Question about 2000 Buick Century

1 Answer

My Buick 2000 is having electrical issues. The heater blower will work sometimes on high and other times when shut off can't get it running again. Now sometimes everything decides to work heater blower low speeds and high, all climate controls, and even the cruise. Then once vehicle is shut off does not want to work again. For some reason the cruise issue is tied into the heater blower issue at the same time. Any ideas?? thanks

SOURCE: location of blower resistor

The 96 LeSabre Custom and LeSabre Limited use an electronic module in place of a blower resistor.
It is under the hood on the firewall on top of the heater plenum, but below the relay rack.
They tend to short and run on high until the module burns out and then it quits.
The same part is used on many high-end GM cars from 92 to 96. The electronic module has two connectors on it. (If yours has only one plug it is a real resistor pack and not electronic.)

SOURCE: Blower motor vent selection switch not working

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

SOURCE: 90 buick park ave heater blower motor runs on high

The switch , relay, or motor are shorted out .
First locate relay and remove it to turn the blower off.
If you want to do the diagnosis yourself ...remove the switch first and see if the motor stops. if it does you've found the culprit. If not move onto relay if the relay removal kills the motor thats good news. if it doesn't then this thing gets B+ right from the battery at HIGH SPEED. Your gonna need Shop Manual
to show you where this thing connects to the battery.
So either the switch, relay, motor , or resistors ( in your case where battery connects to the motor are your problems.
Unlessyour really good with electrical items pull the relay and bring it to a repair shop.
