My slk 2000 roof has just stopped working. It wont go down at al

You need to pump the hydraulics manually, to do this first sit on boot and press boot button for a few seconds without allowing the boot to open. Partially allow boot to open, manually push boot all the way open and closed a dozen or so times to manually pump hydraulics. I had same prob, this sounds extreme but does work and wont cost you a penny.

The micro switches for the hard top latches are bad and not sending a closed signal to the control module. When they stop working the control module doesn't know the top is closed so it doesn't raise the windows. Those micro switches are known to go bad. I have changed quite a few of them before.

your can check is it something stuck in the lock, first operate your roof either way, if you are going to open the roof as a first action boot lid will open to backward, let boot lid fully open and stop operating the roof, ignition off and have a look if something stuck you can see, if you are going to close the roof let close the roof and before close the boot lid stop operating roof switch, otherwise faulty boot lid lock, if faulty lock but you can try by mettle key blade which is in your electronic key, first take out mettle key from electronic key then insert mettle key in to the key hole in boot lid turn fully left and open boot if not work turn fully left and push it in, is this information helped you?

If the top is half way down that means that the trunk is open and should be touching the trunk switch to continue the process. The switch must be bad and it is inside the rear right fender close the the stop light

It could be an in-line fuse, which you would need to search for, out with the fuse box. Follow the wiring as it enters the driver area, then along to towards the motor for the roof.

This symptom almost always points to a mechanical issue, not an electrical one. The SLK hardtop is notorious for needing to be lubricated every couple of years. Here is a link with directions and photos:

Sticking joints are the most common culprit to intermittent raising and lowering problems. Once those have been lubricated and that has been checked off the list, then consider looking into electrical issues.

The moisture from the rain may be helping to lubricate these joints and that might be why it works fine in the rain...
