Fan selector switch works only on high selection.

How do I remove the molded coverings surrounding the Fan Switch, Heat and Directions selectors so I can check the Fan Switch and why it won't work? Fan only works when selected to highest speed.

This is a typical  symptom of a failed blower resistor. These have multiple taps for the different speeds but the highest speed just bypasses the resistor completely; that is why it still runs full-tilt.
That resistor may or may not be inside the passenger compartment and could be accessible from under the hood, probably mounted on the firewall or under plastic hoods covering part of the heater/AC exchangers.
I'd recommend buying a Haynes or Chilton manual for your car that should cover the location of that part and perhaps give you information on how to best access it. The books are $17-$30 US and available on line or at any auto parts store and will earn their keep pretty quickly.

My low cool and low fan does not work. High cool and high fan works good. Is this something I can fix myself and if so, how?

If it is a Ford product the problem is with the ignition switch!!!!!!!!High cool function bypasses switch, Other speeds do not.
Your headlights might not be working either.

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.

Here is the info. I hope the pictures show up. please rate assistance. thx.

Air distribution within the vehicle is determined by the function selector switch position. Two airflow mode doors are used to direct airflow within the heater core and evaporator core housing. The function selector switch/cable assembly is used to position these airflow mode doors. Refer to Section 412-00 for description and operation of each of the system functions.
Function Selector Cable Assembly
The function selector cable assembly moves the airflow mode doors to the desired position using a 2-sided pull-pull type cable assembly. The function selector controls the cable movement. The end of the cable assembly attaches to the airflow mode door/temperature blend door actuating assembly which transfers the cable movement to the 2 airflow mode doors.
An electrical switch is incorporated into the function selector to notify the A/C switch assembly if DEFROST or FLOOR/DEFROST is selected. When DEFROST or FLOOR/DEFROST is selected, the A/C switch assembly will disable the RECIRC request button and send an A/C request to the powertrain control module (PCM) regardless of the A/C request button indicator ON/OFF status.

Fan which blows heat doesn't work when toggle at dash board is moved to high.

When your fan switch is placed in the high position, it feeds directly to the fan motor and bypasses the blower motor relay. If the fan is operating on speed 1-3, then you have one of two things wrong, either you have a blown fuse, or the fan selector switch is faulty on the high setting.

No heater fan 1999 chevy astro van

There is a vacuum line that is operated by your selector switch, it is located under the hood, roughly in the center, up against the fire wall. If the line has leaks, your selector switch will not work and therefore your blower doors will not open and your heat will not be directed to the cabin of your vehicle. Replace the line.
