing the vent window

[twosocks90]

My passenger side vent window on my 83 K10 Suburban is so noisy it's driving my crazy. Last year my son broke the hinge pin off the bottom so now it doesn't seal right (it didn't seal all that well before he broke it anyway!) and I don't have time to fix it right now.

I want to silicon the window shut until I have time to fix it. Is this a bad idea? I plan to replace the weatherstrip when I do eventually fix it. I put electric tape on it which helped but it's coming off now. I just need a temporary fix so I can hear the radio again.
