    When that white plug in the back rear right quarter get corroded the fan certainly does not work as expected and when they're corroded and broken it doesn't come on at all . It forces you back there to fix it jumper it something I now in the four twos here the fans seem to work as expected . I'm in the 100 not blowing batteries . We also not hard on car I other cars to beat on.
