WARNING: This page is about a different car, the 2002 Saturn LW300, 2002 Saturn LW200, 2002 Saturn L300, 2002 Saturn L200, and 2002 Saturn L100. However, it is still accessible from the selected car via links, so may be relevant.

Remove HVAC control head. See HVAC CONTROL HEAD under REMOVAL & INSTALLATION. Using a DVOM, check continuity between terminal A3 and terminal A1 at HVAC control head. If continuity is present, A/C switch is okay. If continuity is not present, check A/C indicator bulb. If bulb is okay, replace HVAC control head.
