[Shotimes] cooling fan relay

[Zach Leahy]

Unfortunately the relay is part of the Integrated Relay Control Module
(IRCM).  There are other relays in that box for the fuel pump and other
parts.  It's a metal box attached to the radiator support under the plastic
"tool tray".  I would think you could find a known good one for cheap.

The temp sensor used is actually the same sensor that feeds the engine
temperature to the Powertrain Cotrol Module (PCM).  The PCM is what sends
the signal power to the relay to turn the fan on based on the engine
temperature.  The sensor is a 2 wire sensor in the housing near the
thermostat.  The one wire sensor is strictly used to control the temperature
gauge in the car.
