mac,Welcome , welcome to nico ,step right up 10 cents admission
My two cents , that there is very little to go on as far as background info , car, make model yr. ......... much help here though ..give us a little more - you'll get it.
Offhand - your saying your belts went bad ? Only ONE serpentine belt ? A frozen pulley ?? That would "almost" account for everything ? A/C cluch seized- long enough to result in your

But see if water pump pulley spins "normally" ?? AND with A/C OFF- if normal serpentine belt operation ???
Now , brake Lt. ?, like in that Kinks song - "You really got me,really got me"
