Three 7mm bolts holding it in under the passenger side of the dash. the two bolts closest to the front of dash of motor are very easy to get to. but the back one is buried and can be difficult to get to. i usually use a 1/4 drive ratchet and extension with a swivel to get to it. at the same time you will need to push back the under rug padding that meets the firewall right were the motor is.

now i replace my share of these but i also see alot of blower resistor go also. a sure sign of this issue is the blower will only work on high and no other setting. if this is the case then you need a blower resistor but if not then the motor wil need to be replaced. so if you have any more question please ask. good luck

    okay very simple. this job will take less than half an hour to complete. from passenger side of vehicle locate blower motor under the dash in the heater box. it is at the very lowest point mounted in the heater box by three 7mm screws (gold color). it has a two wire connector going to it one black and one red they are heavy gauge wire ( 12 gauge to be exact). depress connector release tab and pull the connector out. then remove the three screws and the blower motor will come down and out towards the passenger seat (pull down and reward). once removed the installation is in reverse.

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.
0900c15280090fea.jpgRemoving an instrument panel-mounted ignition switch assembly—1998 Oldsmobile Intrigue shown, others similar To install:
  1. Install the ignition switch to its bracket and install the bolts. Install the ignition switch into position through the instrument panel cluster opening and install the bracket retaining bolts.
  2. If removed, install the ignition switch lock cylinder to the ignition switch using the following procedure:
    1. Recode the lock cylinder, if necessary.
    2. Align the ignition switch bezel to the tabs on the ignition switch lock cylinder and carefully press to secure in place.
    3. Insert the key and turn the ignition switch lock cylinder to the ON position.
    4. Align the ignition switch lock cylinder to the ignition switch, then press into place.
  3. Turn the key to the ACC position. Align and press into place the transaxle park/lock cable to the ignition switch. Remove the key from the switch.
  4. Attach the electrical connectors to the ignition switch.
  5. Install the instrument cluster using the procedures found in this section.
  6. Install the heater & A/C control panel using the procedures found in this section.
  7. Install the radio assembly using the procedures found in this section.
  8. Connect the negative battery cable.
  9. If the lock cylinder was removed, perform the BCM Programming/RPO Configuration procedure.
THEFT DETERENT RE-LEARN—WITHOUT TECH 1®SCAN TOOL
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.
  8. Turn the ignition switch all the way to the START position. The engine should now start.

How do i remove and install a water pump on a 2000 pontiac grand prix


obviously you need to take off the serpentine belt. realistically you can get at all the water pump bolts. but for more visibility, I took off the coil pack block (held on by two bolts) I also took off the alternator and the piece that the belt tensioner and heater hoses are attached to. not that you need to but you can also take off the power steeering pump. Do not take off the hoses. the pump has holes in the pulley that you can put a deep well socket through. #14 I believe. I just replaced the motor in my grand prix
