Where can I find the relay switch that controls the speed of the dasboard fan on a 1998 Chevy Malibu ? Also is it difficult to replace ? The car's mileage is 125,000. Thank You.

You have a Blower Motor Resistor that controls the speeds of the motor. If the motor runs in high, but doesnt in one or more of the lower speeds, suspect that resistor as your problem.
To replace it you must remove the blower motor, and it is in the ducting behind the motor. It is bolted to the outside of the ducting, with the resistors in the air stream. You may have to cut the dash mat a little bit to gain access to the back screw.

Suggested Repair

If the blower runs on high but not on one or more lower speeds, replace the blower motor resistor. Remove the blower motor; the resistor is bolted to the outside of the duct behind the motor, with the resistors in the airflow. The dash mat may need a small cut to reach the rear screw.

Conversation Summary

The owner of a 1998 Chevy Malibu with 125,000 miles asked where the dashboard fan speed relay is and whether it is hard to replace. The expert said fan speeds are controlled by the blower motor resistor, which is the likely fault if high works but lower speeds do not. It sits in the duct behind the blower motor and is accessed by removing the motor; a small cut in the dash mat may be needed for the rear screw.
