3.1L V6 cooling fan switch
Anyone know where to find a cooling fan switch for a 3.1L? Or does anyone know what I'd need to make my own?

If the A/C pressure switch was removed it will cause the fan to always run. If so, ground the pressure switch wire that goes to the ECM. Or wire it to a cabin switch to force the fan on when desired.
