WTF is with my crazy fan?!?!

Replace your coolant temperature sensor.... it should be the one in the thermostat housing...

It's old and not responding to the heat range it should anymore...

Get a new one and it will come on fine... the easiest way to be sure that's it is to unplug the plug from the sensor and jump the connection (if it's a 2 wire)... it should make the fan come on...

If not your problem is something else...

VW's and a lot of other cars do this as well... it's a good idea... Civic's only come on after the car is off if the power is still on... the fan won't come on w/o acc. power.

If the fan can come on with the power turned off.... there should be a warning lable under the hood somewhere... generally right up front on the radiator support.

Cool. Thanks Boo! I'll get the part on my way home tonight and try it out.
