Mercury Mystique

The problem could be the starter. It's tough to say without seeing the car. The best option would be to bring it to a mechanic, who could correctly diagnose the problem.

easiest way is to take it to a transmission place. trick is to pretend that you know (unless you actually DO know) exactly what problem is and tell them to fix only that! obviously they will try to tell you its this. or its that. not more than 3 days ago i had to get the speed sensor done and they tried telling me my tranny has internal probs and they want 1800 to 2200 dollars to fix it. as it was they charged me 250.00 to fix speed sensor and that fixed everything. DO NOT go in and let them know that you are unknowledged. they will F$$#CK YOU at any chance they get. (unless you know a good mechanic, there are some out there)

under the instrument panel on the drivers side ( and the Power Distribution Box is in the engine compartment on the drivers side )

An on / off switch , fuel pump inertia switch , bad fuse etc

look under the dash on drivers side they may have tucked it up near the fire wall you may have to take off trim pieces or it may be in the glove box. The interior fuse box is below and to the left of the sterring column. There is also a fuse block by the battery under the hood. There is also (usually) a circut breaker by the fuse box that you may need to push.

There is actually two speed sensors on this car, I recently bought the two. If get under your car and look at where the axle comes out the transmission to the passenger side wheel, look just right above that and you can see it, the wires where it connects to lay just right on top of then trasmission. It's really close where the shift cable is. So look for the shift cable (you can see from the top) Look for the axle (from under the car) it is right there on that area. (you can only see it from under though)

To change the thermostat on a Mercury Mystique, first ensure the engine is cool and disconnect the negative battery cable. Drain the coolant and remove the necessary components to access the thermostat housing, typically located near the engine block. Remove the old thermostat and gasket, clean the surfaces, and install the new thermostat along with a new gasket. Finally, reassemble everything, refill the coolant, and reconnect the battery.

In the 1999 Mercury Mystique, the transmission breather hose connects to the transmission case, typically located near the top of the transmission. This hose allows for the release of pressure and helps prevent moisture and contaminants from entering the transmission. Properly maintaining this connection is essential for optimal transmission performance and longevity.

If your turn signal has stopped flashing, it may be due to a burned-out bulb, a faulty relay, or an electrical issue. Check the bulbs first to see if they need replacement, as a single burned-out bulb can disrupt the entire circuit. If the bulbs are functioning, inspect the relay and wiring for any faults. If you're unable to identify the problem, it may be best to consult a professional mechanic for further diagnosis.

Yes, a blown fuse can prevent the alternator in a 1999 Mercury Mystique from receiving power. The alternator relies on electrical connections that may pass through fuses in the vehicle's electrical system. If a fuse related to the charging system is blown, it can interrupt the flow of electricity needed for the alternator to function properly. Checking and replacing any faulty fuses could resolve the issue.
