my teacher looked at mine today , he is a ford tech , has been for a looooonnnnngggg time , he said just routinely unplug the connector and check for fluid , he says there is no point in having it fixed until i see any fluid in the switch , and i do not understand the purpose of the switch , on mine , the stoplight switch deactivates the cruise , i only know because i drove home on the freeway one day , with no stoplight switch because a kid broke it , and when i hit the brakes with my cruise on to deactivate , it just kept going as it was before , the cruise stayed on until the brakes has been applied for quite a while , and on another note , my buddies 01 Edge 2wd 5 speed has this switch on the master cylinder , it is plugged in and everything , and his does not have cruise
