My blower fan is not working. Where is the air control module located at for a 1992 Seville STS? Thanks. I have tested the fan and it does work.

    The input is coming from an HVAC computer (sometimes on the BCM). Typically the gray/black wire to the module is the input from the computer. This should read nothing with the car off. If it still read nothing with the car on, and the controls set to have the fan on, the harness needs to be replaced. If it is fine, the module needs replaces. Voltage should be between 4-8 volts typically.

    Typically near the blower fan under the hood, near the firewall.
