SOURCE: In 97 mercury mountaineer, how to turn off "check engine" light

Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.

SOURCE: 2004 Mercury Mountaineer fuel gauge not working

The most likely failure that will cause your problem is the fuel level sender in the gas tank. The sender will cause both the fuel gauge problem and the check engine light to be turned on. The sender will need to be replaced to repair the problem.

SOURCE: brake lights stay on when vehicle shut off

The BRAKE LIGHT SWITCH needs to be Readjusted, Simply Move it Closer to Pedal Arm to Adjust. There is a NUT that you must Turn to do this. If you take a Good Look at it it is SELF EXPLANITORY.
I Hope this Helps , Well I Know it Will as it5 is OBVIOUS as to what the Problem is. Have a Good Day

SOURCE: I want 2 change 2004 mercury mountaineer transmission fluid

The best way to change it is to flush it out You can do it yourself, but I do not recommend. A shop that is good like a Monro or Firestone usually charges about 100 bucks to flush and that includes the fluid. If you do it yourself, you will save about 60 dollars, but you risk damage to your radiator.

you will need a hose and an adapter. you back out the lower, or upper cooler line for your trans, whichever is the easiest to get to, (Some trucks have an auxiliary engine oil cooler, but make sure you are flushing the trans lines) put the adapter into the rad where you removed the line, and put a hose from each one down into a bucket. Have about 14 qt's of ford trans fluid ready. Put the funnel into the trans dip stick, and start the engine. pour the qts into the dipstick tube while the old fluid is pumped into the bucket. When you have about two gallons pumped into the bucket shut the engine off and reattach the line into the radiator. start up the engine and check your level. Fill with additional fluid if needed.

note: some say you should drop the pan. two things, you only change half the fluid when you do it that way, and second if you need to change the filter because it is clogged, it is too late for the transmission. The filter is only there to protect the valve body, not keep the fluid clean.

Hope this helps
