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: 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

SOURCE: ABS light on a 2004 Mercury Mountaineer. How do I

Go to Autozone or Oreillys and see if they have a scanner for the ABS system. They usually scan for free.
The ABS will measure braking problems and things like worn brake linings and debris on wheel sensors.
You would want to verify the code light and then have the lining visually inspected.
There can be problems with the emergency brakes which require the rear rotors to be removed from the vehicle. Some of the rotors are a problem to remove because of rust.

2003 mercury mountaineer check charging system won't start

How can you decide if it is worth fixing if you have no idea what is wrong, it could be major or minor issue. Have it diagnosed before you decide. If it is not running the value of the truck is zip.

Check charging system

you need to check your charging system... check the date on your battery, inspect all connections and power leads. with car running test power leads with a voltmeter, normal operating threshold is around 14v while running.

Installed new battery, battery light keeps coming on showing no charge.

Take it to local parts store and have them do a FREE charging system test. I suspect a bad alternator or something as simple as a loose or glazed fan belt

My "check charging system" keeps

first thing you should check is the battery. to do this you should buy a multimeter from a parts house and set it on volts. with car off check charge of battery. it should read 12 volts. start car and retouch red probe to positive and black probe to negitive. it should read 13 to 14 volts. if it still
reads 12 or anything below 13 volts you need to replace alternator. also check wires from alternator to see if any are loose.
