Is the brake light coming on when you pull up the emergency brake handle? No. Pull it up... push it down... several times. Try to get that brake light on.
Yes... brake light on...
Poke your finger into the latch hole (top of windshield, middle). Poke it in out..
A little troubleshooting...
That's all I've got out of the gate. Lots of info about the tops on this forum...
