Sunroof

[CamelotShadow]

The sunroof on my 83 500 SEC won't close.
It opens fine but won't close so I have to crank it shut.

I don't use it but now when it rains water drips in.

Is there a way I can get it to shut all the way?
There must be a slight opening.

What could it be?
The motor opens the roof fine but does nothing when I press it to close?

My guess is the button may not be making contact?
Motor is functional so what should I look into to try to source out the closing problem?

Thanks
