Mercedes: 560SL 1988 window relay?, hazard switch, fuses

Question
In my 560sl a 88 model, both windows do not work after the car has set up a while.   Had to charge the battery and after reinstalling it the door locks locked automatically  ( strange )  Anyway now the windows do not work?  fuses are good are there any relays that control the windows and if so where are they at.  Thanks for your help

Answer
Spin the fuses in their holders = break any corrosion at the tips.

Remove the switch and test for power at the connector.

If you have power, clean the switches, the following link will show you how.
