I HAVE A 1997 MERCURY SABLE, ONE OF THE PROBLEMS IS THAT THE REAR TURN SIGNAL AND HAZARD DON'T WORK, ONLY THE FRONT ONE ARE OK.FUSE IS OK,BULBS ARE OK, TURN SIGNAL FLASHER OK TOO. THE SECOND PROBLEM, WHEN THE CAR IS IN PARK OR NEUTRAL THE RADIO AND POWERED WINDOWS WORK,BUT WHEN I PUT IT IN REVERSE OR DRIVE THEY STOP WORKING THANKS FOR YOUR HELP

you need to check to see which bulbs don`t work both front and back lights for the signal on the side it`s not working,you don`t say if any signals work or not if no signals work then you need to check the fuses under the dash on the driver`s side.now if it`s just one side then check the lights as mentioned above.if one isn`t then replace the bulb.if neither bulb is working then it sounds like the signal flasher is not working.turn on the hazard flashers and check the lights front and back.if all bulbs work then leave the hazards on and look under the dash for the flasher that is making the noise,this will show what the signal flasher will look like,then find the signal flasher on the fuse panel under the dash it should be located on the fuse panel.and replace

The hazard flasher switch is the flasher unit. If it's not working you might work the switch many times and the regular turn signals may start working and your done. This flasher is in the fuse panel near the steering collum

most likely flasher relay, just did this to son's car (Thunderbird). Most vehicles are in fuse block but his his was on bracket behind dash above accelerator pedal, very hard to get wiring clip off and expensive, $38, had to order.

It's a bad connection on the front balb u replaced or u might need to replace the light assembly as they corrode pretty bad.

Bulbs or Bady GROUND

Look for cut wiring or loose plug assembly in trunk area (behind panels).

the turn signal problem sounds like the multifunction switch (the turn signal switch) is bad as far as the radio and windows it sounds like the trans range sensor is bad it is located on top of the trans at the shift linkage

If you have checked Power/Ground, and alls good look toward the Multi-Function Sw. (turn sig.sw) this is where everything get distributed at...as for your power loss when shifting, is it column/floor shifter ???? need to know....

The flasher module is responsible for the flashing of the turn signals and hazards. this device will fail overtime. you will need to replace this failed module asap. Replacing the flasher will restore the signal functions in this vehicle. (Check the bulbs before replacing the flasher)

they are under the dash, but its highly unlikly that both would go bad at the same timeyour promlem is probly in the steering colum
