The spacer usually contains desiccant that is highly absorptive and can absorb excess moisture.

You'll need to buy glass points which is a metallic triangle that keeps the glass in the right place.
With the window sash out of the way, carefully pull it off of the wood molding with a straight pry bar. It is possible to scrape old glazing putty off with a utility blade or chisel. Then, use the heat gun to warm up any putty that isn't able to be removed. This will make it easier to peel off.
When the frame is out of the molding and the frame is firmly pressed, gently press the new glass into its new location. Then, using the help of a putty knife or glazier's point, fill in the gaps around it and smooth them out. After the putty dries paint it in a manner that matches the rest of the frame.
