NG 900/9-3 Engine Bay Relay Panel

Location

In the engine compartment, next to the LH strut tower. The lid is attached by plastic snaps and can be removed for inspection and testing easily. The relay panel in its box can be detached with all wiring attached, and swung out of the way, for access to the clutch cable and the power steering line connections at the steering rack.

Relays

The panel includes relays for the lights, radiator cooling fan, A/C compressor, and on some of the "S" (2.3l non-turbo) models, the secondary air injection (SAI) system.

The orange "relay" is actually an electronic module with circuit boards inside, and can sometimes be repaired instead of replaced.
