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.

Replace blower motor on buick lesabre 2004


It is located under the right side off the dash. Remove the plastic kick panel and you will see it. The screws to remove the panel are just under the glove box. Once the panel is removed you will see the motor housing it has an electric plug with three wires.

Where is the fan(blower control module) located on a 1993 Buick LaSabre the fan motor runs on high all the time even with the key off. this car has the automatic A/C-heater system


The blower control module is located under the hood along the firewall.It is about a foot from the blower motor.(more towards the passenger side) It is harder to see as the relay center is directly above it.

A/C Heater blower fan does not cycle through all speeds


Yes it is the blower Motors Resistor board. It is up behind the blower motor, just under the glove box. You have to remove the black KICK panel with its two "Push Pins" that will break too. There are 3 screws holding that resistor board in, the back two are a bear to get to. Good luck.
