I have a 1982 500sl conv (gray market) car. All of a sudden, both the power windows quit working at the same time, went out one day and they would not work, i think the battery was low and i had to charge it to get running, would this have anything to do with it?

I tested the fuses, they are good, called MB they said check the relays above the fuse box(passenger side foot well), i switched the three relays around in each plug, but the windows still won't work.

Is there any other place i can find fuses or relays, like under the hood?

any help will be appreciated, all other electrical parts work.

thanks in advance
