I have a 95 3.8 v6 mustang its my first car and the rear brake lights aren't getting any power what so ever.

Also the driver window goes up but it doesn't go down without massive assistance, and both front speakers don't work at all. I don't know if these are all mounted on the same circuit or if its just a coincidence. Any help is appeciated

Check the brake switch on the brake pedal that might be malfunctioning. The window it probably unrelated
