===Cooling Fan Relays and Fuses===
The Low and High fan control circuits are separate from the ICE module all the way to the fan motor. The cooling fan Low (20-amp) and High (30-amp) relays are located in the engine compartment relay tray, and labeled on the lid of the box. The two fan fuses (30A and 40A) are in the same location.

===Testing===
The fan can be tested with the engine on or off (but preferrably off), by removing first the "Fan Low" relay, and putting a test lead, or a heavy wire jumper between relay socket contacts #30 and 87. A heavier than normal wire or test lead is required due to the large fan current. The fan should now run on low speed even with engine off. The same test can be repeated with the "Fan High" relay. Use Fuse Taps (from RadioShack etc.) or similar flat contacts in the relay socket to avoid damage to the socket.
