I have a very strange problem in my 1999 SL500 I've been struggling for weeks now.
For some reason, the top controller + windows controllers do not functioning AT ALL.
The LED lights inside the top and roll bar control buttons is constantly ON and solid red.
The biggest problem is I cannot close any of the doors because the windows are not functioning at all, meaning they won't lower down automatically to allow the door to open and close properly.
When I disconnect the battery and reconnect it after 5 minutes the issue is fixed and gone but keeps coming back after turning off the car.
Also I checked all the fuses in the car and they are all working perfectly.
I also attached the Hard Top back in hope the system will reset itself, the car sucked the hard-top in but it did not solve anything and now it's stuck in it's place lol (which is not a big deal I just want to solve the problem).
I'm attaching pictures of the problem and it also shows how the window did not lower down when I want to close the door (not to mention it does not work at all no matter what).
Please help! I really appreciate it!
Thank you in advance
