SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.

SOURCE: '91 Buick LeSabre heater blower motor

Are you sure the blower motor is defective? If the blower motor resistor pack is bad the blower will not work. Have you applied 12 volts directly to the blower motor to verify it is bad? I have not replaced a blower motor on your particular car but it is usually a labor intensive repair. Depending on where you have it repaired the cost could be as little as $150 and up. Hard to say without actually doing it. Replacing the Resistor Pack is a fairly easy repair, so hopefully that is your problem.

SOURCE: 1997 buick lesabre HEATER PROBLEMS The fan

This could be several things. First I would check that the thermostat is not stuck open. This will condition will make the car run cold when it is cold outside.

If this is not the case........and I'm assuming you've already checked that the antifreeze is full, make sure that the heater valve is working. If it is frozen in place then it won't move and won't allow the warm water to circulate through the heater core.

I'm basing my answers on a standard Lesabre. Yours may not have the standard climate control.

2003 bick lesabre blower not working, changed both blower and resistor and fuses. Worked for a few days then quit.


Did you carefully clean out all the debris from the heater box? Did your new blower come with a new fan unit, or re-use the old one? Can you hear the motor run but not blow? These fans are fragile when old, and sometime break right where they attach, thus no blow. If not running, check for current at motor, then resistor, then fuse. Only thing left is the switch.

HEATER FAN DOESN'T WORK ALL THE TIME, WORKS SOMETIMES IF YOU SLAM GLOVE COMPARTMENT


DON'T slam the glove compartment, that's near the passenger airbag. Check fuses for the fan, and the motor for the fan. The fan works sometimes, which means power is getting to it, might just need to be cleaned or replaced.

NEED TO REPLACE THE HEATER FAN IN A 2003 BUICK LASABRE. PLEASE ADVISE IF FAN BLADE CAN BE REPLACED OR DO I NEED TO REPLACE THE ENTIRE BLOWER MOTOR & FAN? THIS IS THE INTERIOR FAN FOR HEATER AND AC.


the fan "blade" is a tubular rotating device that looks like a mouse treadmill. it can't go bad. if it is binding, free it. it is almost certainly the motor which will probably come with a new fan cage.

The engine cooling fans in our 2003 Buick LeSabre LTD don't shut off when speeds over 25 MPH are reached.


There is nothing to worry about. The cooling fans do not operate by engine speed, but rather engine temp. If the fans stopped working, then there would be a problem with either the cooling fan relays or the temp sensor which operates the fans. Otherwise, you are fine.

How to fix heater wont work in 1994 buick lesabre


It may be a fan resistor if the fan is not working or only working on one speed, the fan ressitor is about $40.00 and is usually located under the glove box on the heater box, look for the plug that goes to the resistor unscrew the hold down bolts unplug the old switch and install the new one.

Cruse control


Does your blower fan work on your heater/ac or your rear defrost work it could be the igniton switch were you put the key in. Turn the car on and off several times once you notice the cruise will not work and see if it starts to work if it does than it is the ignition switch this just happen to my 2003 century.
