1990 500SL top problem

Hello I just recently purchased a 1990 500SL and I’m having a problem with releasing hardtop. I just want to see condition of soft top prior to drop top weather. Today is cold here in New England not sure if this is contributing to problem? So here’s whats going on. I start the car, lower the windows completely, open doors completely, put on emergency brake then I pull back on red button. The red light flashes but nothing happens. When I push button forward I here thumps on back of top but that’s it.
Please help!! Thank you all.

Do not switch on engine. Just turn the key to max power on without engine start.

The flashes indicate a diagnostic code is set in the controller. Read, erase, and re-read the code as explained here: https://www.benzworld.org/forums/r12...ml#post1925941
