Check for a broken wire or a loose connection.

SOURCE: 1999 mercury mystique check engine light

Why my Check Engine light comes on?
The engine computer or PCM/ECM
All modern vehicles have a computer or the ECM (Electronic Control Module) that controls the operation of the vehicle powertrain (the engine and transmission). The main purpose of this is to keep the engine running at top efficiency with the lowest possible emissions. With constantly growing demands for better fuel economy and new strictest emission regulations it's not very easy to achieve. The engine parameters need to be constantly and precisely adjusted according to various conditions such as speed, load, engine temperature, gasoline quality, ambient air temperature, road conditions, etc. That's why today's cars have much more electronics than in early days - there is a large number of various sensors and other electronic devices that help the vehicle computer or ECM to precisely control the engine and transmission operation and monitor emissions.
The vehicle computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. To properly diagnose what is wrong, you need to take your car to a mechanic or a dealer. The technician at the dealership or a garage will then hook up the scanner to the car computer and retrieve the stored trouble code(s). Then he (she) will look it up in the service manual provided by a car manufacturer. The service manual contains the list of possible codes (about few hundreds) and describes what each code means and what needs to be tested. The code itself doesn't tell exactly what component is defective - it only indicates where to look, what engine parameter is out of normal range. The technician will have to perform further testing to pinpoint a defective part.

Welcome to the world of modern technology, where the vehicle manufacturers are having a race to see who can do the best job of keeping a vehicle owner from diagnosing something as simple as a light circuit! In an attempt to FORCE them into the dealership repair shops. Please check out this web site: Right To Repair

Okay - Here's how the manufacturer has succeeded in deterring any DIY attempt to repair your park lamp circuits:

The light switch does not actually switch the lights on or off. The light switch is actually a small computer that sends a digital signal to the Body Control Module (BCM) to tell it that you are "requesting" that the lights be turned on.
The BCM (if it decides to comply) then sends a digital signal to the Totally Integrated Power Module (TIPM) This is the thing under the hood that most people would call a "fuse box", however, it also contains a small computer. Fuses M17 and M18 in the TIPM are what provide power (protect the circuits) for your park lamps (both are 15 Amp fuses). I am assuming that these are the fuses that you checked. Please note that these fuses are "switched". They only have power when the power is turned on by the TIPM, and this only happens when the BCM tells the TIPM to do so.

If you are checking the fuses with the ignition switch in the RUN position and the headlamp switch in the PARK or HEADLAMP position and there is no power at these fuses, you will have to use a scanner that can read the data from the BCM to find out why.

If your headlamps are working, I would say that he problem is not a data communications problem between the headlamp switch and the BCM or between the BCM and the TIPM. It will most likely end with replacement of the TIPM, but then, the data really needs to be checked before replacing ANYTHING.

95 MERC MYSTIQUE,STUCK IN PARK, DID THE MANUAL OVER RIDE SCREWDRIVER TRICK, GOT IT IN NEUTRAL LOADED CAR ON TRAILER UNLOADED NEW TIMING BELT SET, STARTED RIGHT UP BUT NOW STUCK IN NEUTRAL


Do your brake lights work? Your brake pedal switch supplies power to the shift solenoid to alow you to shift. When you push the pedal do you here a clicking in the Shifter? The fuse might have blown, it is in the interior fuse panel possibly listed as shift interlock.

Only one window works. when I plug in master switch it blows fuse 23 to blower motor 98 mercury mystique


If you are mechanically inclined, disconnect the harness to the blower motor. Install the fuse and see if it blows. If not, your problem is from the switch to the motor. You may have a wiring problem, or a bad motor. With blower motor disconnected, check power to the harness, both the power side and the ground side. This will eliminate the switch as the problem.

98 mercury mystique oroblems


Two different problems. Check the linkage between the ignition switch and the transmission interlock. Also check for a brake-light interlock - if the brake lights don't light when you press the brake pedal, the brake light switch may be the cause of that problem.

As to the fan... are we talking about the heater/AC fan or the radiator cooling fan? Either may be as simple as a blown fuse - check the fuseblock under the hood.

I have 1996 mercury mystique and both break lights are not working?


Power for the combination turn/stop lamps is routed through the combination switch. If the rear turn signals work but the stop lamps do not, I suspect a combination switch failure

What number fuse is my brake lights in a 1998 mercury mystique fusebox


Sounds like loose wiring to either the earth or Postive connection in the main running wiring. rechk all connections particuarly yr pull off/on connections. Most fuses run at 10A for lights, but this depends on how many using this fuse. Chk that power is getting thru to various points with a meter, this will show u where the porblem lies. cheers

Shifting lever get stuck on p position?How to drive of parking lot?


The shift interlock system isn't allowing you to get it out of park. Make sure you are depressing brake pedal. If it still isn't working check to see if your brake lights (all of them including the 3rd brake light in the back window) are working, If none are working check to see if a wire broke at the stop light switch down by the brake pedal otr if you have a blown fuse.

Brake lights for a 1996 Mercury Mystique


The "multifunction switch" is bad. In the old days, this was called the turn signal switch. The brake light wiring for the two non functioning lights goes through this switch. Have your mechanic check the wiring into and out of this switch. It's in the steering column.

1998 Mystique brake lights don't work while the window brake light does work.


Try a continuity test, not sure where to find the electrical scheme but if you obtain it, use a tester or borrow one to test the continuity of the wires of both taillights, could be simple as a cut wire.

Tail break lights don't work. Window break light does work however. Bulbs have been replaced.


Check the brake light fuse. The high mounted brake light (third brake light) is on a different circuit than the brake lights. Hope this helps.
