SOURCE: Radiator cooling fan doesn't come on.

first unplug the cooling fan at its plug and supply 12v to the fan if it doesnt run then replace if it does run follow the power wire to the thermal water switch usualy located at the bottom of the radiator.Use test light/probe to check that you have power into the switch and when engine is hot you should have power both in and out of the switch.if not replace thermal water switch.If that is working you will need to find out why you have no power to the switch.Check that your fuse and relay is working correctly.Sometimes just pulling out the relay and putting back in will make it work due to poor contact.Also try swapping relays with others in the same box near battery to identify if relay is faulty

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.

Where is the fan blower resister


Engine compartment, below the RH Maxi-Fuse Block. The Blower Resister/Control Module is hidden from view by the Maxi Fuse Blocks. But they are located to the left (as you are facing the engine compartment firewall) of the Blower Motor. See attached diagram:smogteacher_3.jpg

You need to replace the blower motor. Its on the firewall right side. OR maybe a loose wire on it. Check your fuse box also.

2000 BUICK LESABRE BLOWER MOTOR


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.
