That's it. Remove the cover and that's the connector. Be careful removing the seperate white pigtail!!!
Ok finally found this old thread.. still working on this problem.
Finally got an obd reader of my own.
Took car into dealership, they replaced the IRCM/CCRM module, for another problem that occured.
I have replaced both sensors, one on the thermostat, the other on the engine block just below the thermostat housing body.
If I start the car with the Thermostat sensor plugged in, the car runs normaly. If I unplug the sensor first, the car races as if the engine is cold.
If I wait for the car to warm up before unplugging the sensor, the car runs normaly and the fan kicks on, with the open circut, which it should not.
The AC System has NOT ran in 5 years. I wonder if that has anything to do with it, or if there is an Engine control module somewhere that the fan is linked to some how?
I dunno.. Im ready to give up and just manually wire in a toggle switch under the dashboard for those really hot days when I need the fan to run..
