Default RE: Cooling fan stays on

it could be your temp sensor.... or radiator fan relay, here's the test procedures for both and component locations

continuity is a fancy way to say connection, get a voltmeter or a 9V battery and a small LED or bulb with two wires coming off it, with a voltmeter turn it to ohm's (that funky upside down horseshoe) and place one connnector on one side and one on the other, see if the needle jumps, if so then you have a connection, the cheap radioshack way (9v/bulb) take a piece of wire, connect one terminal of the battery to a post on the relay, connect the other terminal to one side of the bulb, then touch the other unconnected end of the bulb to the connector you want to test for a connection, the light comes on you've got continuity, light stays off, you don't....

Just spend $10.00 or so and buy a voltmeter, they're always good to have around... post a picture of the dial on it and I'll even show you exactly what settings to use

Your meter's continuity-test setting probably has a beeper. Touch the leads together & make it beep...

At room temperature the fan switch is supposed to be open. Like a switch that's turned 'OFF'. When it's hot (185 F?) it's supposed toswitch 'ON'. It sounds like yours is stuck ON all the time.

when testing those (temp sensors) they should read in the off position (no continuity) when at or below room temperature, if they don't they're bad

chances are that it's a temp sensor sending a bad signal then, either get a multi-meter or something to test continuity with and check them (the right way to do things) or start buying parts, buy a new temp sensor and replace it and see if that works (the expensive way)
