You will need to remove the engine's valve cover at the rear of engine to remove the blower motor, also replace the blower motor resistor while you are in there.

Here's a guide to remove your blower,check your blower motor resister too,it's next to the blower,2 screws hold it on.http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0996b43f8038fb36&partName=Blower+Motor&partId=0996b43f8038fb36 Here's another link to relay.http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0996b43f8038fb36&partName=Blower+Motor&partId=0996b43f8038fb36 hERE'S THE RESISTOR.http://www.autozone.com/autozone/parts/1996-Pontiac-Bonneville/A-C-Heater-Blower-Motor-Resistor/_/N-j4ys1Z91tag?filterByKeyWord=blower+motor&fromString=search

Did you check the blower fuse ??

3. For 1993-99 vehicles, remove the nuts and cross brace bar.
4. Detach the electrical connections from the blower motor.
5. Disconnect the cooling tube from the blower motor.
6. Unfasten the screws securing the blower motor to the blower module assembly.
7. Remove the blower motor and fan assembly from the module.

Fig. 2: You can disassemble the fan from the motor by removing the retaining nut


To install:

1. If the fan was removed from the motor, position the fan on the shaft, then install the retaining nut. Tighten the nut to 12 inch lbs. (1.4 Nm).
2. Position the blower motor and fan assembly to the module, then install the retaining screws. Tighten to 5 inch lbs. (0.6 Nm).
3. Connect the cooling tube to the blower motor.

Hope this helped (remember rated and comment this).

The blower motor is accessed from under the hood at the passenger side firewall

blower motor doesnt work

The blower resistor is under the hood on the passenger side right on top the a/c box that is bolted
to the firewall.

it could be a fuse check the fuses if it aint a fuse most likely the blower motor

the blower relay is the third one from the left ,,under the hood on the firewall ... also the high blower resistor is on the center of the firewall ..behinde the relay bracket
