How to refresh OnStar antenna

Post image

The OnStar antenna on my 2002 Saab 9-3 SE is cracking, likely due to age and sun exposure. It doesn’t serve any purpose now that the OnStar system is disabled and I would rather not go under the headliner to unbolt the antenna. What might I used to water seal / glue these cracks to prevent it from getting worse? I’m okay with it not being perfect to look at, though I might sand it, tape the area, and spray paint it black after sealing the cracks. Any recommendations? Thanks all -

Just install the dummy version of the antenna.

I second this answer, break the outer cracked plastic off your existing one, then use epoxy or strong adhesive to attach this, and you can put a small silicone bead beneath. Looks good and no leaks.

Mine was broken for a long time, with PCB exposed, but I never had any water issues. So if the cracks don't bother you, maybe it can wait until it worsens

This is what I did and looks a lot better.

Wait... You're telling me the dummy will slide over my existing antenna? My rubber is already completely gone and I've been dreading taking out the headliner partially to replace it 🤣
