From the 1997 Mercury Grand Marquis 4.6L SFI 8cyl repair manual, the Flasher is located behind left side of instrument panel. The turn signal and emergency flashers are attached to the interior fuse panel. They are replaced in the same manner as the fuses and circuit breakers.

The problem is most likely the contact ribbon under the steering wheel, it has a broken printed circuit ribbon to the horn button, it is referred to as the "Clock Spring Contact Drum"

When you say it wont start, it wont crank even a little bit? any clicking? i would look for an issue with the starter if the wires are getting hot, you could have a corroded ground wire which would cause a backup of electricity making the wire hot(simply put)

You may have a bad connection where the battery grounds to the frame and/or engine. Check the cable running from the negative battery post to where it bolts to the car. It should be clean and very tight - no corrosion. If you can see the connection, watch it while someone tries to engage the starter. See if it sparks, or starts to smoke or glow a dull red. If so, the connection needs to be cleaned up very well.

there should be a 'legend' on fuse box cover identifying locations specific to your model.blown fuses are readily identified when removed & inspected. after market radios usually have an 'inline' fuse on the power supply wire as well.

Could be a leaking hear core or hose that goes into the core.

1997 Mercury... | Answered on Jun 17, 2017


the lock isnt turning the back part which is the contact switch,use a screwdriver to turn it off or disconnect the battery. I think the problem lies in the barrel is got a piece broken that goes from the barrel to the contact switch .Without seeing it myself i couldnt tell you whats wrong or why the barrel has come out but their is a small hole in the case where you can push in to remove the barrel but in all honesty ask a local mechanic to have a look for you as this mat be beyond the average hme mechanic to sort out also their is a security reader that reads the chipped key callled a transponder so a local mechanic who knows what hes doing is your best best .Sorry if this appears a negative answer but as stated i would need vehicle in front of me to diagnose the correct repair.
