My cooling fan will not come on. I replaced it and still won't come on.
Last week after I changed my oil, the fan started working but the temperature gauge stayed at 0!
After a while the temp gauge worked again, but the fan would not come on again!!!!!
HELP!!!!!!

I'd look into the coolant temp sensor both the sensor and the wiring all along

Is it running hot? Is the outside temp above 70F with a/c running?
The fan will not be operated by the ECM until coolant temp reaches 225 or a little more and in cold weather it takes a long time sitting still running to reach that. If it isn't warm enough then the a/c high pressure will not be high enough for ECM to run fan for a/c needs.
