450sl window problem
 

Both windows in my 1980 450sl have stopped working at the same time - One day they both worked, the next they didn't, a week later they did again, and then they stopped working alltogether - checked both fuses (seperate for each window), and both switch regulators - any ideas

This car has a power window relay, I think. You will have to get a wiring diagram out and pull the right lower dash panel for access.
