My roof on my mercedes slk goes up ok but the windows stay down and the swich flashes

I have a CLK 2001 and my rear window buttons just work normally when the roof is down. I can even raise a rear window without raising the front one.

Depending on the year..

It's the switches in the front of the roof and the passenger side A pillar 69/SW1, 69/SW2 and 69/SW3.

the most common problem with those retractable hard tops are leaking hydraulic cylinders. check the insides of your trunk where the top down cylinders are located if there's a leak,and also check the level of the hydraulic fluid situated near the right brake lights.
in your slk manual, there are instructions on how to manually close the roof when the hydraulics fail.

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.

Sounds like maybe some pin switches for interlocks have gone bad. Open your trunk and look for the rubber booted switches and try holding them or shorting them, if you make the top move it shows you which ones are bad.

Get a can of WD 40 spray lubricant at any auto parts store and carefully lubricate all of the moving parts of the roof system. This will likely solve your problem.

This symptom almost always points to a lubrication issue. The SLK hardtop is notorious for needing to belubricated every couple of years. Here is a link with directions andphotos:
