Hey guys quick question. My 87 ss the Heater/AC control switch inside the car will not turn anything on. So could you give a couple of troubleshooting steps. Is there a fuse that controls that? I'm new to the G-body. I google the fuse panel but see anything that was labeled Heater. seems like all my switches are dead in that area.

switch controls the blower motor?

If there is no blown fuses or burnt/melted plugs check the relay & resistor on the heater box to ensure they are still completing they power circuits.
