Vette(s): 1989 coupe

Corvette Central has a bunch of Youtube videos of a stripped out C4 where they point out lots of hidden relays and other parts.  I would start there.

Vette(s): 1987 Convertible. Bright Red/Red Interior. Stock/Original.

On my 87, the Mass Airflow Relay is right behind the battery. I was getting the same code, and replacing the relay fixed it. Think it's the same on an 89.

The fan is running because the resistor on top of ac box is shorted.Unplug it and the fan will stop running .They sell them for replacement!!
