Fan week on TSN...

First - make sure they are plugged in. The connectors get tired from the head and can become disconnected. Double check the fuses.

You didn't mention if they don't come on when the car gets hot or not. So this is assuming they don't come on when the car gets hot.

Jump the fan swtich that sits on the DS of the radiator up high. It should have a green and a yellow/white wire, when the fluid gets hot, the switch cloes and puts the fans on. Just short it w/ a screw driver. The fans should run. If they do - you probably need a switch, if they don't, check the wiring there.

Check the grounds to the fans. Just use a meter and go back to the - battery terminal. If you have some spare wire, you can wire them back to the battery to make sure they run. If you have an amp meter, you just jump the ground on the fan to the battery - terminal and put the amp meter between the + and the fan. It should be about 12amps then go down to 5-6 amps once running. One of mine needed a tap to get running.

Look at my update post a few lines down, Check the continunity from the relay socket.

If you get this far and they still don't work, you are in the same boat as I am but I haven't changed the relay yet.

Hope this helps...
