Question about 1998 Buick Century
Buick centry with manual AC-heater control. I turned the fan control knob to high and immediately noticed an electronic burning smell. No output from the blower and the control panel lights dimmed until I turned off the fan switch. Could this be the resistor module?
Blower resistor is common to burn causeing smell. check with dealer, there may be a campain on this problem. if not. replace resistor and harness (pig tail) and blower motor..

First their is a blower motor resistor near the blower motor it controls and regulates the power going to the blower motor. This needs to be changed with the blower motor. If it was me and you want to fix your self with out taking to a shop I would change the blower motor and resistor. If this doest fix the problem you can return the items to your part store.One thing you can do is locate the resistor you will see the wires large ground and large power wires along with reg wires check to make sure it has power going to it on I believe 2 wires large power and small power wires if it does have power check other wires as you turn the fan high to low and see if anything. if you have power going to the resistor change them both. If this doesnt work and you still want to fix the modual should have 4 torx or 4 small metric bolts like 5.5 or 7mm remove them lift mod off. Just replacing most people do not recalibrate. At like GM they can put it on a scanner and check the operation of each part and they also reclibrate with the "Tech 2 scanner" . but first check the resistor for power if it has power change the resistor and blower motor

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.
