You have to remove the cover thats underneath the glove box.Disconnect the plug from blower relay to motor.The blower motor has 9/32 or 7 mm screws holding it in remove thos and you will have to allow it to drop down and probably tilt it to remove it from under the dash. The cover under the dash has several small screws they should be 1/4 or 9/32 also and it will have a light coming through it be careful not to rip the light out. then reverse the process

How to remove and reinstall heater fan motor on a 2002 Buick LeSabre ?

remove the plastic panel underneath the passenger side dashboard area. This panel contains built-in retaining clips and simply pops off by hand.
remove three 8mm holding the blower motors assembly into the dashboard HVAC unit, use a 1/4-inch ratchet and an 8 mm socket. Remove the blower motor's electrical connector and discard the old blower motor. Install the new blower motor in the HVAC cavity and replace the 8 mm mounting nuts. Reconnect the blower motor's electrical connector and replace the plastic panel. Turn on the ignition and test the blower motor on all of the fan speed settings

In-operative Heater blower

These cars don't have a resistor per say. They are equipped with a blower module which is on the right end of the blower case behind the glove box. Much more expensive than the typical resistor.

I put a new battery in my car ('94 BUICK LESABRE) my heater display flashes and the heater doesnt heat up, worked fine before battery change.

I know in a lot of vehicles, the blower motor is attached to the firewall. If yours is beside the battery, they may be a chance something was unhooked or tore. It had to be something that was done when you changed the battery. I am not familiar with Buick Park Avenue's. Find the blower motor and check for loose wires. Check the fuse as well. I would say, from experience, it is a simple solution as a loose wire or blown fuse. It might have been perfect timing for the blower to go out. It does happen. Check the current on the blower with a voltage meter. If you need anything else, let me know. Thank you very much for choosing FixYa.

94 Buick lesabre, new blower motor and new control module. Blower stays on even with key out of ignition. What could be the issue? Relay or control module?

The only way for the blower to still get power with the key off...means the resistor to the blower motor is bad...The resistor is located on the firewall...under the plastic shroud...this should fix your problem...nice Buick...:)

I have a 1994 Buick LeSabre Limited with a blower motor that will not run. When I hook the motor up directly to the battery it works, and when I put a voltmeter on the plug that goes into the blower motor...

The blower motor fuse,or relay is not working,check these,and the blower motor switch.The relay is activated by connecting ground to the relay.Best bet,is the blown fuse.

The blower motor should be two wires. Backprobe and find out which is power and which is ground and bench test it. You could have a bad blower but it sounds more like a defective speed resister.
