Question about 1998 Pontiac Grand Prix

In the console what is the component attached to

In the console what is the component attached to the shifter? Ia it the neutral safety switch? Is this the only assembly that controls the engine from turning over if everything else seems to be ok.

The problem with the car is that is does not want to start but by moving the wiring in the console and playing with the shifter we can get the car to start.

    The neural safety switch was replaced, the starter has been replaced. The engine will stpll not turn over. The battery has also been replaced. With the key to the on position all everything looks normal. When the key is turned to the start position nothing happens. I can however hear a relay engaging on the left side inside the car just to the right of the glove box. No other sound.What do I do next?

Shifter on my gmc envoy xuv 2004 is stuck in reverse and I can not press the button down or move the shifter plus it won't start


This is usually caused by failure of the shift lock solenoid. It is powered by the brake switch. Check power from fuse 25, thru the brake switch to the solenoid, which is in the shifter.

Automatic transmission does not go out of park. change brake switch no help. need to find interlock control unit. could it be the neutral safety switch.


The transmission is locked into park by a solenoid activated little pin that stops the shifter from moving. It is attached to the shifter area under the console. You say you replaced the brake light switch, but did you check the brake lights to see if they work?

What is a neutral safety switch?


The Neutral Safety switch monitors the position of your gear selector lever and either interrupts or allows the starting circuit in your car or truck to do its job. On newer vehicles it may also monitor the position of the brake pedal to make sure that the vehicle is in park or neutral AND that your foot is on the brake.

If your vehicle is equipped with a neutral safety switch, it should NOT start UNLESS the transmission is in Neutral or Park. On the other hand your vehicle SHOULD start when it is in Neutral or Park. If your car will start in Neutral but not in Park, you have a bad switch. Also, if your car or truck will only start by turning the key to the start position and wiggling the gear selector lever, your neutral safty switch is in need of replacement.

The nuetral safety switch is usually found near the gear shifter. If your car has the gear shift on the column, then the neutral safety switch is usully mounted on the steering column near the brake pedal. On floor mount or console mount vehicles you will find the nuetral safety switch mounted near or on the shifter mechanism.

Neutral Park/BackUp Lights Switch - REPLACEMENT & ADJUSTMENT
  1. Remove the console trim from the console.
  2. Disconnect the electrical connector from the switch.
  3. Remove the 2 attaching screws from the switch and remove the switch.
  1. To install a new switch:
    1. Place the switch onto the transmission control shifter and loosely install the attaching screws. Position the transmission control shifter assembly in the N notch in the detent plate.
    2. Assemble the switch to the transmission control shifter assembly by inserting the carrier tang into the hole in the shifter lever.
    3. Install the attaching screws and tighten.
    4. Move the transmission control shifter assembly out of N position. This will shear the switch internal plastic pin.

  2. To install the original switch:
    1. Place the switch onto the transmission control shifter and loosely install the attaching screws. Position the transmission control shifter assembly in the N notch in the detent plate.
    2. Rotate the switch on the shifter assembly to align the service adjustment hole with the carrier tang hole. Insert a 3 / 32 in. (2.38mm) diameter gauge pin to a depth of 9 / 16 in. (15mm) and tighten attaching screws.
    3. Remove the gauge pin.

  3. Connect the electrical connector to the switch.

20 amp fuse in ACC slot keeps blowing


ACC slot is the Accessories slot. Perhaps there is a short or overload condition in the vehicle with the cigarette lighter or an add on electronic device.

Try to connect the two posts of the solenoid to see if bypassing the key cylinder works the starter. If it does, then this points to the key switching problem for the starter to the solenoid.

Also, check the neutral/back up safety switch:

  1. Remove the console trim from the console.
  2. Disconnect the electrical connector from the switch.

How to replace neutral saftey switch on a 1980 cadillac deville?


Use like reference guide for GM Cadillac 1967-1989 Repair Guide Neutral Safety Switch - REMOVAL & INSTALLATION

All Except 1985-89 Eldorado and Seville
See Figure 1
The neutral safety switch prevents the engine from being started in any transmission position except Neutral or Park. The switch is located on the upper side of the steering column under the instrument panel on column shift cars, and inside the shift console on floor shift models.
  1. Remove the console for access on floor shift models.
  2. Disconnect the electrical connectors.
  3. Remove the neutral switch.

To install:
  1. Place 1967-70 column shift lever models in Drive, and 1971 and later models in neutral. Locate the lever tang against the transmission selector plate on column shift models.
  2. Align the slot in the contact support with the hole in the switch. Insert a 3 / 32 in. (2.38mm) diameter pin in place. The switch is now aligned in Drive position.

1973 and later neutral safety switches have a shear-pin installed to aid in proper switch alignment so that insertion of a pin is unnecessary. Moving the shift lever from Neutral shears the pin.
  1. Place the contact support drive slot over the drive tang. Install the switch mounting screws.
  2. Remove the aligning pin. Connect the electrical wiring, and replace the console.
  3. Set the parking brake and hold your foot on the service brake pedal. Check to see that the engine will start only in Park or Neutral.

ADJUSTMENT
See Figure 2
1974 and later cars do not have a neutral safety switch. Instead, these cars have an interlock between the lock and the transmission selector, which is non-adjustable.
  1. Place the shift lever in Neutral.
  2. Move the switch until you can insert a gauge pin, 3 / 32 in. (2.38mm) diameter, into the hole in the switch and through to the alignment hole.
  3. Loosen the switch securing screws. Remove the console first, if necessary.
  4. Tighten the screws and remove the pin.
  5. Step on the brake pedal and check to see that the engine will only start in Neutral or Park.

Fig. 2: Adjustment of a common neutral safety switch


1985-89 Eldorado and Seville
See Figure 3

All neutral safety/back-up light switches come with a small plastic alignment pin installed. Leave this pin in place.
  1. Place the shifter assembly in the Neutral position.
  2. Remove the shifter lever-to-switch nut and the lever.
  3. Disconnect the electrical connector from the neutral safety/back-up light switch.
  4. Remove the neutral safety/back-up light switch-to-transaxle bolts and the switch from the vehicle.

To install:
  1. Position the shifter shaft in the Neutral position.

If using an old switch or the plastic pin (new switch) is broken, install a3/32in. (2.38mm) diameter pin gauge (drill bit) into the neutral safety/back-up light switch; the switch is then locked into its Neutral position.
  1. Align the flats of the shifter shaft and the neutral safety/back-up light, then, align the switch-to-tang on the transaxle. Torque the switch-to-transaxle bolts to 22 ft. lbs. (30 Nm). Remove the pin gauge.
  2. To complete installation, reverse the removal procedures. Make sure that the engine starts only in the Park and Neutral positions.

Neutral safety switch


Go to Autozone.com, and see their repair guide for the neutral safety switch. It is not in the center console, but under the hood, in front of the transmission.
