Auxiliary Blower Switch

WARNING: This page does not describe the selected car, but rather 24 other vehicles, including the 1987 GMC Vandura Special, 1987 GMC Vandura, 1987 GMC Suburban, 1987 GMC Safari, and 1987 GMC S15 Pickup. However, it is still accessible from the selected car via links, so may be relevant.

Blower switch is the only control provided for auxiliary A/C system. In the "OFF" position, blower is inoperative, even though refrigerant is circulating through evaporator core if main system is operating. To operate auxiliary system, simply select desired blower speed. Auxiliary blower may be used for air circulation when main system is not in A/C mode.
