Your fans should not come on when the car is cold. there are two temp sensors on the back of the water pump. One is for the guage and the other controls the fans if I'm not mistaken. You need to check the sensor that is closer to the ground. It may be disconnected. If this sensor is disconnected the fans will run. Also check the wires and all that. The actual sensor may be bad but check connections first.

Mine will run for a few minutes after the car is shut down, but that's it.

Something is not right; I'm surprised your battery isn't already shot.

this is a WAY better alternative than the opposite problem. If you don't have the money to fix it just disconnect your battery at night. LOL

no there all connected so go figure i guess. But yeah honestly id rather have it on all the time to. Just not when i want to start my car though. i think i might run them through a switch to remedy this.

Do you by chance leave your a/c on all the time because this would cause the fans to stay on. Try and fix the problem before you have to bypass it because then theres still a problem

A bad relay can do that. Get the service manual and a volt meter and start testing. There are 4 of them.
