2005 Moon and Tune, Automatic, Two things (related or not?) 1 RAD fan isn't coming on with the defrost anymore. Relay? Where?
The other thing is that there is a sensor on top of the intake. It is clicking. I noticed it when I was poking around after I noticed the RAD fan issue. Could this be connected (AC system?) I haven't had a lick of trouble with this car but electrical issues bother me. Can anyone help me out on this one? Thanks in advance!!!

Did you try to run the Air condition as well? The fan should turn on when the AC compresser clutch engages on the belt. Then see if you can get the fan to run if you let the car sit idling for a long time.
Also, does the AC give you cold conditioned air? If not, maybe it will not run if low on freon.

The A/C compressor won't engage and the radiator fan won't run if the temperature is below freezing. If the temperature is above freezing it could be low refrigerant charge.
