Tripple pressure switch and E-fans! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey in a bit of a bundle here. I removed the A/C, bled teh coolant. However my E-fans wont come on, unless I manually trigger them/

Does the triple pressure switch need to be plugged in for the A/C harness to kick the fans on @ 203f?

thanks!

anyone? Iin the FSM manual it looks like the fans neg wires are connected to the triple pressure switch.

Yes. A dead switch or loose will cause that.

Update: The fans still kick in @ 203*f without the triple pressure switch. So it can be removed.

Strange. I'll have to double check that myself.

The FSM chart routed both Ground wires on the s14's A/C fan harness back to the triple pressure sensor.

My theory is the Triple pressure sensor is not a switch for the fan, but doubles as a relay and the ground wires still route back to the ECM.

I drove around for a while, unplugged the triple pressure switch from the harness, and sure enough the fans kicked in on low (203*f)

I just need to make sure its @ 203*F and not 212*f.

I can still press the A/C switch on the climate controls and the E-fans will kick in. The FSM states a few things control the Fans, triplepressure switch, ECT, VSS, and I forgot the other.
