Is the transmission range sensor the same thing as the neutral safety swith, if so this was replaced, and the problem persists. not as bad as previously. is there another solution to losing all three in reverse.
1997 Mercury Sable
After starting and shifting the auto trans into drive the Radio goes off immediately. After 15 to 20 minutes of driving there is a clicking from what appears to be a relay near the the steering column or in the vicinity of the drivers "kick-panel". The power windows fail, the control console for the windows quits illuminating, Power steering works on an intermittent basis, Also the rear defrost switch on the dash panel will not engage or function. Otherwise the car runs exceptionally well! The engine never quits (Which I have been expecting any moment). The RPM Gage stays at the correct level with proper idling. Any Ideas? I am thinking the "Neutral Safety Switch". (How difficult and how do you replace this part? I am somewhat mechanically inclined, but prefer some input before I do anything).
If any mechanic agrees or has suggestions thanks in advance for your help!

when you park the truck dont move mean is on park but the range sensor is not working to make the by pass to make the truck to start posible you need to replace the range sensor or neutral safety switch
There isnt a neutral safety switch. There is a manual lever position sensor(MLP). It combines all the fuctions of backup lights, neutral safety, and informing the PCM what gear you have selected into one unit. Follow the shift cable out to the transmission, and at the end,
Follow the shift cable out to the transmission, and at the end, you will find the MLP.
Pendin if its auto or manual
It sounds like your transmission range sensor. It tells your transmission what gear your in and what gears to switch to when driving. It is reading that your not in park unless you move your shifter. You need to have it adjusted or replaced. If you want to take a look at it, it is located on the side of the transmission with a cable running to it. Just a little box like thing.
The transmission range sensor aka neutral safety switch is located underneath the air filter on top of the transaxle and very easy to access. Replace this part (around $50) and it will solve your problem.
What happens is this, when your tranny warms up, it disperses heat to the sensor switch and if its faulty or worn out, will send faulty relays to the transmissiom computer module (TCM) and makes the transmission shift irratically (OD to 3rd and back while driving at freeway speeds). You tranny is not overheating like most people believe, its the switch. Mechanics are telling alot of people that their tranny needs replaced. Watch Out For These People!! They only want your money!!
The switch has to be adjusted with the car in the neutral position, on the switch there are line up marks. Once the lines are in the same position tighten the bolts and then try to start in the park and neutral positions.
Hello and thanks for using FixYa!, the problem with your sable is that the transmission range sensor needs to be replaced, back in 1996 and 1997, the circuitry internal to the sensor caused an interference with several other systems in the car, including the radio, power steering and power windows. Have the sensor replaced and it will need to be adjusted, so it is best done by a ford dealer who would have the proper alignment tool.
