SOURCE: where is the neutral safety switch on a 1998 buick regal?

Hi there:

The backup lamps will light whenever the ignition switch is in the RUN position and the transaxle is in REVERSE. On older vehicles, this function was handled by a dedicated switch with a name such as the Neutral/Safety Backup Light Switch, or something similar. This switch was designed to keep the engine from starting in any gear except PARK and/or NEUTRAL. The switch contacts also activated the backup lights when the transaxle was placed in REVERSE.

On the vehicles covered by this manual, the backup lamp control function is part of an integrated switch called the Transaxle Range switch (sometimes also called the Park/Neutral Position or PNP switch). In addition to turning on the backup lights, the Transaxle Range switches primary function is to transmit to the Powertrain Control Module (PCM) the driver's transaxle range selection. The PCM uses this information to control both engine and transaxle functions electronically.

The Transaxle Range switch is mounted externally on the transaxle. New service replacement switches come pinned in the NEUTRAL position and no adjustment should be necessary. Please note that if the switch requires adjustment, GM recommends that their special tool J 41545 Park/Neutral Switch Alignment Tool be used to properly adjust the Transaxle Range switch, if required.

Removal & Installation

  1. Apply the parking brake and block the front wheels.
  2. Place the transaxle gear selector to NEUTRAL.
  3. Remove the air intake duct to access the switch located on the top of the transaxle at the range selector cable and arm.
  4. Disconnect the transaxle range selector cable.
  5. Detach the electrical connectors from the range selector switch.
  6. Remove the range selector lever retaining nut and lift off the lever.
  7. Unfasten the range selector switch mounting bolts, then remove the switch from the transaxle manual shaft.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: location of thermostatic switch 1993 Buick Regal 3.8 motor fan motors don't run

The fans are controlled by the ECM and it uses the ECT sensor for temperature sensing, so if the check engine light isn't on the sensor is not the problem. You need to have an active test run on the fan system to see what code is returned. Have you tried powering up the fans at the relay?

Own a 97 buick system has blocked me from starting car?

Did you change keys? That car had a valet key which would only crank the car once. If you tried to use the valet key on consecutive starts it would disable the engine. If that's not the issue, I'm of little help. Good luck.
