Service engine soon and lost brakes

Are you not familar with check lights or fords MIL Lamp
you have lite?

Have to take to a repair shop any time you start the engine
and any dash light stays on- means you have a possible system

Now any type of braking problems I would assume you have it
parked & are not using it

Has to be checked for codes & code related issues resolved
first,those may also be related to the brake problem,but there
is no way you loose brakes unless a brake line rusts thru & is leaking

I have a 2003 Mercury Mountaineer with about 105K miles on it. I love the car, and want to keep it. I have several issues: 1. cruise control works intermittenly 2. dvd player does not work 3. abs...

#3.I replaced the hub bearing assembly on drivers side twice and the light stayed on and the brakes worked fine. It was the wires (visible just above the tire on the frame) that rubbed against the frame that had shorted out. It was simply repaired and clip-stripped up out of the way. The light has been off every since then.
#4.Go to an autozone or another auto store and they will plug in to your diagnostic port for free and give you any answers on any codes that come up. My light came on at 133kmi. and i disconnected the battery and it has been of since then. Although you should get some things serviced soon such as tune-up,transmission and general maintenance.
#2.My dvds get stuck and it works about 75% of the time. I just keep pushing the buttons until it plays. They are just junbk and need to be replaced.

03 mercury mountaineer, service engine soon light came on. i was told it needed a oil change . we did that , now how do i get the light to go off ?

Your Service Engine Soon light has nothing to do with reminding you to change your oil. The light is controlled by the ECM (Computer) in your vehicle. It monitors various sensors in your engine and compares them to variables or programs that is in its memory. When something is not registering correctly or is outside of its parameters it will turn on a MIL(Malfunction Indicator Light)or in your case a Service Engine Soon light. You will need a OBD II ( On Board Diagnostic) reader or scanner to hook up to your diagnostic port under your driver's side footwell to read what code the ECM is putting out. Than with the code the mechanic can look up the code to see what part is sending a malfunctioning. The scanner can also read and erase the code too. You can have your code pulled up with a OBD II scanner for free from any AutoZone store.
