Never heard of the rear one having a problem but on the front the whole
circuit including switch is overloaded at high speed.  My solution is to
run a separate fused circuit for high speed, switched by a relay.  You cut
the high-speed wire from the switch and use it to supply the relay control
voltage, then use the output of the relay to drive  the other side of that
wire.  Low and medium speeds are handled well by the original circuit, high
speed now only draws milliamps for relay drive and the power comes from a
separate circuit.  Then look and see if someone didnt' put a 25 amp fuse in
the original circuit, and if so replace it with the proper 16 amp
fuse.  Should be easy to find the fuse, it's the one where the cover is
melted over it...
