Ignition Switch GM Century/Lumina/Grand Prix/Intrigue 1997-2000 The vehicles covered by this guide use one of two types of ignition switches:

  • A mechanical key and lock cylinder built into the steering column, that works a pull rod to actuate the separate electrical portion of the ignition switch mounted further down the steering column. For more information and replacement procedures on this type of switch, please see .
  • An instrument panel-mounted ignition switch is also used on some W-Body vehicles. To service this switch, the radio, heater & A/C control panel and the instrument cluster must be removed. All of these procedures are found elsewhere in this section.
REMOVAL & INSTALLATION
Instrument Panel-Mounted Ignition Switch
WARNING You must perform the Body Control Module (BCM) theft deterrent relearn procedure after replacement of the ignition lock cylinder. Failure to perform this relearn procedure means the BCM will not function properly. This means the vehicle will not be theft protected by the Passlock system and the engine may not crank or start. GM recommends that this procedure be performed with their Tech 2® or equivalent scan tool. An alternate relearn procedure is given at the end of this procedure.
  1. Disconnect the negative battery cable.
  2. Remove the radio assembly following the procedures found in this section.
  3. Remove the heater & A/C control head assembly following the procedures found in this section.
  4. Remove the instrument cluster assembly following the procedures found in this section.
  5. Detach the electrical connectors from the ignition switch.
  6. Insert the key and turn the ignition switch lock cylinder to the ACC position.
  7. Depress the transaxle park/lock cable retainer to release, then pull to remove the cable from the ignition switch.
NOTE You must perform the Body Control Module theft deterrent relearn procedure after replacement of the ignition lock cylinder.
  1. If it is necessary to remove the ignition lock cylinder from the ignition switch (theft damage, etc.), use the following procedure:
    1. Insert the key and turn the ignition switch lock cylinder to the ON position.
    2. Using a small flat-bladed tool, depress and hold the lock cylinder retaining tab.
    3. Using the key as an aid, pull to remove the ignition switch lock cylinder from the switch.
    4. Remove the key from the lock cylinder.
    5. Carefully pull to release the ignition switch bezel from the ignition switch lock cylinder.
  2. Remove the ignition switch bracket bolts and remove the ignition switch through the instrument panel cluster opening.
  3. Remove the bolts retaining the ignition switch to the bracket and remove the bracket.

This procedure takes approximately 30 minutes. Make sure the battery is fully charged before proceeding.
  1. Turn the ignition switch to the OFF position.
  2. Turn the ignition switch all the way from the OFF to the START position, then leave it in the ON position. The engine will not crank.
  3. The SECURITY light should come on and stay on for at lease ten minutes.
  4. Turn the ignition switch to the OFF position for five seconds.
  5. Repeat Steps 2, 3 and 4 again for a second time.
  6. Repeat Steps 2, 3 and 4 again for a third time.
  7. Turn the ignition switch to the OFF position.

SOURCE: 2002 pontiac grand prix-heater a/c blower only

When the blower motor resistor goes it will still usually work on the high setting because that bypasses the resistor.
First look on the passenger side below the glove box you will see 3 press-pins. You need to remove the 3 press-pins and the panel they are holding up.

Now you will se a bracket holding a bundle of wires and 2 vaccum hoses on the left side of the blower motor see pic. This is held on with 2 screws. Remove the screws and let the bracket hang off to the side.

Now remove the blower motor there are 3 screws to remove the blower motor a plug-in and a black hose. The black hose and plug-in you can not see from this side. You will kinda have to angle the blower motor and push the wire bundle out of the way to remove the blower motor.

Now with the blower out of the way remove the closest screw from the blower motor resistor. Disconnect the plug in from the resistor and carefully slide the assembly to wads you and it should pop down. There are a total of three screws that hold the resistor in but you only have to remove the one.

Now just reassemble the way you took everything apart. Hope this helps. I think the resistor is only like $20.00 at Auto Zone or Parts Source, they also have step by step instruction to.

Good luck

3 speed fan barely changes speed


You are talking about your blower fan for the air conditioner and heater right? More information will be needed to solve the problem.

When you say it barely changes speeds, does that mean it doesnt speed up, or doesnt slow down? By that I mean, is it "stuck" on low, or high?

Most blower fans run at different speeds through the use of a multi-stage resistor built into the fan switch circuit. Low speed is a high value resistor, medium speed is a low value one, and high speed is the fan running without any resistance.

If your fan is running on high and doesnt seem to want to run on lower speeds, the resistor pack may be failing. If the fan is running on low speed only, it may be that the fan itself is beginning to fail, or that the lubricant in it has gotten gummy.

The blower doesn't work for the a/c


Check fuses, then the relay. Fused power to the lower speeds, and a relay sends power to the fan for high speed. Some cars have an electronic blower motor for a variable speed system. The motor could be bad, or the motor board could be bad, if you have a variable speed blower motor. Very expensive to replace. 250 to 400 dollars. good luck.

Heater/ac on a 1995 sidekick dosen't work


old post, you mean the fan is dead.
yes,
if dead on high , bad fuse.
if fuse is good, then bad switch or fan.
if dead on only lower speeds, bad fan resistor

Blower fan low speeds don't work. Can only get the fan to work on position 3 which is too high. What might have happened such that positions 1, and 2 don't work?


it is the blower motor resistor. I do not know off of the top of my head if it is part of the climate control unit or external for your particular vehicle. However the symptoms match.

01 grand.prix ac fan switch only works on high. has a duel temp controller when you turn fan off the only way fan comes back on is to move the temp controller levers


Hi!!
When the Blower Motor Resistor (controls blower speeds) goes bad, the blower motor works only on HIGH SPEED. REPLACE IT.
BLOWER MOTOR RESISTOR Removal & Installation
  • Disconnect negative battery cable.
  • Remove right lower instrument panel insulator panel.
  • Disconnect blower resistor connector located behind right side of dash.
  • Remove blower resistor screws and blower resistor.
To install, reverse removal procedure
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

Fan switch only works on high


It is very likely that the blower motor resistor has burned out. The resistor uses several resistors to drop voltage which drops the fan speed. Since high speed requires no drop in resistance it bypasses all the resisitors. Since none of the lower speeds work I would belt that the resistor for the setting just under high speed has burned out out. since all the other lower speeds use that resistor. Sometimes they will also have a non-serviceable internal fuse that will blow.

Replaced fan relay but now lowing fuses


This might be a ground wire loose somewhere. Or a hot wire exposed to a ground. Electrical problems are the worst part of a car to fix. Try to replace just the wires or the entire harness to the fan relay.
Hope this helps.

Blower fan stops on lower speeds 2000 grand marquis


There is a blower realy. Which steps the voltage up or down. If it fails it will run 12 volts or HIGH speed only... Replace that and your good.

In the fuse/relay box under the hood in front of the battery are 3 fan relays. 1 for low speed, and 2 for high speed. 1 of high speed is back up. check the relays first.
B3 CHECK FUSES
  • Key OFF.
  • Check the 10A RELAYS fuse located in the interior fuse junction panel and the 65A RAD FAN fuse located in the main fuse junction panel. (engine compartment)

2005 jeep grand cherokee 4.7 Ac fan lost the 3 lower settings, only the high setting still worked. For a while the lower fan settings would just come on, and then go out again. The high fan setting...


Well, the blower resistor handles the lower speeds and the hi-blower relay handles the hi speed only. if the fan still works on the lower speeds then the resistor is bad. if the fan doesn't work at all then your motor has failed and or burn't the relay out also. if you can get your blower to start by hitting the kick panel above the pass. side foot area then the motor is bad. if you are handy enough to drop the kick panel and access the motor then check the connections at the motor. Then wack the motor and see if it comes on then. you will most likely find the problem if you follow those simple rules above. Good luck.
