W123 power windows stopped working
 

Hello,

I recently bought a w123 from 1976 with power windows. The left rear window was verry stiff, but it worked. Until that the window was going stiff so we tried to help the window by pulling it up, when we did that the window got stuck and now and now none of the windows work anymore. The fuses under the hood are all intact, is there a place where there is a hidden fuse or would it be the relay? Or something else maybe?

Thanks in advance!
Kind regards, Roan
