Hi.
I’ve searched a bunch of forums and not really found a working solution for my problem. This forum has more about it than any of the others I have found, so here we go...
The car is a 1990 model 300SL that had the hardtop on over the winter. When it was time to remove the hardtop it wouldn’t release all the locks, so we removed it manualy with the tool that came with the car.
So far so good, but when I try to close the soft top, the windows and roll bar went down, and that’s it... I then try to pull the putton backwards a little, and the windows and roll bar goes a bit up and down again before everything stops.
I then notice that the LEDs in the roll bar button are flashing and so is the roof button then i press it forwards. Didn’t get it to work, so I put the top on manualy at that time.
When starting it later I notice that the roof button is lit all the time , and there are some noices comming from the rear. Kind of the sound of the vacuum pump for the locking system, only it takes way too long for it to stop. When I manualy remove the top and all locks are on, the red light in the button goes away and the flashing in the roll bar button comes back.
I’ve disconnected the battery for a while to reset everything, and tried all the reset tips I have found with windows and roll bar. Roof still not working.
Do you think the ECU is defective, or what could it be? Any tips?
