1995 Nissan Sentra radiator fan

Check each of the three relays (identified on the cover) in the relay box in the engine compartment. Unplug each relay. The base should have plug-ins arranged something like this (ignore the periods; they're the only way I could add spacing):

. ---- (2)

---(3) . | (5)

. ---- (1)

While using jumper wires to connect fused battery voltage to terminal 2 and to ground terminal 1, you should have continuity between terminals 3 and 5. If the relays are OK, check the fan motor. Unplug it and connect jumper wires with fused battery voltage to terminal 2 and ground terminal 1. Looking at the oval shaped female plug, if the locking tab is at the top, terminal 1 is upper right, 2 is upper left.
