Hey guys. I have a 91 Z28, 305 TPI, auto, A/C. I've been told, and read here several places, that ALL 91 Z28's with A/C had a dual fan setup. Mine has a single fan. Only two relays up behind the brake booster (Fuel pump and fan), not 3 for (fuel pump, primary fan, and secondary fan). Can anyone shed some light on this for me? Anyone happen to know the RPO code for dual fans?

The relays by the Brake boosters are for fuel pump, MAF Burnoff and MAF power. The fan relays are between the radiator and the battery on my IROC. On my TBI RS the fan relay is where you describe and yes it had only 1 fan, but you have a TPI.
Here's a picture of what my relays look like near the brake booster.
Here's a link to RPO codes for 91 Camaros:

Sorry. I'm not real familiar with MAP cars.
At least the RPO codes were correct.
