I'm trying to find the fuses that control the window operations. Originally the lf and rr were working and the rf and lr were not. I messed with all of the fuses and then the rf and lr worked and the others did not. I then cleaned the contacts on all of the fuses and now the lf and rr are working again and the other two are not. I'm not sure where to look next. Any thoughts would be appreciated.
