Hello

I recently purchased a 1990 500SL hard/soft top. I have been researching here on soft top problems because I can't seem to get the power soft top to function. I can get it to "power lock" into place once I have manually colsed the top, but it won't open or close on its own when pushing the power top button.
I think I should start by finding the error codes for the power top but am uncertain where to start and how to obtain them.

Thank you for any guidance
