Hello everybody, my 90exr eats up my a/c belt for some reason. Could the compressor be seized up or something? How could i resolve this.

 

I would make sure the belt is not too tight also I would make sure there is no marks on the pulley, maybe Someboy dented the pulley somehow.
Let the engine idling with the Hood popped and have someone turn on the A/C if the compressor is locked you should be able to see it.
Let us know what happens.
