Very unusual problem with a 1998 gt . My car was runninig hot and i pulled over and sure enough my radiator fans were not coming on. I replaced the relay to fan # 1 and same problem still accured. Next I checked the engine coolant temperature sensor located on the lower portion of radiator and when the ignition is on and the sensor is unplugged the fans come on. I then replaced the coolant temperature sensor
and the same thing happened. If sensor is plugged in the fans will not come on but if it is left unplugged the fans run constantly as long as the ignition is on. Does anyone know where the problem might be. Also does anyone know if it is fan #1 fan #2 or fan #3 relay that controls the radiator fans. Tahnks for the time and help it is greatly appreciated |

QUOTE i was reading 14v going to the fan but ..it wasn't moving Was it the right (US drivers side) or left fan? The drivers side fan is the AC Condensor fan, which always has power and gets it ground from the relays. -------------------- Scott

The drivers side fan is the AC Condensor fan, which always has power and gets it ground from the relays. im not sure how he checked power but i was under the impression that he just backprobed the connector to the fan. in that case without a ground you wouldnt read anything since the voltage wasnt flowing to anywhere. think of the wires as a hose and the meter as a flow rate measuring device. put you finger over the end of the hose and theres no flow so theres nothing on the meter. -------------------- |
